Help with OpenDNS

[Kristi2k]

I am attempting to get OpenDNS and my networks internal DNS to play nice together. I am trying to get a few computers in our lab to use OpenDNS for external internet sites and to use our internal DNS for internal intranet requests / SMB requests.

I have tried to set OpenDNS as the primary DNS, our internal to secondary and set NetBIOS to register over TCPIP which allows me to browse to \\computer just fine with OpenDNS has primary.

But, if I attempt to load an intranet site, OpenDNS cannot find it because it's not asking the internal secondary DNS setting.

What am I doing wrong? Thanks in advance.

Setup open dns as the forwarders. You need to make sure you have a reverse zone operating correctly on your local dns. Also, you need to disable the typo correction. I know it's a nice feature, but it breaks some local queries. Trust me, I fubar'd our DNS with it a while back 😱

When the DHCP leases came up for renewal 100 thin clients couldn't find servers, it sucked haha. I still use them, just as I stated above. MUCH faster than our ISP servers, the phishing filter actually works for the spam we get, and being able to see domain stats is nice. Plus we have two redundant net connections (different ISP's) so it makes life easy without having to use diff servers.

Primary and secondary servers don't work that way (I presume yuo mean in the end host config). You need a dns server internally that all of your clients point at, that dns server can use OpenDNS as it's upstream forwarder.

Even as a forwader the typo correction breaks local dns.

I thought it went without saying that the local dns had to serve the local zone, you can't (and shouldn't) rely on wins.

I was afraid I had to set up DNS forwarding- which is not a big deal but I was hoping I could test this on a per computer basis.

Any other suggestions as a work around?
