A domain administrator or local administrator incorrectly receives a warning message “Cannot find a valid Terminal Services Licensing Server” when this user account logs on to a Windows Server 2008 Terminal server

Symptoms

Consider the following scenario:

  • You enable the License server security Group Policy on a Terminal Services Licensing (TS Licensing) server that is running Windows Server 2008.

  • You add a terminal server to the "terminal server computers" group on the TS Licensing server.

  • You create a terminal server session to the terminal server by using a domain administrator account or a local administrator account.

In this scenario, you receive one of the following warning message balloons when you log on to the terminal server:

  • Cannot find a valid Terminal Services License Server

    Terminal Services will stop working because this computer is past its grace period and has not connected to a valid terminal services license server. Click this message to launch the Terminal Services Configuration tool to specify a valid license server.

  • Cannot find a valid Terminal Services License Server

    Terminal Services will stop working if this computer does not connect to a valid Terminal Services license server within 2 days. Click this message to launch the Terminal Services Configuration tool to specify a valid license server.


Note If you run the Licensing Diagnosis tool in the Terminal Services Configuration MMC snap-in (Tsconfig.msc), you notice that the terminal server is connected to the TS Licensing server successfully.

Cause

This issue occurs because the Tlsbln.exe (Windows Terminal Services Balloon Reminder) on the terminal server incorrectly performs a security check and reports a false warning message.

Workaround

To work around this issue when you log on to a terminal server as a domain administrator, use one of the following methods. To work around this issue when you log on to the terminal server as a local administrator, use only Method 1 or Method 2:

Method 1

Ignore the false warning message balloon. Then, use the Licensing Diagnosis tool to check whether the terminal server discovers the TS Licensing server.

Method 2

Use Task Scheduler to disable Tlsbln.exe. To do this, follow these steps:

  1. Click Start, type Task Scheduler in the Search box, and then click Task Scheduler.

  2. In Task Scheduler, expand Task Scheduler Library, expand Microsoft, expand Windows, expand termsrv, and then click licensing.

  3. Right-click TlsWarning that is displayed on the right side column of the Task Scheduler, and then click Disable.

Method 3


Add the domain administrators group to the "terminal server computers" group on the TS Licensing server.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More Information

This hotfix only corrects the warning balloon message if you log on to the terminal service session as a domain administrator. If you want to log on to the terminal service session as a local administrator, use the applicable workarounds that are described in the "Workaround" section.
