TS on SLES 10 -Windows XP Connection Failure

[Icewind_89]

Hello
My Problem is:
When I try to connect to my TS (SLES 10) the Authentification is no problem then the Window with the 2X Logo appears.
This window is followd by a black screen who disapears after a few seconds. In the Session Manager the session isn't terminated..

The Log from the Client on Windows XP shows the following lines:
