How we recovered from a Microsoft SQL 2005 suspect msdb database

I am not a MS SQL Server guru. Honestly, it is a “set it and forget it” technology for me. After our last patching episode, we ended up with a SQL Server Agent offline, and our msdb file was listed as suspect. Seems like there are 2 ways to recover from this. 1 restore a backup, or two recreate with this method. Since we had a backup from the night before, we started with this method.

1. First, we restored the msdb file from Symantec Backup Exec to another SQL server as a user database.  Since it was the middle of the day, and we could not take down the SQL server, we wanted to get a copy of the the MSDBData.mdf and MSDBlog.ldf files. This was the quickest way to do it.
2. We stopped the SQL server, moved the suspect msdb files aside, and placed the restored versions in the right place.
3. Started the SQL Server, and SQL Server Agent came back online. All seems happy
