We have 2 servers

1 x Domain Controler, GC, DNS, DHCP etc

1 x Exchange & File Server

I can no longer create users or mailboxes on the Exchange Server. Both servers running Server 2008 R2 Enterprise.

Attached is a screenshot of the error i am getting in the event log on the domain controller.

 Error
DCDIAG also throws up errors when run on the DC/GC.
