  • Corrupt DNS Server 2K3

    Let me know if you need more info.
    I'm trying to give details on this issue without actually being at the server.

    I have 1 server that is heavily used by 25 users every day.
    Server2K3 / DNS Server / Active Directory Integrated / POP3 Service (No Internet)

    DNS is corrupt. Not sure how. In a new position at work and acquired this DNS mess.
    The nslookup command does not see the server name, but does come back with an IP.
    The DCDIAG and NETDIAG commands indicate DNS problems.
    I can post this info later. I don't have it with me now.

    Everything appears to be functional, although I am very concerned about possible problems with
    proper workstation DNS name resolution and AD integrated info.

    No workstations are showing in DNS at all. Forward and Reverse lookup zones had already been created,
    but I don't see a _tcp zone anywhere. Isn't it required to have a _tcp zone?
    DNS just doesn't look right to me.

    Installed the Support Tools from the Server2K3 CD.
    I have tried running: netdiag /fix and dcdiag commands with fix options.
    I've flushed DNS, registered DNS from cmd prompt at server.
    Stopped/Restarted the netlogon service etc...
    netdiag and dcdiag still report DNS issues.

    I need to know if I can delete/recreate the Forward and Reverse lookups zones without having to
    worry about re-adding the machines to the domain, or having to restore data from backups.

    This is what I would like to do:
    1) Delete the DNS zones.
    2) Use ipconfig /flushdns command.
    3) Recreate the DNS zones.
    4) Restart Net Logon service
    5)Use ipconfig /registerdns

    Is this feasible, without me having to worry too much about losing data or corrupting DNS?
    I'm trying to avoid having to touch each workstation, unless required.

    Please disregard this post. I am working on a possible work around.

      run netdiag and dcdiag and post the output here.
      DNS is most of the time easily to fix.
