I started receiving an error message today after installing a new NIC. When I rebooted the server I received a message about a service not starting up. When I try to access AD I get a message of "Naming Information cannot be located because: The logon attempt failed. Contact your system administrator to verify that our domain is properly configured and is currently online." When I start Exchange 2007 I get the error message of "No Suitable Domain Controller was found in domain Foughty.Local." I only have one server, which is my DC, Exchange Server and Blackberry Enterprise Server." Any ideas?
