NW2004 -> DISP+WORK.EXE doesn't start

Hi,

I installed NW2004 SP11. Everything worked fine. When I start the sap system only the msg_server process is running but not the disp+work process. What might be the reason for this and how can it be solved?

System Settings:

Win XP

Java: Java 2 Runtime Environment, STandard Edition (build 1.5.0_22-b03)

Cheers,

Michael
