I have found that a "cleaner" way to back up NT4 is to use something like Veritas intelligent recovery. It's an option for BackupExec and you make 4 floppies and snapshot the server+data to tape.. it's like Ghost on steroids. If and when the server dies, you boot off the floppies which contain a stripped kernal + BE and drivers. Insert the tape and let it rip. Presto.. NT back with the config snapshoted. I have used this to rebuild a server from ground up in less then 1 hour.. beats fdisking, loading NT, loading drivers, load BE etc...etc...etc.
