I switched this server over from an iSCSI server to a NAS so it never has been a domain member before. No changes in the network and I don't see anything in the event viewer regarding this issue. I tried my domain admin account and it failed with the same error as the domain administrator account. Restoring is not an option since this server was never a domain machine since it was an iSCSI VMware datastore before this. I really do appreciate the suggestions. Thank you.
