it appears that win2k SP4 has a lot of problems... my thought would be to do a repair install or if possible somehow remove SP4 until the bugs are fixed.

info about the bugs in SP4 can be found here: http://www.winnetmag.com/Article/ArticleID/39644/39644.html

Try doing this

Right-click "my computer"
go to properties
go to advanced
go to settings under "startup and recovery"
and uncheck "automatically restart"

Check to see if you get any error message.. Post back with that

can you go inside safe mode ? press F8 when you reboot the machine , go to safe mode and remove service pack 4 ..

then reboot and check if it is fine

Looks like you need to have a bootdisk to start booting your OS cos you donot have the CD>

Hi there!  I had that same issue occure to me when I tried to upgrade one of my computers to SP4.  I check the Knowledge base and didn't find any answers there, so I just booted into safe mode, and went to the control panel (start/settings/control panel), and then went to unistall  software, uninstalled the sp, and got back to the original configuration.  I haven't discovered yet how to install that sp, so I'll probably just upgrade to W2K3 shortly....
