Event ID 4108 — Terminal Services Per User Client Access License Tracking and Reporting

  • Article

Applies To: Windows Server 2008 R2

yellow

In Windows Server 2008, you can use the TS Licensing Manager tool to create (generate) reports to track the Terminal Services Per User client access licenses (TS Per User CALs) that have been issued by a Terminal Services license server. TS Per User CAL tracking and reporting is supported only in domain-joined scenarios because the information about the TS Per User CAL that has been issued to a user is stored as part of the user account in Active Directory Domain Services (AD DS).

For TS Per User CAL tracking and reporting to work, the computer account for the license server must be a member of the Terminal Server License Servers group in AD DS. If the license server is installed on a domain controller, the Network Service account must also be a member of the Terminal Server License Servers group.

Resolve

Identify and fix network connectivity issues

To resolve this issue, identify and fix any network connectivity problems between the Terminal Services license server and the Active Directory domain controller by doing the following:

  • Determine if there is a network connectivity problem by using the ping command.
  • Perform additional troubleshooting steps, if necessary, to help identify the cause of the problem.

To perform these tasks, refer to the following sections.

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.

Determine if there is a network connectivity problem

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

  1. On the license 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 domain controller (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 domain controller, and then press ENTER.

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

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

Perform additional troubleshooting steps

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 domain controller, try to ping the domain controller from another computer. If you cannot ping the domain controller from any computer, first ensure that the domain controller is running. If the domain controller is running, check the network settings on the domain controller.
  • 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 domain controller 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.

Verify

To verify that TS Per User CAL tracking and reporting is configured and working properly, do the following:

  • Use Review Configuration in TS Licensing Manager.
  • Create a report by using TS Licensing Manager.

To perform these tasks, refer to the following sections.

Use Review Configuration in TS Licensing Manager

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

To use Review Configuration:

  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.
  4. In the right pane, in the Configuration column, an entry of OK should appear in the row for the license server.
  5. To review the configuration details of the license server, right-click the license server that you want to review, and then click Review Configuration.
  6. There should not be any error or warning messages related to TS Per User CAL tracking and reporting in the Configuration dialog box.

Create a report by using TS Licensing Manager

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

To create a report:

  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, expand All Servers, and then select the license server.
  4. On the Action menu, point to Create Report, and then click Per User CAL Usage.
  5. In the Create Per User CAL Usage Report dialog box, select the scope for the report, and then click Create Report. The report will be created and a message will appear to confirm that the report was successfully created. Click OK to close the message.
  6. In the left pane, expand the node for license server, and then click Reports. The report will be listed in the right pane.
  7. Right-click the report, click Save As, and then specify the file name and location to save the report, and then click Save.
  8. Open the report and ensure that the report contains the appropriate information.
