Considerations for Rebuilding the master Database
Updated: 14 April 2006
When damaged, the master database must be rebuilt if:
A current backup of master is not available.
A backup of master exists, but it cannot be restored because the instance of Microsoft SQL Server cannot start.
|If you are using the full recovery model for msdb, which is recommended, before rebuilding master, you should try taking a tail-log backup of msdb. For more information, see Tail-Log Backups.|
In SQL Server 2005, the Rebuildm.exe program has been discontinued. For information on how to rebuild master, see How to: Install SQL Server 2005 from the Command Prompt.
|Rebuilding the master database installs all system databases to their initial location. If you have moved one or more system databases to a different location, you must move the databases again. For more information about moving system databases, see Moving System Databases.|
