Hi, I got runtime error of "missing or corrupted system32hal.dll", http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xpehelp/htm /xeconhaldllismissingorcorrupt.asp said I should remve and then delete "HAL", HAL is not a component I can see in db, so I guess I should do with the component containing hal.dll. How can I know which component contains hal.dll? Thanks, Peter
