I'm currently at work and the systems we use...are really old but that's besides the point. They are old school Dell OptiPlex GX1 PCs with P3 processors and Windows NT OS. Just recently i got an error that said the C:\\winnt\system32\lsass.exe was not responding or something of the sort. I wasn't able to get all the info since it restarted too fast. Anyone know what going on? This is happening to all the computers in the office building. Which range from around 100-250 PCs i'm sure.
