Active Directory: The specified domain either does not exist or could not be contacted. Hi guys! I am having issues with AD on one of my domain controllers. When I attempt to open AD it gives me the following message: “Naming Information cannot be located because: The specified domain either does not exist or could not be contacted. Contact your system administrator to verify that your domain is properly configured and is currently online.” My setup: I support 3 separate locations and have a Domain Controller at each location. Location A has the first DC that was setup and then Location B has a second one that works great but when I setup Location C this is what I get (error message). I am able to ping all of the other DC’s from each one of them. We run an external DNS server via MCI (local carrier). Has anyone had a similar issue with a DC running AD that could give suggestions? Thanks in advance…

You can't use a foreign dns server for AD. You have to have a ms dns server [should have two] and you put the isp's dns in the FORWARDERS tab [not to be confused with forward lookup zone] think about it for a moment. Ad needs to write dns entries. Do you know of any public dns server that would allow that? think arp poisoning. Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

Forgot to add that the wksts dns entries need to be the ms dns server Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.
