You may experience any of the following symptoms:
Microsoft Windows Backup (Ntbackup.exe) incorrectly reports that the tape in your tape drive contains data that was created by you, but no files are listed on the media.
When you right-click the media listed on the Restore tab and click Catalog, you receive the following error message:
The next media required in the active family is not currently on-line. Please insert the media name of the media in the drive.
This problem occurs if you and another user have reused the same tape and if newer data, created by the other user, is actually present on the tape. Microsoft Windows Backup maintains backup catalogs on a per-user basis. This prevents you from viewing backups created by other backup operators.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft Windows 2000 Service Pack 4.
After you apply this hotfix, Microsoft Windows Backup maintains common backup catalogs for administrators and backup operators in a shared location (%SystemDrive%\Documents and Settings\All Users\Application Data\Microsoft\Windows NT\NTBackup\Catalogs51) so that all administrators and backup operators can view, catalog, or restore the information on a tape even if the tape has been reused by another backup operator. Note that if a user is not a backup operator, private catalogs are still maintained in your user profile (%SystemDrive%\Documents and Settings\user name\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\Catalogs). As a result, an administrator or backup operator may still experience the problems that are described in the "Symptoms" section of this article if a regular user overwrites a backup created by a backup operator or administrator.For additional information about how to obtain a hotfix for Windows 2000 Datacenter Server, click the article number below to view the article in the Microsoft Knowledge Base:
