Yes we did resolve the problem, and I forgot to post the resolution. It is a very
common misconfiguration of DNS services.
I can not find the e-mail I sent with instructions for the final resolution however
I will post it in brief.
DNS services are critical to the operation of Active Directory, when misconfigured
you will experience all sorts of trouble. The most common mistake that is made when
setting up DNS services on a windows domain is that the computers are allowed to
receive IP information (via DHCP) from a network router, rather than the windows
server. This is incorrect, because the network router will not provide the proper
DNS settings.
Every machine on the network must have the IP address of the windows domain controller
as their DNS server. This can be automatically configured if the DHCP server on
the windows server is enabled and the proper options are set. Ofcourse, other DHCP
servers, such as a router will have to be disabled.
Then, on the server, you will set a DNS server of 127.0.0.1, which tells it to point
back at itself. Now, go into your DNS server configuration and configure a DNS forwarder
that points back out to your network gateway, or external DNS server.
To sum things up, every client PC will make all of their DNS request from the server.
The server will also make all of its DNS request from itself. Any requests for
resources that are not on the local network, will be forwarded to an external DNS
server such as most network routers do now a days.
Without this setup you will experience VERY long login times, which is a tell tale
sign of incorrect DNS configuration.
Hope this helps.
