• Change the name of a protected computer and associate the existing replicas and recovery
points with the new computer name.
We recommend that you do not change the name of a protected computer. If you must change
the name of a protected computer, you must complete two tasks:
• Remove the data sources on the computer from protection (the old computer name).
• Protect the data source on the computer (the new computer name).
To rename a protected computer
1. Remove all members from protection groups.
If you retain the replicas and recovery points, the data remains accessible for
administrative recovery until you delete the replicas. However, it will not be accessible for
end-user recovery.
2. Uninstall the protection agent by using DPM Administrator Console on the DPM server.
3. Change the name of the computer.
4. Install a protection agent by using DPM Administrator Console on the DPM server.
5. Add the data sources to protection groups on the DPM server.
For information about tasks that involve protection agents and protection groups,
see DPM Help (http://go.microsoft.com/fwlink/?LinkId=102087).
Changing the Front-End Web Server
To protect a server farm on servers running Microsoft Windows SharePoint Services 3.0 or
Microsoft Office SharePoint Server 2007, you start the Windows SharePoint Services VSS Writer
service (WSS Writer service) and install the DPM protection agent on a single front-end Web
server. DPM uses this front-end Web server to perform backups.
The following procedure uses the example of a server farm with two front-end Web servers,
Server1 and Server2. DPM uses Server1 to protect the farm. You need to change the front-end
Web server that DPM uses to Server2 so that you can remove Server1 from the farm.
Note
If the front-end Web server that DPM uses to protect the farm is unavailable, use the
following procedure to change the front-end Web server by starting at step 4.
To change the front-end Web server that DPM uses to protect the farm
1. Stop the WSS Writer service on Server1 by running the following command at a
command prompt:
stsadm -o unregisterwsswriter
2. On Server1, open the Registry Editor and navigate to the following key:
HKLM\System\CCS\Services\VSS\VssAccessControl
