Computer shutsdown automatically...

I am working on a computer with windows 2000 and a dial up connection. When I try to connect to the internet with the dial up connection some error comes up that says something like this "Windows NT system authority has found an error and your computer will be shut down in 1:00 and it counts down and shuts down my computer automatically after the 1 minute is up.

At the bottom of the error message it says something about "lsass.exe"

Anyone have any idea what I can do to stop this from happening? or how to get rid of lsass.exe?
