SCCM 2007 Backup stopped working?

Recently, our backup within SCCM 2007 R2 stopped working.  So, I applied SP2 which did what it was supposed to do by appending the server name correctly.  However, the backup still doesnt work and when trying to do a query in Service Manager we get " Error Communicating with the component".  Anyone seen this AFTER applying SP2?

The last entries in that log are from 2-24 which is when I think this broke.  Its a pretty big log, what should I be looking for?  It looks like it was successful until this date

i would like to check it for further errors. Could you post it?

I've collected some questions which you should check to make sure that these things are configure correctly:

- Can you check the if you can reach the SQL Server from Site Server via UNC Path?
- Can you access the SQL Servers registry from remote ?(Remote Registry Service)
- Is there maybe running another backup job at the same time with your SCCM backup? VSS can only handle one job at the same time.
- Is the Volume Shadow Copy Service running on the SQL Server?
- Is the Site Server's machine account memmber of the SQL sysadmin Group?
- Is the Site Server'S machine account member of the SQL Servers local administrators?
- Are you running the SQL Service under a service account context or with local system account?
If yes:
1. Check if Kerberos is enabled on the SQL Server with the following command
select auth_scheme from sys.dm_exec_connections where session_id=@@spid
2. Check if the SPN's are registerd successfully for the service account
--> setspn - L <ServiceAccountName>
Has to be twice. With and without SQL Port number (normally 1433)
