RE: [ActiveDir] Win 2003 DNS issues

No, our DCs arent multihomed.  Our ISPs DNS servers are set statically.  We have "Secure cache against pollution" enabled.  And we have "Do not use recursion" checked under the list of forwarder IPs.  We have forwarding on our child DCs to forward to our root DCs, and our root DCs forward to our ISP DNS.

Given what he described, I don’t think it’s EDNS0. EDNS0 is a problem, but I don’t think that’s what he is seeing here.

 

Russ, are your DCs multi-homed, by any chance? Is your ISP’s DNS server appearing anywhere in your DNS list, being served up by DHCP, perhaps? Have you also looked at the KB offered by Mark Parris?
