Terminal Services

Hi,
I installed terminal services on my 2000 advanced server. I also installed the client on a computer(win 2000prof)… When ever I try to connnect from the client, my server reboots. On the server I get the blue screen.. On the blue screen it say’s the following: unexpected_kernel_mode_trap and then the server reboots…..
Any reason why this would happen?
I’m new to terminal services.
Thank’s in advance…
