Appendix I: Database Maintenance
In order to keep your WSUS server functioning correctly, you should have a maintenance plan that includes re-indexing the database on a regular basis, preferably at least once a month.
The WsusDBMaintenance script (http://go.microsoft.com/fwlink/?LinkId=87027) allows you to re-index any version of the WSUS database, either SQL Server or Windows Internal Database.
If you are using Windows Internal Database, you will need to use the sqlcmd utility. For more information about the sqlcmd utility, see sqlcmd Utility (http://go.microsoft.com/fwlink/?LinkId=81183).
To use this script with Windows Internal Database, you should run the following command:
sqlcmd -S np:\\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query –i <scriptLocation>\WsusDBMaintenance.sql
where <scriptLocation> is the directory where you have copied the WsusDBMaintenance script.
