Consider the following scenario. A client computer connects to a Microsoft Windows 2000-based computer that has Terminal Services enabled. Additionally, the following conditions are true:
The client computer is running an earlier operating system, such as Microsoft Windows 98.
You have a mixed Terminal Services Licensing environment that has both Windows 2000 Server-based and Windows Server 2003-based license servers.
The Windows 2000 Server-based license servers do not have any permanent CALs available.
The Windows Server 2003-based license servers do have permanent CALs available.
In this scenario, the client computer does not receive a permanent Per Device client access license (CAL) from a Windows Server 2003-based license server.
Note You experience this problem intermittently. Sometimes, the client computer that has the earlier operating system installed may receive a permanent Per Device CAL from a Windows Server 2003-based license server.
There is a problem in the Windows Server 2003 version of the Lserver.exe program. This problem prevents Windows 2000 Server-based license servers from detecting a valid Per Device CAL that exists on a Windows Server 2003-based license server. Therefore, when a Windows 2000 Server-based license server has no permanent Per Device CALs available, this license server does not forward the CAL request to the Windows Server 2003-based license servers in the mixed Terminal Services environment.
In a mixed Terminal Services environment, the Windows 2000-based computer that is running Terminal Services may sometimes contact a Windows 2000 Server-based license server to obtain a Per Device CAL. In this situation, the client computer does not receive a permanent Per Device CAL even when a valid Per Device CAL exists on a Windows Server 2003-based license server. Instead, the client computer receives a temporary license from a Windows 2000 Server-based license server.
