When trying to run the server backup in the SBS2011 console after installing sp1 for SharePoint 2010 it was failing with the following error logged in application event logs
‘Volume Shadow Copy Service error: Failed resolving account spsearch with status 1376. Check connection to domain controller and VssAccessControl registry key.’
I found the solution on the SBS Blog it doesn’s appear to complete the PSConfig to update the SharePoint Database and one of the effects of this is
Without completing PSCONFIG, you might experience unexpected SharePoint search failures and all backups may stop working on the affected server.
To determine if this applies to your situation run an elevated SharePoint Management shell and when the shell opens type
(get-spserver $env:computername).NeedsUpgrade
If the result of this command is True then you need to complete the following steps
- Open an Administrative command prompt
- Change the directory to c:\program files\common files\microsoft shared\web server extensions\14\bin
- Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures
This process will take a while so just let it run it took about 10mins on my server.
