The warnings may also reference the spfarm account.


SBS 2011 Standard Edition installs SharePoint 2010 Foundation in SharePoint farm mode. The accounts SharePoint farm and SharePoint search are used as service accounts for some of the SharePoint services. In order to be able to utilize the VSS writers, the accounts must be granted access to VSS. The accounts are added by SBS to the VssAccessControl registry key but the VSS service fails to locate the accounts. You can ignore the warnings. The warnings don't affect the operation of VSS. If you wish to remove the warnings, you can use the steps in the resolution section.


Use the following steps to work around the issue.

  1. In Active Directory Users and Computers, create a Domain Local Security Group named VSSRegistryGroup.

  2. Add SPFARM and SPSEARCH accounts to the VSSRegistryGroup Group.

  3. Run regedit.

  4. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VSS\VssAccessControl.

  5. Add DWORD value of DOMAIN\vssregistrygroup where domain is the netbios domainname (for example, CONTOSO\vssregistrygroup. The Domain name must be in all caps) set the value to 1

  6. Remove values for domain\spsearch and domain\spfarm.

  7. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VSS\diag.

  8. Right-click diag and go permissions, click Advanced and add VSSRegistrygroup group with Full Control.
