I installed Services for Unix a little while ago and things have been somewhat okay. My server locked up once or twice but I blamed those shutdowns on myself even though I could not see that I did anything wrong. Today I tried to scan a document into CorelDraw that I have on my server. I use CorelDraw infrequently and this has worked for me in the past on W2K and now on W2K3. Today the server locked up. I rebooted and tried again. It locked up. Now I am pissed off! After some research and a few more reboots I finally located the culprit, nissvc, or otherwise known as Server for NIS. Task Manager showed it was consuming 30% to 100% of the cpu. I tried changing the settings back to the default settings but I could not seem to get rid of the problem. So I shut it down. Actually I shut down Server for NIS, Server for NFS, and the rest of servers in Services for Unix console. I don't use any of them except sftp and it is not listed.
