DNS Timeouts

Hello, I have replaced a server which was our primary dns on our network.  When I preform a nslookup to www.google.com I get results back immediately.  When I use www.msn.com and other sites I get a timeout see below.  I have validated the ISP's ip and their DNS settings but can't determine why some site have a hard time with resolution.  What is next to first make sure my dns is working ok and then what after that to deal with the ISP.  The ISP I am sure is going to say they aren't having a problem but I want to be able to do something to show what the issue is.  Any help is appreciated.

As a note, I have two DNS servers.  Server 1 has Server 2 (the other dns) setup as its first DNS entry and vice versa for the other server.  When I am on the server I get the same results but the other server is noted as timing out.


C:\Users\administrator>nslookup www.msn.com
Server:  xx.xx.ad
Address:  172.16.75.20

DNS request timed out.
    timeout was 2 seconds.

Well, first thing, I'm fairly certain that your first DNS server in TCPIP on a DNS server should its own IP.  Second, make sure that you have forwarders in the DNS setup to go to the ISP DNS servers.

I'm wondering if you used 8.8.8.8 or 8.8.4.4 (Google DNS) for DNS instead of the ISP DNS servers and that is somehow causing issues.

Side note - forwarders are not the same as CONDITIONAL forwarders.  Do NOT set those up unless you need them for a specific domain reason.

Thanks Tim, I had an internal DNS as the forwarder (not going to work).  Once I changed it to the ISP's dns it worked great. Thanks!
