SYMPTOMS
On a computer that is running Microsoft Windows 2000 Server with Service Pack 3 (SP3) or Microsoft Windows 2000 Server with Service Pack 4 (SP4), you may not be able to use Windows Backup to restore the system state.

Event Category: None
Event ID: 4097
User: N/A
Computer: <System_name>
Description: The application, ntbackup.exe, generated an application error. The error occurred on <date> @
This problem may occur if the following conditions occur in the order that is listed:
- You install the Cumulative Update for Microsoft RPC/DCOM on your computer.

- You use Windows Backup to perform a full backup of the computer, including the system state.
Note The system state includes the system files, the registry, Component Services, the Active Directory database, and the Certificate Services database. - You perform a new installation of Windows 2000.
Note A new installation is also known as a clean install. - You use Windows Backup to try to restore the system state. When you do this, you use the backup that you created by using Windows Backup.
CAUSE
This problem occurs because the Catsrvut.dll file and the Clbcatq.dll file do not match. This problem occurs because the Clbcatq.dll file is in use during the restore and cannot be replaced until after a reboot. As a result, the Catsrvut.dll file and the Clbcatq.dll file are not compatible when it comes time to restore the COM database.
WORKAROUND
To work around this behavior, use one of the following procedures:
- Restart the computer, and then try to restore the system state again. The problem does not occur when you perform the restore procedure for the second time.
- Install the Cumulative Update for Microsoft RPC/DCOM mentioned above, reboot the computer, and then perform the restore procedure. The restore will succeed without any failure because the Cumulative Update is already installed.
- Install the Cumulative Update for Microsoft RPC/DCOM after you have performed a new installation, and before you try to restore the system state.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
