How to recreate msdb for SBSMONITORING

Just follow the steps in the SBS 2008 Repair Guide:

Using SQL Server Management Studio and looking at the instance of SBSMONITORING it appears to have lost connection to the physical files for the system databases. The SBSMonitoring database is visible and accessible. The physical files do exist as I can see them using Windows Explorer.
I've tried running the SQL 2005 install again as detailed in this article http://technet.microsoft.com/en-us/library/dd560614(v=ws.10) but that fails because it's  already installed.
I suppose it's a repair I'm looking for.

There's really no need to repair the existing monitoring database... just recreate it (you would have to delete the old one first though).  If you note at the bottom of that article I suggested above there is a link to this article:

Yes, I tried that but it didn't rebuild or reconnect the system databases - probably just SBSMonitoring.

I'm not understanding what you mean by that last comment.

Sorry, not very clear.
When I connect to SBSMonitoring using Server Management Studio and then look at msdb under System Databases I would expect to be able to expand it to show tables, views etc. All I get in the SBSMonitoring instance is just msdb with no "+" sign next to it to expand.
Looking again I discover that the msdbdata.mdf and msdblog.ldf files aren't in the filesystem as I thought they were so I think it's these I need to recreate.

The key to fixing this problem was to restore the msdb mdf and ldf files from a new SQL instance. I had already run the recreate from http://blogs.technet.com/b/sbs/archive/2011/08/22/how-to-recreate-the-sbsmonitoring-database.aspx
Many thanks for the input
