unexpected_kernel_mode_trap

I have a W2K Server using Server 2000 and 3 WXP Pro computers on my home network. I upgraded to ver 1.28.277 and keep getting "unexpected_kernel_mode_trap" error on the server after I have turned the network on for approx 10 mins.

I uninstalled 1.28.277 and reinstalled the previous version and now I don't have any problems.

Also, before anyone asks, I did not install any new drivers or update any. The only item that changed on each computer is to update to ccleaner to ver. 1.28.277.

Any ideas?

Upload the latest dump file from C:\winnt\minidump (if it exists) somewhere and post a link to it - I will debug it for ya.
