TB64 Posted May 30, 2013 Posted May 30, 2013 We have 2 Dcs both have DNS, 1 is messed up. What is the best way to remove the DNS service and re setup from scratch. Is it by manage server remove DNS role?
Michael Posted May 30, 2013 Posted May 30, 2013 Yes you could do that. Why have you come to the conclusion it's messed up?
TB64 Posted May 30, 2013 Author Posted May 30, 2013 Because if I do nslookup for that server then it says it does not exist.
TB64 Posted May 30, 2013 Author Posted May 30, 2013 Ok I removed DNS re installed but it brought back all the old records, so its in the same state.
TB64 Posted May 30, 2013 Author Posted May 30, 2013 yes its when I type in the ip address of the server it can't find it, it does if i put in the server name.
psydii Posted May 30, 2013 Posted May 30, 2013 (edited) Are you sure that nslookup is using the DCs? I believe that nslookup will fall back to netbios name resolution if it doesn't get an answer from DNS. Edited May 30, 2013 by psydii
psydii Posted May 30, 2013 Posted May 30, 2013 DNS best practice: On your TCP/IP settings of DC1, have 127.0.0.1 set as the primary DNS server, and the ip of DC2 as the secondary. On your TCP/IP Settings of DC2 have 127.0.0.1 set as the primary DNS server, and the ip of DC1 as the secondary. For your clients/non-dc servers whether static tcpi/ip settings or in the DHCP Scope Options on your DHCP Server, have DC1 set as primary and DC2 as secondary DNS servers. Configure your DNS Servers to use either your ISP DNS, Google DNS or Open DNS as your DNS Forwarders. If your servers do not appear to be registered properly, check that their TCP/IP settings are correct and then issue the command ipconfig /registerdns at an elevated command prompt.
