WORKAROUND

To work around this issue, use one the following methods.

Configure the Backup Account by Using Msdmback.vbs

At a command prompt, type the following commands and press ENTER after each command
cd /d "c:\program files\sharepoint portal server\bin" cscript.exe msdmback.vbs /a username password
where username and password are valid settings for an account with administrator permissions on your server. Alternatively, you can use a domain account by typing the user name with the domain\username syntax.
Close the command prompt.
Restart your server.

Delete the DefaultPluginAccount Registry Value

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.

Start the Registry Editor (Regedt32.exe).
Locate the DefaultPluginAccount value under the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Search\1.0\Gathering Manager
NOTE: The registry key is one path; it has been wrapped for readability.
On the Edit menu, click Delete, and then click Yes.
Quit the Registry Editor.
Restart your server.

MORE INFORMATION

The DefaultPluginAccount registry value does not to exist until you use the msdmback /a command to specify which account is used for backup and restore operations.

For example, if you type the following commands at a command prompt, you set the user account:

cd /d "c:\program files\sharepoint portal server\bin" cscript.exe msdmback.vbs /a username password

This registry value is read when MSSEARCH service is started. When there is a problem with this user account, the Msdmback.vbs utility cannot complete and returns an error.
