Question : Terminal Server - RDP Protocol

I have a Domain Controller with Terminal Server installed on
it. I also have a separate Citrix Server with thin clients
that connect via the ICA and RDP protocols.
Yesterday, I did a Windows Update on all my servers,
updating to SP4 as well as all the critical updates for
protection.(KB835732; KB828741; KB837001; KB830352;
Q828026)
My Domain Server runs Windows 2000 Server SP4 and my
Citrix Server runs Windows 2000 Server SP4 with Citrix
MetaFrame XPe SP3.  

Since the Windows Updates all thin clients using the RDP
protocol cannot connect, and the event log gives an error
Event ID 1004  "The Terminal Server cannot issue a client
license."  All clients connecting with ICA protocol work
fine. This all started the precise moment I updated my
Domain Controller, I have stopped and started the terminal
licensing services, and checked all necessary settings.

Do you know of a solution, it not, how can I roll back to
Service Pack 3, or the original settings.

Thanks

Johan

Answer : Terminal Server - RDP Protocol

simply rightclick the connection (in the context-menu you can activate/deactivate the protocol)

I don´t think the licensing-server and citrixserver has a communication-problem, because the ica-connection also requests a TSE-CAL.
