CAUSE

This problem occurs because the SQL Server 2000 Virtual Device Interface (Sqlvdi.dll) is a 32-bit DLL. The 64-bit Volume Shadow Copy Service (VSS) writer that is included with the x64 edition of Windows Server 2003 requires an x64 edition of Sqlvdi.dll to work correctly.

RESOLUTION

To resolve this problem, download the hotfix that is mentioned in the following Microsoft Knowledge Base article:

913100 FIX: The MSDE writer is not included when you try to use the Vssadmin.exe tool to list subscribed volume shadow copy writers

Hotfix installation information

Currently, no automatic hotfix installer is available for this hotfix. Therefore, you must manually apply this hotfix. To do this, follow these steps:

Run the SQL2000-KB913100-v8.00.1101-x64-ENU.exe package to extract the following two files:
- x64\Sqlvdi.dll
- x86\Sqlvdi.dll
These files are extracted into the directory in which you run the SQL2000-KB913100-v8.00.1101-x64-ENU.exe package.
Copy the x86\Sqlvdi.dll file to the Drive:\Program Files (x86)\Microsoft SQL Server\80\COM directory.
Copy the x64\Sqlvdi.dll file to the Drive:\Program Files\Microsoft SQL Server\80\COM directory.

Note If this path does not exist, you must create this path.
Click Start, click Run, type cmd in the Open box, and then click OK.
Change the directory to the directory to which you copied the x86 version of the Sqlvdi.dll file.
Type the following command, and then press ENTER to register the x86 version of Sqlvdi.dll:

regsvr32 sqlvdi.dll
Change the directory to the directory to which you copied the x64 version of the Sqlvdi.dll file.
Type the following command, and then press ENTER to register the x64 version of Sqlvdi.dll:

regsvr32 sqlvdi.dll
Restart the following:
- The backup program
- Any instances of SQL Server 2000
- The VSS

Important

You must apply this hotfix after you install SQL Server 2000 Service Pack 4 (SP4) on any one or more instances of SQL Server.
You must apply both the x64 version and the x86 version of the Sqlvdi.dll file at the same time. The new SQL Server Virtual Device Interface (VDI) support that is included in this hotfix is not compatible with earlier x86 versions of Sqlvdi.dll.

If you run SQL Server 2000 in a cluster environment on a Windows Server 2003, Enterprise x64 Edition-based computer, you must also follow these steps:

Click Start, click Run, type Regedit, and then click OK.
Locate and then right-click the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSSQLServer
Click Export, and then save this registry subkey to a SQL1.reg file.
Locate and then right-click the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server
Click Export, and then save this registry subkey to a SQL2.reg file.
In Notepad, open the SQL1.reg file, and then follow these steps:
1. On the Edit menu, click Replace.
2. In the Find what box, type Wow6432Node\Microsoft.
3. In the Replace with box, type Microsoft.
4. Save the changes to the SQL1.reg file.
5. Exit Notepad.
Repeat step 6 for the SQL2.reg file.
Right-click each modified .reg file, click Merge, and then click Yes when you are prompted to add this information to the registry.
Restart the server.

WORKAROUND

To work around this problem, stop SQL Server 2000 before you perform a System State backup operation.
