Administrator Credentials Fail on Primary Server

I have the system account as part of the administrator account on the Domain.

I'll run a test to see if I can get a partial backup.  Will know more later today, and will know for sure in the morning, just have had several backups fail in the last week.  I was able to logon to the System account for BE 2012, and as I said before, all other servers and workstation have no problem testing with the backup system account, just the primary.
