Veeam backup service failing to start

[somoa]

Hi

Came in today and found the Veeam service had stopped with no backups happening. Looks like it was in middle of a backup copy job when this occurred.

When trying to start the service the following error comes up.
After restart the server the service was able to start.

Anyone know what may cause this to happen?
I am guessing something lost access somewhere bit not sure what or how.

Service cannot be started. System.Exception: Failed to create desktop VeeamBackupServiceDesktop (ERROR_ACCESS_DENIED)
at Veeam.Backup.Common.WinAPIWrappers.CWinDesktop.Create(String name, Int32 heapSizeKb)
at Veeam.Backup.ServiceLib.CVbEnvironment.InitDesktop()
at Veeam.Backup.Service.CVeeamBackupSvc.OnStart(String[] args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

Sounds like a permission problem.
Did you check under which user the service is started? Did the credentials change for that user? Is it a local user or ad user. Is there anything else found in event logging.

Also, this is not a support forum, did you open a ticket with support? If so please add the ticket number to the post.

Found some timeouts in logs.

antivirus was cause of this as it crashed the service.

Hi Somoa,

Great that you found the solution!
There is a KB that lists all exclusions for AV etc.
