Backup Exec System Recovery and NTBackup keep failing

Hi All,

This is starting to drive me crazy, we have multiple servers running Windows 2003 r2 sp2 and Backup Exec System Recovery 8.5.  We generally use BESR as our primary restore method due to its speed and reliability during a failure.  The problem is its not too great with Exchange and SQL, so we generally use NT Backup as well to make sure we get a file backup of the Exchange Stores and SQL files.

As we have upgraded our servers to BESR 8.5 we have found that some of them continue to work in this setup with no faults but others start to have regular failures caused by VSS issues.

For example one site reports the following events every time that NT Backup is started:

Event Type:      Error
Event Source:      VSS
Event Category:      None
Event ID:      11
Date:            16/04/2009
Time:            09:25:35
User:            N/A
Description:
Volume Shadow Copy Service information: The COM Server with CLSID {790f2886-9889-4c99-8ef5-531add05d044} and name SW_PROV cannot be started. [0x8007007e]

Event Type:      Error
Event Source:      VSS
Event Category:      None
Event ID:      12292
Date:            16/04/2009
Time:            09:25:35
User:            N/A
Description:
Volume Shadow Copy Service error: Error creating the Shadow Copy Provider COM class with CLSID {790f2886-9889-4c99-8ef5-531add05d044} [0x8007007e].

I have another server that reports:

Event Type:      Error
Event Source:      VSS
Event Category:      None
Event ID:      10
Date:            16/04/2009
Time:            07:05:00
User:            N/A
Description:
Volume Shadow Copy Service information: The COM Server with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and name Coordinator cannot be started. Most likely the CPU is under heavy load. [0x80080005]

The only similarly between these servers is the fact they have both BESR 8.5 & NT Backup.
I have already installed all the updates for VSS and re-registered the relevant DLLs.

As you can understand this is getting rather annoying and I cannot find any answers ad could really do with a helping hand.

This seems to be an issue twith the "Symantec VSS Provider", Microsofts report on what they did was:
_______________________________________________
## We Took the backup of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers and deleted the 262b716e-bb23-41b5-aaef-e2c15e767167 (Symantec VSS provider).
 
## Took the backup of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\ and deleted the "Subscription".

If you are taking your backup on tape drives, format the drive before you take a new data. In my case it works fine - as I overwrite the new data to tape drive in a week cycle consisting 7 tapes for each day.

Both backups run to a large NAS else were in the building.

This problem was caused by a faulty NAS after changing the device our backup is now operational.

Sorry closed the wrong Question...
This issue is still ongoing but I have Microsoft looking into it as well.  As there does not currently seem to be an answer on Experts Exchange I will publish Microsofts answer to this question.
