HOW TO: Migrate a WINS Database from Windows NT 4 Server to Windows 2000 Server (300473)

SUMMARY

This step-by-step article describes how to install and configure Windows Internet Name Service (WINS) in Windows 2000 Server and how to migrate a WINS database from Windows NT 4.0 Server to Windows 2000 Server. By doing so, the Windows 2000 Server-based computer assumes the role of the WINS server and maintains the WINS database that Windows NT Server 4.0 previously held.

You can install WINS on either a member server or a domain controller. Microsoft highly recommends that the server has a single network card and is configured with a static IP address.

Move the WINS Database from Windows NT 4.0 Server to Windows 2000 Server

To move the WINS database from the Windows NT 4.0 Server computer to the Window 2000 Server computer:

1. Stop the WINS server on the Windows NT 4.0 Server computer. To do so:
   1. Click Start, and then click Run.
   2. In the Open box, type cmd, and then click OK.
   3. At the command prompt, type net stop wins, and then press ENTER.
   4. Type exit, and then press ENTER to quit the command prompt.
2. Stop the WINS server on the Windows 2000 Server computer. To do so:
   1. Click Start, and then click Run.
   2. In the Open box, type cmd, and then click OK.
   3. At the command prompt, type net stop wins, and then press ENTER.
   4. Type exit, and then press ENTER to quit the command prompt.
3. Copy the contents of the Winnt\System32\Wins folder on the Windows NT 4.0 Server computer to the Winnt\System32\Wins folder on the Windows 2000 Server computer. To do so:
   1. On the Windows NT 4.0 Server computer, start Windows Explorer.
   2. Locate the Winnt\System32\Wins folder.
   3. Copy the contents of the folder that you located in step 3b to the Winnt\System32\Wins folder on the Windows 2000 Server computer.
4. On the Windows 2000 Server computer, verify that the Winnt\System32 folder contains a copy of the Edb500.dll file.
   
   If it does not, copy the Edb500.dll file from the Winnt\System32\Dllcache folder to the Winnt\System32 folder. To do so:
   1. Start Windows Explorer and locate the Winnt\System32\Dllcache folder.
   2. Right-click the Edb500.dll file, and then click Copy.
   3. Locate the Winnt\System32 folder.
   4. On the Edit menu, click Paste.
5. Start the WINS server. To do so:
   1. Click Start, and then click Run.
   2. In the Open box, type cmd, and then click OK.
   3. At the command prompt, type net start wins, and then press ENTER.
      
      You receive a message that the WINS service cannot start. After that, the database is converted.
   4. Type exit, and then press ENTER to quit the command prompt.
6. Verify the consistency of the WINS database. To do so:
   1. Click Start, point to Programs, point to Administrative Tools, and then click WINS. The WINS snap-in opens.
   2. In the console tree, right-click the WINS server, and then click Verify Database Consistency.
   3. When you are prompted, click Yes to start the consistency verification operation.
      
      Note: Consistency verification can use a lot of resources when there is a large number of names or a large number of WINS servers. You may want to perform this operation during off-peak hours to minimize the effect on your WINS servers and network.
