yellow

A terminal server must be able to contact (discover) a Terminal Services license server in order to request Terminal Services client access licenses (TS CALs) for users or computing devices that are connecting to the terminal server.

Note:  A terminal server running Windows Server 2008 can only communicate with a license server running Windows Server 2008.

Event Details

Product: Windows Operating System
ID: 1129
Source: Microsoft-Windows-TerminalServices-RemoteConnectionManager
Version: 6.0
Symbolic Name: EVENT_LICENSING_GRACE_PERIOD_ABOUT_TO_EXPIRE
Message: The TS Licensing grace period is about to expire on %1 and the service has not registered with a license server with installed licenses. A TS Licensing server is required for continuous operation. A terminal server can operate without a license server for 120 days after initial start up.

Diagnose

This error might be caused by one of the following conditions:

  • There is a network connectivity problem between the terminal server and the license server.
  • The license server is not correctly configured to be automatically discovered.
  • The terminal server cannot automatically discover (contact) a Terminal Services license server.
  • The Terminal Services Licensing service is not running on the license server.

There is a network connectivity problem between the terminal server and the license server

To determine if there is a network connectivity problem between the terminal server and the license server, use the ping command.

Note:  The following procedures include steps for using the ping command to perform troubleshooting. Therefore, before performing these steps, check whether the firewall or Internet Protocol security (IPsec) settings on your network allow Internet Control Message Protocol (ICMP) traffic. ICMP is the TCP/IP protocol that is used by the ping command.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To determine if there is a network connectivity problem between the terminal server and the license server:

  1. On the terminal server, click Start, click Run, type cmd, and then click OK.
  2. At the command prompt, type ping server_FQDN, where server_FQDN is the fully qualified domain name (FQDN) of the license server (for example, server1.contoso.com), and then press ENTER.

    If the ping was successful, you will receive a reply similar to the following:

    Reply from IP_address: bytes=32 time=3ms TTL=59

    Reply from IP_address: bytes=32 time=20ms TTL=59

    Reply from IP_address: bytes=32 time=3ms TTL=59

    Reply from IP_address: bytes=32 time=6ms TTL=59

  3. At the command prompt, type ping IP_address, where IP_address is the IP address of the license server, and then press ENTER.

If you cannot successfully ping the license server by IP address or by FQDN, see the section titled "Identify and fix network connectivity issues."

The license server is not correctly configured to be automatically discovered

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To determine if the license server is correctly configured:

  1. Open TS Licensing Manager on the license server. To open TS Licensing Manager, click Start, point to Administrative Tools, point to Terminal Services, and then click TS Licensing Manager.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. In the left pane, click All Servers, click the name of the license server, and then on the Action menu, click Review Configuration.
  4. In the Configuration dialog box, if there is a message indicating that terminal servers will not be able to automatically discover this license server, see the section titled "Configure the discovery scope for the Terminal Services license server."

The terminal server cannot automatically discover (contact) a Terminal Services license server

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To determine if the terminal server can discover a license server:

  1. Open Terminal Services Configuration on the terminal server. To open Terminal Services Configuration, click Start, point to Administrative Tools, point to Terminal Services, and then click Terminal Services Configuration.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. In the left pane, click Licensing Diagnosis. Under Terminal Services License Server Information, if at least one license server is not listed as discovered, see the section titled "Specify a Terminal Services license server for the terminal server to use."

The Terminal Services Licensing service is not running on the license server

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To determine if the Terminal Services Licensing service is started:

  1. Open the Services snap-in on the license server. To open the Services snap-in, click Start, point to Administrative Tools, and then click Services.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. In the Services pane, if the Status column for the Terminal Services Licensing service does not display Started, see the section titled "Start the Terminal Services Licensing service on the license server."

Identify and fix network connectivity issues

To resolve this issue, identify and fix any network connectivity problems between the terminal server and the Terminal Services license server.

Note:  The following procedures include steps for using the ping command to perform troubleshooting. Therefore, before performing these steps, check whether the firewall or Internet Protocol security (IPsec) settings on your network allow Internet Control Message Protocol (ICMP) traffic. ICMP is the TCP/IP protocol that is used by the ping command.

To perform these procedures, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

If you can successfully ping the license server by IP address, but not by FQDN, this indicates a possible issue with DNS host name resolution.

If you cannot successfully ping the license server by IP address, this indicates a possible issue with network connectivity, firewall configuration, or IPsec configuration.

The following are some additional troubleshooting steps that you can perform to help identify the root cause of the problem:

  • Ping other computers on the network to help determine the extent of the network connectivity issue.
  • If you can ping other servers but not the license server, try to ping the license server from another computer. If you cannot ping the license server from any computer, first ensure that the license server is running. If the license server is running, check the network settings on the license server.
  • Check the TCP/IP settings on the local computer by doing the following:
    1. Click Start, click Run, type cmd, and then click OK.
    2. At the command prompt, type ipconfig /all, and then press ENTER. Make sure that the information listed is correct.
    3. Type ping localhost to verify that TCP/IP is installed and correctly configured on the local computer. If the ping is unsuccessful, this may indicate a corrupt TCP/IP stack or a problem with your network adapter.
    4. Type ping IP_address, where IP_address is the IP address assigned to the computer. If you can ping the localhost address but not the local address, there may be an issue with the routing table or with the network adapter driver.
    5. Type ping DNS_server, where DNS_server is the IP address assigned to the DNS server. If there is more than one DNS server on your network, you should ping each one. If you cannot ping the DNS servers, this indicates a potential problem with the DNS servers, or with the network between the computer and the DNS servers.
    6. If the license server is on a different subnet, try to ping the default gateway. If you cannot ping the default gateway, this might indicate a problem with the network adapter, the router or gateway device, cabling, or other connectivity hardware.
  • In Device Manager, check the status of the network adapter. To open Device Manager, click Start, click Run, type devmgmt.msc, and then click OK.
  • Check network connectivity indicator lights on the computer and at the hub or router. Check network cabling.
  • Check firewall settings by using the Windows Firewall with Advanced Security snap-in.
  • Check IPsec settings by using the IP Security Policy Management snap-in.

Configure the discovery scope for the Terminal Services license server

To resolve this issue, use Review Configuration in TS Licensing Manager to identify and, if possible, correct any issues that prevent the Terminal Services license server from being automatically discovered by terminal servers.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To review the configuration of the license server:

  1. On the license server, open TS Licensing Manager. To open TS Licensing Manager, click Start, point to Administrative Tools, point to Terminal Services, and then click TS Licensing Manager.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. In the left pane, click All Servers, click the name of the license server, and then on the Action menu, click Review Configuration.
  4. In the Configuration dialog box, review any messages that indicate that terminal servers will not be able to automatically discover this license server. For example, you might see either of the following messages:
    • This license server is not published in Active Directory Domain Services (AD DS). Terminal servers in the forest will not be able to automatically discover this license server.
    • This license server is not installed on a domain controller. Terminal servers in the domain will not be able to automatically discover this license server.

      Note:  The message in the Configuration dialog box that appears will depend on the discovery scope that has been configured for the license server. The current discovery scope for the license server is listed in the Configuration dialog box. The recommended discovery scope for a Windows Server 2008 license server is Forest. For more information about discovery scopes, see "Terminal Services License Server Discovery" in the TS Licensing Manager Help in the Windows Server 2008 Technical Library (http://go.microsoft.com/fwlink/?LinkId=101648).

  5. If the discovery scope for the license server is set to Forest, but the license server is not published in AD DS, you can click Publish in AD DS in the Configuration dialog box to publish the license server to AD DS. To publish the license server in AD DS, you must be logged on as an enterprise administrator to the forest in which the license server is a member.
  6. If the discovery scope for the license server is set to Domain, but the license server is not a domain controller, you should consider changing the discovery scope of the license server to Forest. To change the discovery scope of the license server, click Change Scope in the Configuration dialog box.

Specify a Terminal Services license server for the terminal server to use

To resolve this issue, specify a Terminal Services license server for the terminal server to use.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To specify a license server to use:

  1. On the terminal server, open Terminal Services Configuration. To open Terminal Services Confiiguration, click Start, point to Administrative Tools, point to Terminal Services, and then click Terminal Services Configuration.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. Under Licensing, double-click License server discovery mode.
  4. Select Use the specified license servers, and then enter the name or IP address of the license server for the terminal server to use.
  5. Click OK, and then click OK.

Note:  You can also specify a Terminal Services license server for the terminal server to use by using Group Policy.

  • To specify a Terminal Services license server for the terminal server to use, enable the Use the specified Terminal Services license servers Group Policy setting. This Group Policy setting is located in Computer Configuration\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Licensing. Note that the Group Policy setting will take precedence over the setting configured in Terminal Services Configuration.
  • To configure the Group Policy setting in Active Directory Domain Services (AD DS), use the Group Policy Management Console (GPMC). To configure the Group Policy setting locally on a terminal server, use the Local Group Policy Editor. For more information about configuring Group Policy settings, see either the Local Group Policy Editor Help (http://go.microsoft.com/fwlink/?LinkId=101633) or the GPMC Help (http://go.microsoft.com/fwlink/?LinkId=101634) in the Windows Server 2008 Technical Library.
