Hi I maintain a windows 2008 server that is configured on a domain with about 20+ client computers. The problem I am having is that I am trying to use OpenDNS as a website blocker for all the computers on the domain, the problem however is this:
Currently the IPv4 properties on the server are configured to "Detect Automatically" and the internet works on the server and the client computers but the OpenDNS doesnt block any of the websites it should. When I configure IPv4 to what it should be with the IP pointing back to the server ip 172.17.248.10, the subnet being 255.255.255.0, the gateway being 172.17.248.1, and then the dns being made to point to 172.17.248.10, the internet stops working for all the computers. This of course is how our other servers in other buildings are set up (different ip's of course) and those servers control the clients just fine.
The only warning is under dns which is error event id 4515 "The zone was previously loaded from the directory partition domaindnszones. but another copy of the zone has been found in directory partition forestdnszones. the dns server will ignore this new copy of the zone." I went through with what I normally do to fix that problem by deleting the two forward lookup zones in the dns settings to reset them to default. _msdcs."domain name" and "domain name" itself, and their replications are both looking at the right place now. "_msdcs.domain name" to all dns servers in the forest, and the "domain name" to all dns servers in the domain.
But that still doesnt fix the problem with not having the internet work when the ipv4 is configured to what the other servers are like. We have tried creating a forwarder that goes strait to the ip address comcast gave us and even tried to use that ip address as the dns ip in ipv4 properties.
Has anyone had this problem before? I have the ipconfig /all from a client comp and also the server if this would help.
thanks, Matt
