Troubleshooting Management Point Communication

Updated: September 1, 2010

Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2

The following are potential issues with Configuration Manager 2007 management point site systems that provide client computers with installation prerequisites, client installation source files, configuration details, advertisements, and software distribution package source file locations. Additionally, management points receive inventory data, software metering information, and status and state messages from clients. If clients cannot access or communicate correctly with a management point, they will be unmanaged.

Regardless of the number of management point site system roles installed on site systems in a site, clients only communicate with the default management point or proxy management point (intranet clients) or their assigned Internet management point (Internet-based clients).

ImportantImportant
You must download, install, and configure WebDAV manually on management points that are running Windows Server 2008. For more information, see How to Configure Windows Server 2008 for Site Systems.

For additional troubleshooting help, use the Management Point Troubleshooter from the System Center Configuration Manager 2007 Toolkit V2 (http://go.microsoft.com/fwlink/?LinkId=201513). Before you run the Management Point Troubleshooter for a site in native mode, export a certificate with client authentication capability to a file that can be accessed from the computer that runs the Management Point Troubleshooter.

For successful client computer installation and management, clients must be able to connect to the default or assigned management point computer.

Solution

To verify that a client can access the management point, use the Web browser installed on the client to connect to the management point list address and verify that the list of installed management points for the site is displayed.

WarningWarning
If the site is in native mode, you must install a certificate in the Web browser before you run these commands or the connection will fail as described in the Troubleshooting section An Internet Explorer Error Occurs When Troubleshooting Management Point Communication for Sites Configured to Operate in Native Mode.

  • For mixed mode clients, use the following: http://<ServerName>/sms_mp/.sms_aut?mplist, where <ServerName> is the NetBIOS name for the management point computer.

  • For intranet-based, native mode clients, use the following: https://<ServerName>/sms_mp/.sms_aut?mplist, where <ServerName> is the FQDN for the management point computer if an FQDN is specified in the site system properties or the short name if an FQDN has not been specified.

  • For Internet-based clients, use the following: https://<ServerName>/sms_mp/.sms_aut?mplist, where <ServerName> is the Internet FQDN for the Internet-based management point computer.

    ImportantImportant
    If a site is configured to use a custom Web site, the custom port must also be used, as in the following example: http://<ServerName>:<port>/sms_mp/.sms_aut?mplist.

For successful client computer installation and management, Configuration Manager 2007 clients must trust the management point computer. When clients communicate with a management point, the management point certificate is verified by clients to establish the trustworthiness of data sent by the site system to clients.

noteNote
In mixed mode sites, a management point certificate is created and signed by the site's trusted root key to enable clients to trust the management point site system. In native mode sites, the Web server certificate installed on the management point is signed by a certification authority that is trusted by the clients.

Solution

To verify that a client can view the management point certificate, use the Web browser on the client to verify that the management point certificate information (a long list of numbers and letters) is displayed.

WarningWarning
If the site is in native mode, you must install a certificate in the Web browser before you run these commands or the connection will fail as described in the Troubleshooting section An Internet Explorer Error Occurs When Troubleshooting Management Point Communication for Sites Configured to Operate in Native Mode.

  • For mixed mode clients, use the following: http://<ServerName>/sms_mp/.sms_aut?mpcert, where <ServerName> is the NetBIOS name for the management point computer.

  • For intranet-based, native mode clients, use the following: https://<ServerName>/sms_mp/.sms_aut?mpcert, where <ServerName> is the FQDN for the management point computer if an FQDN has been specified in the site system properties or the short name if an FQDN has not been specified.

  • For Internet-based clients, use the following: https://<ServerName>/sms_mp/.sms_aut?mpcert, where <ServerName> is the Internet FQDN for the Internet-based management point computer.

    ImportantImportant
    If a site is configured to use a custom Web site, the custom port must also be used, as in the following example: http://<ServerName>:<port>/sms_mp/.sms_aut?mpcert.

When troubleshooting native mode management points by using the MPLIST and MPCERT troubleshooting Web addresses, you receive a Microsoft Internet Explorer error similar to the following:

  • Internet Explorer cannot download .sms_aut?/mplist from <management point name>

  • Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later

Solution

Native mode client-to-server communication with a management point requires mutual authentication by using computer PKI certificates. Because Web browsers do not grant access to certificates in the computer store, you must export a computer certificate with the private key from the computer store and import it into the Web browser. This enables the management point to authenticate the Web browser that is using the MPLIST and MPCERT troubleshooting tests.

The following procedures can be used to import a computer certificate into the client computer Web browser if it is using Microsoft Internet Explorer:

  • Export the client certificate.

  • Import the client certificate into the client computer's Internet Explorer personal certificate store.

To export the native mode client certificate from computers running Windows 7 or Windows Vista

  1. On the native mode client that is running Windows Vista and will be used to test management point communication, log on as a local administrator, click Start, type MMC into the Search box, and then press ENTER.

  2. In the empty console, click File, and then click Add/Remove Snap-in.

  3. In the Add orRemove Snap-ins dialog box, select Certificates, and then click Add.

  4. On the Certificates snap-in page, select Computer account, and then click Next.

  5. On the Select Computer dialog box, ensure that the option Local computer: (the computer this console is running on) is selected, and then click Finish.
