Interpreting Userenv log files

Updated: March 2, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

This topic explains how to interpret userenv log files.

Userenv Logging

When you enable userenv logging, you can perform debug logging of the user profile and the system policy processes. Userenv log files also contain information about the status of each Group Policy extension, such as Application Deployment, Security, and Folder Redirection. Userenv log files reveal what is occurring in the background as a user logs on. Userenv log files are especially useful because they be can be used to troubleshoot Windows 2000 operating systems, in which you cannot use Resultant Set of Policy (RSoP). In addition, if Active Directory replication is not working, RSoP will not work, leaving userenv log files as the only troubleshooting option. RSoP also depends on Windows Management Instrumentation (WMI), which might also fail and leave you with no option but to analyze the userenv log files. With verbose logging, information is logged every second; if something fails you can review the userenv logs and pinpoint the likely source of failure.

Userenv log files contains information about the following:

  • Group Policy settings that are not processed or not applied as expected

  • Folder redirection that does not occur

  • Profile or registry hive load, unload, or deletion failures

  • Logon script, or script not applied as expected

  • Default behaviors occurring because a slow link was detected

  • Roaming profile issues

  • Slow logon issues

  • Whether a given GPO is accessible, and if not, why access was denied.

  • The name of the domain controller that is accessing SYSVOL.

What is in the Userenv log?

The example of the Userenv log in this section shows the type of details of errors in core Group Policy processing that the Userenv log provides. Reading from left to right, this log shows a process code (for example, cc.500), the time it was processed (note the date is not displayed), the process name, and a short statement of the error. The Userenv log displays Group Policy process failures and warnings.

Sample Userenv log
USERENV(178.17c) 13:48:51:089 MyRegUnLoadKey:  Failed to unmount hive 00000005
USERENV(178.17c) 13:48:51:089 DumpOpenRegistryHandle: 3 user registry Handles leaked from \Registry\User\S-1-5-21-2127521184-1604012920-1887927527-2193396
USERENV(178.17c) 13:48:51:089 UnloadUserProfileP: Didn't unload user profile <err = 5>
USERENV(178.2e8) 13:52:00:708 GetGPOInfo:  Local GPO's gpt.ini is not accessible, assuming default state.
USERENV(178.600) 13:52:09:452 GetGPOInfo:  Local GPO's gpt.ini is not accessible, assuming default state.
USERENV(178.4d4) 13:52:15:020 PolicyChangedThread: UpdateUser failed with 6.
noteNote
The Userenv log has a maximum size of 1 megabyte (MB). At system startup, if the log file exceeds 1 MB, the contents is copied into a Userenv.bak file and a new Userenv log is created. If the system remains running and is not restarted, the log file exceeds 1 MB.

General Userenv.log Messages

The following messages have the same meaning no matter where they appear in the log:

  • Failed to Allocate…

  • Failed to Create…

  • Failed to Set…

  • Failed to Get…

  • These errors normally indicate a problem with system resources at the time when they were called. If you receive multiple errors at the same time, your computer could be having integrity problems. To avoid these problems, try to ensure that the computer is as close to a base install of Windows as possible by removing all third party software programs. If this option is not possible for you, install a new version of Windows and all available service packs on a test machine. If the error is no longer appearing in the log file, slowly install third party software, one program at a time. Monitor the Userenv log after each program is installed to determine which program is causing the error.

The following messages also have the same meaning no matter where they appear in the log:

  • Calling function <function failed>

  • Calling function <function returned>

  • These entries indicate that an underlying function was called and that there was an error in the transaction. Determine which function the entry is causing the error by viewing the error text, and then locate the function that failed in the log. After you have identified the failed function entry in the log, get the return code and start troubleshooting the failed function from there.

ApplyGroupPolicy Messages

ApplyGroupPolicy: Entering. Flags = %x

You use flags to determine what processing Group Policies need to do and what some of the Client Side Extensions (CSEs) are doing. Flags are hexadecimal bits that might need to be converted if the number is above nine.

 

Hexadecimal Description

0x00000001

Machine Policy (The absence of a 1 = User Policy)

0x00000002

Background Refresh

0x00000004

Apply Directory Services Policy

0x00000008

Do not Wait on Network Services

The values listed in the following table are added to the flags after processing.

 

Hexadecimal Description

0x00010000

Background Thread Processing

0x00020000

Change in Control Panel Settings

0x00040000

Slow Network Connection

0x00080000

Verbose output to the event Log

0x00100000

Forced Refresh

0x00800000

Planning Mode

CheckGPOs Messages

Most of the log messages from this function are self-explanatory. The following is the most common error that users ask about in relation to CheckGPOs log messages.

CheckGPOs: No GPO changes but couldn't read extension %s's status or policy time.

Group Policy stores the status and the time of each extension as needed for the machine and every user that logs onto the machine. They are stored in the following registry locations:

MACHINE

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine\Extension-List

USER

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\<SID>\Extension-List

If you receive this error, check your registry permissions for any explicit denials on the registry settings. Also, check for any third-party software that might manipulate this key. Some third parties change the Group Policy cache in both the file system and registry to have their product mimic Group Policy.

EnterCriticalPolicySection Messages

This is a potentially serious log message. It could indicate that certain portions of the operating system have become corrupt due to improper shut-down or system crashes. It could also indicate a system resource problem, similar to the "Failed to…" errors mentioned earlier in this section. To troubleshoot this issue, remove all third-party software to determine if a non-Microsoft program is causing this error. If that does not fix the problem, start with a clean installation of Windows, install all necessary service packs, and then introduce the clean computer into your environment. Monitor the Userenv log while installing any additional programs to determine what could be causing this error.

GPOThread

GPOThread: Next refresh will happen in %d minutes

This is an informational message. It is the only place within the operating system that indicates when the next time Group Policy will refresh.

LeaveCriticalPolicySection

See the "EnterCriticalPolicySection" section earlier in this document.

LibMain

LibMain: Process Name: %s"

This is an informational message. This message appears in the userenv.log when an application loads Userenv.dll within its space. Userenv has many exported functions that deal with loading and unloading the user’s profile. Therefore, many application need to go through Userenv to get the profile of the currently logged on user for application specific settings. This message indicates which application is loading an instance of Userenv.dll.

ProcessGPO

ProcessGPO: Found flags of: %d"

This is an informational message. To determine what the flag in the message means, see the following list:

  • 0 = Both user and Computer Configuration are Enabled

  • 1 = User Configuration is Disabled

  • 2 = Computer Configuration is Disabled

ProcessGPO: Found machine version of: GPC is %d, GPT is %d"
ProcessGPO: Found user version of: GPC is %d, GPT is %d"

These two messages are misrepresented in the Userenv log. It states GPC and GPT but it does not actually read from the GPT. It reads both settings from the GroupPolicyContainer Object (GPC) and not SYSVOL. The Attribute it reads is the Version number, which is stored as an integer value. If you believe you have a SYSVOL problem, run GPOTOOL to determine where errors might exist.

ProcessGPORegistryPolicy

ProcessGPORegistryPolicy: Failed to create archive file with %d"

The archive file in question is named ntuser.pol and is located in the user's profile. If you receive this error in the Userenv log, determine whether you are having problems with profile loading or unloading. Also, make sure that the user has write permissions to the profile folder because ntuser.pol is created in the root of the user profile.

ProcessGPOs: Machine role is %d."

This entry includes a decimal number at the end (%d). To determine what processing is going on within Userenv, see the following list:

  • 0 = Standalone machine that is not a member of a Directory Services Domain

  • 1 = The machine is a member of a NT4 domain

  • 2 = The machine is a member of a domain which supports Directory Services.

  • 3 = The machine is a domain controller

This information helps you determine what kind of machine you are troubleshooting, which could indicate why a policy is or is not applying.

ProcessGPOs: The DC for domain %s is not available. aborting"
ProcessGPOs: The DC for domain %s is not available."

These messages can be caused by network problems or the Windows XP Fast-User logon Optimization option. Try turning off the Fast-User Optimization option. If that does not cause the errors to stop, you might have a network problem. Troubleshoot this as you would any network problem.

ProcessGPOs: DSGetDCName failed with %d."

DsGetDCName is a public API that performs Domain Controller discovery. Troubleshooting this most of the time will involve name resolution. You can simulate this call by using the utility nltest.exe. Use the command ipconfig /flushdns before using nltest when you are taking a network monitor trace. Windows has a client-side cache, and you want to capture the DNS data in the trace. The syntax for nltest is:

nltest /DSGETDC:  DomainName

ProcessGPOs: GetNetworkName failed with %d."

This function writes the FQDN of the domain into the Group Policy Cache. Many of the CSEs and Components that are policy implemented look for this name in the cache. This return code should be used wit the net command to determine the error message. Some of the lower-level functions in this name are Winsock library calls. If this is appearing and you are seeing some policies fail, make sure the machine is free from any viruses, worms, or other forms of malicious software.

ProcessGPOs: Calling GetGPOInfo for normal policy mode"

This is an informational message. This lets you know that you are processing policy in normal mode.

ProcessGPOs: Calling GetGPOInfo for replacement user policy mode"

This is an informational message. This message appears if the computer is in Group Policy loopback mode. Group Policy uses the user policy settings from the location of the computer object, and Group Policy does not honor any of the user policy settings based on the user’s object in Active Directory.

ProcessGPOs: Calling GetGPOInfo for merging user policy mode"

This is an informational message. This message appears when the computer is in Group Policy loopback mode. Group Policy merges the user specific policy settings based on where the user’s object is located in Active Directory along with the location of the computer object settings in Active Directory.

ProcessGPOs: Extension %s skipped with flags 0x%x."

This message indicates that a client-side extension was skipped. Use the flag values to determine why the extension was skipped. Typically, it is background processing, but make sure it was not caused by an error.

ProcessGPOs: Extension %s ProcessGroupPolicy failed, status 0x%x."

This message appears if the extension has actually failed. Use the net command with the return status to determine what the possible causes are. Enable additional logging for the extension specified to determine a more accurate error. Remember the status returned to ProcessGPOs is mapped to a more standard Windows Error. More specific errors might be revealed in the extension's debug log.

ProcessGPOs: Couldn't read status data for %s. Error %d. ignoring..

This is an informational message. This message appears to be an error, however the Group Policy engine automatically processes the extension because it cannot read the status data, hence the "ignoring" notation at the end of the message.

ProcessGPOs: Computer Group Policy has been applied.
ProcessGPOs: User Group Policy has been applied.

These are informational messages. These messages indicate that the Group policy has applied policy to the best of its ability. It does not mean that there were not any errors.

ProcessGPOs: Leaving with %d."

This is an informational message. If this value is not 0, the policy encountered a problem when it was applied. The fact that it appears in the log as well as the two messages above means the Group Policy was able to handle the error gracefully and move on.

SearchDSObject

SearchDSObject: Searching <%s>"

This function is used to determine which policy objects are within scope for the logging on user or computer. It should have a Distinguished Name (DN) of the object in Active Directory. The DN should either be a Site object, Domain object, or an Organizational Unit object. This is the location in Active Directory in which the Group Policy engine is searching for linked policy objects.

SearchDSObject: Too many linked GPOs in search.

This error message is not actually a Group Policy error but rather an LDAP Error, LDAP_SIZELIMIT_EXCEEDED. The value is determined by the Search Request.

SearchDSObject: Found GPO(s): <%s>

Here is an example from a Userenv.log file.

SearchDSObject:  Found GPO(s):  <[LDAP://CN={31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=corp,DC=mstep,DC=com;0]>

Notice there is a ;0] at the end of the message. This value has meaning and it will appear on every policy that is linked. To determine the value, see the following table :

  • 0 = This is the default setting. The policy is enabled

  • 1 = This policy is disabled

  • 2 = This policy will be forced or cannot be overridden and will win all ties against block policy inheritance

  • 3 = Settings 1 and 2 are both enabled hence the policy will be disabled.

SearchDSObject: <%s> has the Block From Above attribute set"

The Block From Above attribute prevents a linked policy from being inherited by a Site, Domain, or OU beneath it. Generally, this is only set at an OU level, however the option is available anywhere a policy can be linked. This setting is stored on the actual container object, just as the policies that are linked to the container. This specific value can be found in on the attribute Gpoption. This attribute is an integer value and only has two settings: zero (0) (default) indicates normal propagation of the policy to the container, and one (1) turns on Block Policy Inheritance, which prevents polices higher in the tree from applying to the container or objects in the container. A policy that has No Override or Force, ignores the Block Policy Inheritance flag and still applies.

RETURN CODES

This section contains the return codes listed throughout a Userenv.log. You can use this section to determine what the codes mean and how to apply them to the specific function that is returning them.

General Rules

Most functions return true, false, or a status code. For this documentation true or successful is represented by a 0. False or unsuccessful is represented by a 1. Status codes have different meanings. This section documents most of the well known status messages.

Most return codes, after they are converted from hexadecimal to decimal, can be described by using the net command. The command-line syntax is:

NET HELPMSG Number

Messages that begin with 0xC or anything similar will probably not work with the net command and are listed in the "Return Codes that cannot be converted with the net command " table later in this document.

Return Codes

 

Return Code Description

1332

None Mapped. This usually means you have a SID designated in either Group Policy or Security Policy that is no longer valid on the domain. Typically, this happens when a user or group is created in the domain, assigned to a specific setting, and then later is deleted from the domain without updating the policy to remove the user. This is typically associated with a user or group instead of a computer account. Usually you can look through the event logs and find an event that has a return ID of 1332. This message is also represented as 0x534. To solve the problem, find the entry that has the user or group name or a SID that does not resolve to a user name and remove it.

1355

No such Domain. Typically, this is a name resolution problem, and most of the time it will be with DNS. There are some functions that return as 1355. If you are using a legacy operating system such as Windows NT, these messages are not as serious as if you are using Windows 2000, Windows XP, or Windows Server 2003. Another possible cause is NetBois. Some environments have DNS lookups look to a WINS server for name resolution. If you are certain you have ruled out Name resolution then start with a network trace to determine where the computer is trying to contact and troubleshoot from there. This error is also seen as 0x54b

1722

RPC Server is unavailable. This error can mean several different things. Check for name resolution problems first. This is a common cause of this error. The next thing is to use a utility, like Port Query or RPC Ping, to make sure that client and the target server are communicating. Due to Windows dependency on RPC, any failures in RPC can have a repercussions. Make sure the critical services like the RPC Endpoint Mapper and RPCSS are turned on. Also make sure port 135 is not blocked so clients can bind and connect to the endpoint mapper. Finally, you can take a network trace to make sure RPC connectively is valid. Because RPC traffic is usually encrypted, you need someone that knows how to look for RPC in a network trace.

14

Not enough storage is available to complete this operation. This is usually a resource problem, specifically memory allocation. Verify that the computer has enough resources to complete its tasks. If a process started exceeding its virtual memory limit, you can get this message. Restarting usually clears the problem, however this might be temporary and the problem might continue to occur. Start monitoring the computer's performance after the restart to see if you can determine what is causing the heavy resource usage. Use Performance Monitor to base line and spot memory usage trends.

1908

Domain Controller could not be found for this domain. Use the same troubleshooting as you would for a 1355 error message

5

Access Denied. There is a security descriptor that is preventing the current credentials from accessing the resource. This could also be a privilege access that is being denied. For example, the SeNetworkLogonRight allows security principals to connect to the machine and access resources. If a user was not given this privilege they would get the Access Denied error. Check the Permission on the resource. If the function is accessing the registry, find out which key it is attempting to use. If it is attempting to access a file, check the permissions on the file. After you have exhausted the possibility of checking permissions, check the security policy for the proper privileges.

1115

Shutdown in Progress. The system is shutting down. This event overrides most events that occur in the operating system. If the shutdown is unexpected, check the event logs to determine why the system shut down.

1326

Unknown user name or bad password. Check the user name and password you are logged on with. If you had a password change log off and log on again with the new password and see if that resolves the problem.

1753

There are no more endpoints available from the endpoint mapper. Start off by stopping third-party services because this error usually occurs when a RPC application consumes all of the available endpoints or the server is very busy. Follow up with troubleshooting steps provided by the 1722 error.

1317

The specified user does not exist. This is usually the case where you have a SID that no longer resolves to a user name, either because it has been deleted or because it is a SID from a trusted domain where the trust is not working. It could also be that you have a user name that cannot be converted to a SID. You can use either the name2sid.exe or lua.exe utility to see if the name is valid in the current domain as well as trusted domains.

1398

There is a time or date difference between the client and server. Verify that your client, server and the KDC are within five minutes of each other. Make sure time zones and date are correct as well. Check the event log to see if you are having any W32time errors. Kerberos defaults to five minutes of allowable time skew. Any time past five minutes causes errors.

2

The system cannot find the file specified. This message is very similar to the error 3 message and you troubleshoot them the same way. This message indicates that the computer cannot locate either the file or the path that you have told it to look for. This occurs if you try to connect to a UNC path that is not valid (for example, reading policy from SYSVOL). Find the path or file in question and attempt to navigate to that path under the proper credentials. If you want to navigate to the path under the computer context. use /interactive at a command line. If you perform a network trace during the event, you can get some good information about the problem.

3

The system cannot find the path specified. For more information, see Error 2.

53

The network path was not found. This usually is the sign of a name resolution problem and most of the time it is referencing a NetBIOS name resolution problem. Verify that the NetBIOS cache using the tool nbtstat is not causing this error. Also, make sure there is not a LMHOSTS file on the computer, and, if there is, make sure it is correct. Finally, verify that WINS is configured correctly. When you have exhausted NetBIOS resolution do not forget to look at DNS resolution because DNS can effect lookup names in WINS and vice versa. You can also identify the path and attempt to connect to it via IP address. Also, IPSec can generate this error message too. When a computer has IPSec turned off and it is attempting to communicate with a machine that has IPSec turned on, this error can occur.

32

The process cannot access the file because it is being used by another process. Another process has a lock on the file and is preventing access to the file. Restarting usually fixes this issue. If you discover that you need to restart often, you need to identify the process that is not releasing the file. You can use a tool like OH.exe to locate the offending process. After you identify the process, you will need assistance from the vendor to determine why the process is not releasing the file. Verify that you do not have any user mode applications that are holding the process open. To fix this problem, try stopping services, such as Realtime virus scanners, Open File Agents.

Return Codes that cannot be converted with the net command

 

Return Code Description

0xc000015b

Requested Logon type was not granted. Windows provides for multiple Logon types. Interactive Logon is logging on at the console of the machine. Network Logon is connecting to a resource on a remote machine. The function has requested to log on with certain credentials that do not permit the requested log on type.

0xc000023c

The network is unreachable. There is an underlying networking problem. Start by troubleshooting basic connectivity. When using TCP/IP, check to make sure that the address, subnet mask and gateway are correct. To determine the location of the problem, use the ping utility to ping the loop back adapter first, then the IP address of the current machine that is having a problem, then the default gateway and then an address that is past the gateway.

0xc000026d

DFS is unavailable. Troubleshoot basic connective to DFS shares. If possible, use a network sniffer, such as Network Monitor, to assess whether the problem is on the server or the client.

0xc00000be

Bad Network Path. The path that was used to connect to another machine was invalid or there could be name resolution issues. Verify the path does not have invalid characters. Look for additional errors in the log that could support a name resolution problem. These errors can include 53 and 1355. Trying doing a directory of the path from a command prompt using the fully qualified name, the NetBIOS name and lastly the IP address itself. Also rule out the possibility of IPSec.

0xc0000064

No such user. A request specified a user account that is not on the system the function targeted. Verify that the user does exist. If the user requested resides in Active Directory make sure Active Directory replication is working, and that the user is present on the authenticating domain controller.

0xc000006a

Wrong Password. The function attempted to use an invalid password for the credentials it was impersonating or in the context of. Check and make sure Active Directory replication is working. A large number of these events could be a service account that has had a password change but the entry in the machine has not been updated with the new password. Additionally, multiple versions of these events can trigger account lockouts.

0x80090303

Target Unknown. Typically, this error occurs when a security function fails. Start your troubleshooting by looking at the calling function to try to determine what Group Policy was attempting to do when it called the security related function. Look at the event logs to see if the computer is having other security related problems such as policy not applying, logon problems, or prompting for credentials when the credentials are good. Another area where you can see this is with Kerberos when the Service Principal Name that is being requested is not listed in the database. Use a network trace to determine if this is the cause. Also, turn on Kerberos logging at the targeted computer.

0x8009030c

Logon Denied. Group Policy impersonates both the computer and the user when it determines the scope of policy, meaning it acts on behalf the user. This could be a machine account needing its password reset or a user account that has some problem. Check Active Directory to make sure the user account is set up correctly. Use a utility, like netdom or nltest, to test the computer account's password.

0x80090324

Time Skew. The majority of the time this is a Kerberos issue. Make sure your client, server and the KDC are within five minutes of each other. Verify that time zones and date are correct too. Check the event log to see if you are having any W32time errors. Kerberos defaults to five minutes of allowable time skew. Any time past that causes errors.

0x80090311

No authenticating authority. Normally, this implies that the machine cannot contact a Domain Controller or from a Kerberos perspective (that is, a KDC). Troubleshoot this by turning on Kerberos Logging and getting a network monitor trace to determine where the computer is trying to contact for authentication. If you are traversing a trust then Netlogon log on Domain Controllers in both domains and if possible run a simultaneous trace to help pinpoint the failure.

LDAP ERROR CODES

Some of the messages return LDAP Error codes. You can recognize these error codes because the function usually starts with ldap_.

 

Error Code Description

85

Timeout. Verify network connectivity. Ping the target computer and check the response time. Verify that the targeted server is responding on port 389 and port 3268 if it is a Global Catalog server.

82

Local Error. Check the Directory Services event log and make sure Active Directory is healthy on this machine. Check for memory consumption as well as CPU time for LSASS. If these checks do not turn up any other errors, turn on Directory Services logging.

53

Unwilling to Perform. The specific command was refused by the LDAP Server. The most direct way to find the problem is to turn on Directory Service Logging on the targeted server that returned the error message. By getting a network monitor trace while this happening, you can identify the request that the client is sending to the server. The additional logging helps you determine why the server is returning the message. This is not always an error message. It is uncommon, but occasionally Group Policy requests that the computer do something that it cannot, which causes this error.

7

Authentication Method not supported. Look at the type of Authentication you are using to connect to the targeted LDAP server. In most cases, you should begin Kerberos Troubleshooting. Turn on Kerberos Logging on the client and the KDC. Also, a network trace might help you locate the problem.

81

Server Down. The targeted LDAP Server is not responding. Check the network, the proper LDAP ports for the given server, and any router connections. Start investigating the health of the targeted server.
