I have a test 2008 box setup running active directory and DNS. When I run a query against DNS from my workstation (not part of the 2008 domain) the request times out.
I've done my best to research the issue and I found that it might be related to IPv6, so I unchecked IPv6 on the server adapters and also made the registry entry to disable IPv6. Furthermore I've gone into DNS and deleted out any IPv6 references...still when I query DNS I get a timeout.
When I query DNS from the server itself, it responds appropriately. It seems like the query from my machine isn't authorized but the same thing happened when I joined a laptop to the domain to test.
Problem identified and solved. The network team enabled DNS spoofing filters on the main switch which prevents DNS queries from traversing the main switch UNLESS the DNS servers have been identified
