Good evening! Im trying to make a high availability environment on my work, in order to do that I setup a little lab installing 2 servers; one with WS 2008 R2 and the other with WS 2012 R2 (same as real environment but virtuals). The domain controllers and dns was installed successfully on both and replicates without problems
- Server 1 (primary), WS 2008 R2, IP=172.16.200.10/24, dns primary=172.16.200.20, secondary=loopback
- Server 2 (secondary), WS 2012 R2, IP=172.16.200.20/24, dns primary=172.16.200.10, secondary=loopback
I did not use AD integrated dns zone, instead primary/secondary zones were configured. The problem comes with clients, if I make a query to primary dns work well, when primary is shutdown I have no response from secondary even after a long wait,
ipconfig /flushdns does not work either nor rebooting. Am I doing some bad configuration?
I get a good response with commands
repadmin /showrepl and
dcdiag /test:dns /dnsbasic, it seems like no errors were found. Funny thing is when I use Linux i got a response from secondary dns server.
Thank you in advance.
