Cannot Restore Backup After Upgrading to U.S. Service Pack 2

• Microsoft U.S. Service Pack 2 for Windows NT and Windows NT Advanced Server version 3.1

SYMPTOMS

If you create a backup tape and restrict the access to only the owner and administrative accounts, you cannot access (restore) the tape under U.S. Service Pack 2 from either the owner or administrative accounts. If you attempt to access the tape, the following error message appears:

CAUSE

Prior to U.S. Service Pack 2, the security key was compressed in ANSI. In U.S. Service Pack 2, the compression was switched to Unicode.
