Thanks for the replies.

So if a DB server totally dies and it is not recommended that the Master is restored on another machine then what would be the normal recovery procedure.

Install SQL on new machine

Apply any updates

Restore User databases from backups

Restore MSDB from old server from backup (to get jobs etc)???

but what about logins and any user objects in the Master database from the corrupt server? How would these be retrieved, or should these all be pre-scripted as part of the DR plan and these used in case of a disaster..thanks
