Unable to log into web site via sharepoint after moving DCs to a different segment of class "C" network

Hello folks,

I have been tasked to move our 2 domain controllers to a non-internet facing segment of our Class "C" network. We run SharePoint 2010 on our web server and once I have made the change, we are no longer able to login. Logon window just loops like a bad password error.

After the change is in place NSLookup resolves all server names and IPs. Remote desktop works across the network by name and IPs. DNS is registered, Webserver has DCs IPs listed for DNS. We just cannot log into the website.

Please help.
