I'm running W2K Pro on a Dell Optiplex. I recently installed a new primary hard drive and a clean copy of W2K Pro. The only other installation was the Intel chipset from the Dell Resource CD. I keep getting a dialogue box with the following message: "The system process C:\WINNT\System32\lsass.exe terminated unexpectedly with status code 128." The system shuts down and restarts. Can anyone tell me what I need to fix, and how I need to fix it? (I'm a data person, not an IT pro. So, you need to walk me through it.) Thanks.
