I have a little problem that I don’t understand at all. My brother has a laptop, a dell with win 2000 and a DSL. Everytime he goes online, or as its DSL whenever the line is plugged in the computer shuts down and re-boots. He gets an error saying that lsass.exe is shutting down or re-starting the system and a countdown. Anyone have an idea what this could be. A virus, scumware or perhaps a problem with his net provider?
