Cname for GUID not created during DNS install

Discussion in 'DNS Server' started by Keith Rosenfeld, Sep 30, 2006.

  1. Just did a clean install of Server 2003R2. Added DNS and other roles in
    preparation for loading Exchange 2003.

    Ran DCDIAG and kept failing the first connectivity test. Error message said:
    "The host (GUID.msdcs.hc1.mydomain.biz) could not be resolved to an IP
    address. Check the DNS server, DHCP, server name, etc. Although the GUID
    DNS name (GUID.msdcs.hc1.mydomain.biz) couldn't be resolved, the server name
    (xxx.hc1.mydomain.biz) resolved to the IP address (x.x.x.x) and was pingable.
    Check that the IP address is registered correctly with the DNS server."

    I went into the DNS console and found that CNAME entry that links the GUID
    with the server name was not created during the install of DNS. I manually
    created the record and immediate passed DCDIAG.

    Ever see this before? Any idea if I missed something during install?

  2. This record is created by the netlogon service, not by DNS install. If the
    netlogon service did not create the record, restart the netlogon service and
    look for netlogon errors in the event log, and make sure the domain
    controller (as with all AD Domain members) uses only "the" DNS server(s)
    that have support for the AD domain in TCP/IP properties. No external or ISP
    DNS should be used in TCP/IP properties, on any AD domain member or DC.
