Hi,
I have two sites main and dr. i have created additional domain controllers in dr site. in each site we have 4 domain controllers running on windows 2008 r2. when i try to nslookup from dr domain controllers to our Domain name, it gives me two times "Time out for 2S" and after that it properly shows me the IP addresses of the servers of my domain. I need to investigate why the RTO is coming. i am attaching the nslookup and ipconfig snapshots.
I disabled ipv6 from registry. all is working through normal ping and there is PTR for the server in DNS. Appreciate if anyone please guide.
thanks in advance
