We upgraded from NT 3.51 to 4.0. Everything seemed to go fine; the server is up, the users can log on...but the server can't find its CD drive nor its tape drive. The server is a Compaq Proliant 5000; the tape drive is external and is a 15/30 gb DLT; the CD drive is internal. It finds the drivers (at least for the tape drive) okay. It just doesn't acknowledge there's a tape drive or CD connected.
