Secondary DNS will not answer
Posted on 2007-12-05
I have set up two servers. 192.168.10.1 as primary, and 192.168.10.2 as secondary. I get no errors on any of my tests, but once I take the primary DNS server off line, I cannot surf the web nor do any of test hosted sites (through IIS on 192.168.10.1) come up. I have connectivity only when the primary name server is up. Isn't everything supposed to fall back on the secondary name server?
(DNSReports shows everything perfect, except that I have open DNS servers, and that they will do recursive lookups. But I cannot lock them down, since if I do I can't get on the Net from that machine. All my updates fail, etc.)
But anyways, any ideas where to look or how to fix this secondary DNS not doing it's share of the work here, will be greatly appreciated.
