Can you tell us whether you are trying to do a manual backup or is this with the SBS backup? If this is with the SBS backup, then please post the full log.

Thanks for responding, I am having a SBS backup and I am getting this message with the dailly report. The error is just after the backup runs but the backup log file is fine. Below is the error message in the daily report from server:

MSSQL$MICROSOFT##SSEE Event ID 33002 09/09/2008 Access to table dbo.backupmediaset is blocked because the signature is not valid.

Even I am facing the same problem. I am running on Windows Internal Database, everything works fine, and the database can be accessed from SQL Management Studio Express 2005 or a command line query. Both the SP1 and SP2 patches fail to connect to the database. Can anyone please help.
