    DNS all messed up

    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?

    Yes you could do that. Why have you come to the conclusion it's messed up?

    Because if I do nslookup for that server then it says it does not exist.

    Are the servers replicating OK?

    Do you have reverse lookup zones set up?

    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.

    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.
