256986 Description of the Microsoft Windows Registry



SUMMARY
If you require a fast process for disaster recovery when a critical WINS server stops working, Microsoft recommends the following procedure. You must follow this procedure before the WINS server stops working.



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

 Make sure there is a valid backup of your critical WINS server database. Also, save the WINS Partners registry key from the critical WINS server. This registry key contains the Push/Pull partner configuration. Save the Partners key from this registry location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Partners

 Install a backup WINS server that is running parallel with the critical WINS server. Set up WINS replication between the critical WINS server and the backup WINS server.

If the critical WINS server stops working, use these steps:  Rename and change the IP address from the backup WINS server to match the critical WINS server. Reboot the backup WINS server and stop the WINS service.</li> Restore the WINS Partners registry key from the critical WINS server to the backup WINS server's registry. Locate this key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Partners

</li> Click the Partners key, click Registry, and then click Restore.</li> Type the path where the file is located.</li> Start the WINS service on the Backup WINS server. At this point the backup WINS server will have the same replication partner configuration as the critical WINS server.</li> Force replication of the backup Wins server with all of its partners. At this point WINS will be fully functional.</li></ol>
