In what circumstances should I restore the MS SQL Server ‘master’ database?
You need to restore the `master’ database if you are doing the following: a. Rebuilding all your databases from scratch b. Changing any server-wide or database configuration options c. Added logins or other login security-related operations d. Created or removed logical backup devices e. Configured the server for distributed queries and remote procedure calls such as adding linked servers or remote logins. There is no need to restore your master database, if you just want to restore a user database.
