Terminal Services Licensing service

Hi,

My windows 2000 DC runs my domains Licensing server.  Yesterday my windows 2003 server (which we use for terminal services) has started to state that it cant allocate licenses to the clients.  The error message on client end is "the remote session wsa disconnected as there are no Terminal Server License Servers available to provide a license."

According to the licensing server there are still unallocated licenses to be allocated and none of the ones in use are near expiry date.  It is also activated.

Ive have used the LSview.exe tool that comes in the windows 2003 resource kit, and its says that the licensing server is running on my domain controller.

I have also attempted to use QA279561 to point the terminal server directly at the license server, but this also has not worked.

Any help would be most appreciated.
cheers

You'll need to setup the Terminal Services License Server on a Server 2003 machine; a W2k3 Terminal Server will not communicate with a TS license server on a W2k machine. In addition, you might need to configure a preferred license server (as described in the link you've found already).

Here's the TS Licensing white paper:
Windows Server 2003 Terminal Server Licensing
http://www.microsoft.com/windowsserver2003/techinfo/overview/termservlic.mspx

A few quotes from the White Paper:    
"A terminal server running Windows Server 2003 does not communicate with a terminal server licensing server running Windows 2000."
"Therefore, when upgrading terminal servers running Windows 2000, you need to install and activate a licensing server that runs Windows Server 2003, which communicates with terminal servers that run both Windows 2000 and Windows Server 2003."
"In most large deployments, the license server is deployed on a separate server, even though it can be co-resident on the terminal server in some smaller deployments."
"In Windows Server 2003, the licensing service can be installed on a workgroup-based server, a member server, or a domain controller. "
"It is also possible to override this discovery process by specifying a preferred license server (or multiple license servers) on a terminal server by using a WMI script. For three scripts that you can use to set preferred license servers, delete preferred license servers, or query preferred license servers, see 'Administration' later in this document."
"Although it is possible for non-domain controllers to be license servers in Windows Server 2003, it is important to note that domain license servers are not automatically discovered. You must configure a preferred license server on all terminal servers that need to communicate with non-Domain controller license servers configured as domain license servers. Enterprise domain license servers deployed on non-domain controllers are automatically discovered."

For the sake of completeness: You are aware that MS changed the licensing in W2k3 Terminal Services? In W2k Terminal Services, W2k and XP clients didn't need additional TS CALs; W2k3 Terminal Services now require TS CALs for every client, including XP.
