A Windows Server 2008 R2 TS licensing server with the following roles installed & running:
TS Session Broker
Two Windows Server 2008 R2 terminal servers with the Terminal Server role installed & running.
The TS Licensing Manager indicates that there are a total of 50 TS CALs with 34 issued. The Discovery Scope is "Workgroup". However we are on a domain?!
On both terminal servers, under Terminal Services Configuration, the Licensing Diagnosis indicates: "License server <servername> is not available. This could be caused by network connectivity problems, the Terminal Services Licensing service is stopped on the license server, or TS Licensing is no longer installed on the computer."
Some thin clients experience the following error message when trying to connect: "The remote session was disconnected because there are no Remote Desktop License Servers available to provide a license. Please contact the server administrator."
