Windows 2000 DNS
We have two domains, old.com and new.com. Old.com is and NT 4.0 domain and new.com is a Windows 2000 domain. We setup a DNS server in new.com to forward requests to old.com, but it is not forwarding requests properly. Is there anyother settings that we are missing in order to get the two servers talking properly? We are currently using forwarders and root hints.

Old.com is using a 192.168.x.x network and new.com is using a 10.9.x.x network. Do the two domains need to be trusting each other?

Darsyd,

Have you tried using two NIC's in the routing machine? One NIC is assigned a 192.168.x.x IP and the othe NIC is assigned a 10.9.x.x IP. Depending on the amount of traffic, you might need a pretty beefy machine. Then, clients that need to cross to the other network will have their default gateway set to the routing machines IP address (if the client is 192.x.x.x then the gateway will be the 192.x.x.x address of the routing machine, and the 10.x.x.x clients will have a 10.x.x.x IP (from the routing machine) as their gateway.

Another item to check is to make sure you have your reverse lookups setup properly on the DNS side. Is sound to me, though, that dual NIC's will help because the DNS server (router) needs to see both networks.

Good luck. Hope this helps.

CWilliams,
I don't think that that is the problem. We have a router in between the two subnets and the two subnets are seperate vlans and are being routed to the 192.x.x.x network. We can ping the dns server in old.com domain by ip address and fqdn.

You need to check the W2K machine's DNS zone. If you installed the machine as a root server (which is the default for a new AD when running DCPROMO) then you will have a . folder indicating a root server. Root servers cannot forward and the forward tab will be grey out. Check the MS Knowledge base for the Q article on how to remove the . folder. MS makes a .exe to do this correctly.
