SCCM 2007 & KB948109

We've got a single System Center Configuration Manager 2007 server running all of our SCCM roles, as well as running MS SQL 2005 Express Edition SP2. When we installed the latest MSSQL update, KB948109 , we found that it completely hosed the security on the SQL instance. It appears that this is a rather widespread problem, in generally it looks like this update is wroght with issues. Luckily, running SCCM's Repair Site wizard on the server followed by a reboot cleaned up the mess. The more you know.
