FRS/DNS/RPC after joining 2003 Servers on 2000 domain

Discussion in 'DNS Server' started by Dennis Procopio, Jun 11, 2007.

  1. I added 2 new 2003 domain controllers to our domain, leaving 2 existing 2000
    servers as DC's until flaws and dependencies are identified. One of the 2003
    DC's (DC3) has been made an AD-Integrated DNS server, and the other (DC4) has
    inherited the WINS and DHCP services as I moved them from one of the 2000
    servers (DC2). DNS is also running on DC1 (also a 2000 server).

    One of the 2000 domain controllers (DC2) seems to be losing communication
    with the new DNS server (DC3). It can ping it one minute, and the next can't
    even resolve it's fqdn. When I added the 2003 servers I moved all FSMO roles
    to DC3. When doing a dcdiag on the entire site , DC3 reports back errors in
    the system log with event id 0x00000457. I don't see anything weird with the
    other domain controllers. DC3 reports event id 2088 for source domain
    controller DC2. DC2 also complains about not locating the global catalog
    when trying to use AD Users and Computers. I've also seen errors about RPC
    and DNS but cannot seem to locate them right now. I did have to make a
    registry adjustment about a month or more back on the rpcprotocol portion of
    the dns server in the registry because of the flaw in MS DNS that
    the problem?

    I'd like to be sure that DC3 has a healthy AD & DNS installation before
    demoting the 2000 servers. Any help on completing this would be awesome.

  2. Read inline please.

    You should make all DCs DNS servers and Global Catalogs. For best
    redundancy, each site should have two of each.

  3. Okay. All are GC's but not DNS servers, I'll do that next.
