    Registration of DNS records failed: The RPC server is unavailable

    Hi;



    Environment:

    2003 Active Directory (Domain Functional Level is 2000 Mixed)

    3 Domain Controllers, each running active directory integrated DNS

    Domain members are mostly Windows 2003 Servers (WEB and Standard edition)

    All Domain members with the exception of Domain Controllers have multiple
    NICs installed.



    Problem:

    Some machines on the network do not register with DNS. When I try to
    register them manually by running "ipconfig /registerdns" I get the
    following error "Registration of DNS records failed: The RPC server is
    unavailable". I have confirmed physical connectivity to all domain
    controllers, I can copy files to and from the domain controllers, I have no
    problems logging into the domain. Everything seems to be working properly
    otherwise.



    Thanks for your help

    RPC traffic may know where to go based on the machine being multihomed. You
    can do things like adjust the binding order of the NICs so that the NIC
    facing the LAN containing your DCs/DNS servers is on top thereby directing
    your RPC traffic automatically in that direction first. RPC traffic will
    try the NIC bound first in the network stack I believe.

    Re: Registration of DNS records failed: The RPC server is unavailable

    Hi Todd;

    That's not it. I disabled all interfaces except for the one facing the
    Domain Controllers and tried re-registering... no luck. Any other ideas?

    Thanks
    Paul

    Other possible causes:
    1) DNS resolution problem. Look at the DNS configuration for Win2000 and
    above. If you rule out name resolution, try mapping a drive to a share on
    the target computer, and then try the operation again.
    2) RPC services not running on target machine
    3) TCP/IP NetBIOS Helper service not running on target machine
    4) Firewall blocking RPC ports in between the source and target machine

    Re: Registration of DNS records failed: The RPC server is unavailable

    Hi Todd;

    I was able to resolve the issue. Machines on which the DHCP Client service
    was disabled and stopped couldn't register wth DNS. Machines on which the
    DHCP Client service was running had no issues. That was it.

    Paul

    I should have thought of that. :-) Glad you got it sorted.
