WIndows 2000 Server w/ 2 Nics DNS Problem
Posted on 2003-03-26
I have a windows 2000 server with 2 nics (2 networks) I have the Routing and remote access service performing Nat and using the DHCP relay agent to distribute private IP's to my internal dhcp client machines. This setup is working well and I am getting Internet access. Remember 1 nic is to my cable modem and the other nic is to a switch for my internal network.
Problem, when I join my windows 2k professional desktop to my server it goes well, but the DNS resolution is taking place from the ISP dns instead of my server's DNS. NSlookup is unable to locate the DNS server 192.168.0.1 I have checked all configurations and I believe it is my DNS server config. I only have mydomain.com in the forward lookup zone (no ".") whatsoever. I was having a problem prior to this and thought I fixed it by re-installing DNS on that server because I added a member server and was unable to run dcpromo because IT TOO couldnt find the DNS server. After removing and reinstalling the DNS server it fixed it. Here is the scary part. when I removed and stopped the dns server in my root server. My clients were still reaching the internet. It's obviously not paying my little DNS server on my root DC any mind. However my dcpromo worked yesterday so I thought all was well until I was unable to do a manage from AD to my client 2k pro pc. Error states unable to find client.mydomain.com .. I went to the client machine and ran a NSlookup and for sure, its not finding it. I ran nslookup to a legit Internet site and its using my ISP DNS. HELP!
