Cannot use search for files folders

Hello, I have no idea what happened. Im using windows 2000
professional and for some reason now when I click start-
search- files and folders nothing happens. No screen comes
up, no beeps, no errors- nothing. I even tried right
clicking on my hard drives and searching that way and
nothing happens. I just used this not 3 hours ago and it
worked fine. I have tried rebooting, but it still doesn't
work.

Any ideas how to fix this? Everything else works fine.

Thanks

Dwayne
