U-Tools: Unique Tools for Windows System Administrators

Old NT Service Packs

Q: Can I use UPromote with NT Service Pack 3 or earlier?

A: NT Service Pack 4 (released in 1998) changed the internal format of the password database. The general rule is that all domain controllers must run SP 4 or later. This is a well known issue with NT (KB Q197488). UPromote will work with earlier service packs, and it will warn you if it detects two servers with incompatible service packs.
