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:

This tape has been secured. You do not have the proper privileges.



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.



WORKAROUND
To work around this problem you can reinstall Windows NT or remove U.S. Service Pack 2 by using the Emergency Repair disk. Before choosing to use these workarounds, see the Status section below.



STATUS
Microsoft has confirmed this to be a problem in U.S. Service Pack 2 for Windows NT and Windows NT Advanced Server version 3.1. This problem was corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1.
