So this is wierd...

We have some older IBM NetVistas running Windows 2000 with 256mb RAM, so they're not that fast, but as workstations they've done ok...until the last update.

I recently ran Windows Update on them and installed the lastest update that came out recently, and now it's screwed them up. Not just one of them either, so it's a fairly consistent issue. After the update, it takes an unusually long time for a user to log in, then once finally logged in, it blue screens for a bit, then finally loads the desktop. This means a LONG wait anytime someone wants to use one of these boxes.

What's really strange is that once logged in, Ctrl-Alt-Del will not work. You can hit those keys all day long, and nothing will happen. It also takes an exceptionally long time to log out, and sometimes it will simply ignore logout commands; you have to manually turn the computer off to get out!

This does not occur until the latest Windows Update is installed. Prior to that all was well on all of these machines.

So has anyone else encountered this? What in the world could be the problem?
