SYMPTOMS
A Microsoft Windows Server 2003-based server that has Terminal Server enabled and that is located in a forest cannot obtain a license from a Terminal Server license server that is located in a different forest when those forests are connected by an external trust.

Note External trusts only support NTLM authentication. External trusts are also known as "down-level trusts" or "Microsoft Windows NT Server 4.0 trusts."

CAUSE
This problem occurs because Terminal Server cannot obtain a license when NTLM is used for authentication.
