Hello,
I am performing the backup of my DC (2008R2) with veeam (latest) and this warning appear in event viewer:

Volume Shadow Copy Service error: Failed resolving account SYSTEM with status 1376. Check connection to domain controller and VssAccessControl registry key

I already checked the regisrty:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\VssAccessControl but only NT Authority\\NetworkService is listed there.

My backup Job

Guest OS credentials: account which is member od domain admin groups

Could you plese help me clear out these warnings ?

Thanks and regards,
MK

Hi, it would be best to work with support on that, and have them research this (webex might be required). Thanks.
