    PAWDC1 is the server you're trying to remove?

    You will need to run remove selected server while connected to (using
    connections, connect to server <someserver>) an active Domain Controller
    (one that works perfectly) either as a Domain Admin within the same
    domain as PAWDC1 or as an Enterprise Admin.

    I was under the impression that PAWDC1 no longer existed? Are you going
    to rebuild it after this? It won't be able to talk to the domain without
    some work, a rebuild is the neatest way.

    Okay, that's good then :) You were running the command with an
    Enterprise Admin account?
    There's nothing wrong with DNS, but DNS is very simple. Your problems
    lie in AD where you're trying to get DNS to store and replicate it's data.

    Your diagnostic reports earlier had a significant number of errors.
    Putting the forest into a state where it isn't continually upset carries
    high priority for me, with those there as well it becomes extremely
    difficult to pick out the real issue from the deluge of older errors.

  3. This looks a lot better. You had me worried for a sec, when I looked at the
    previous dcdiag.

    Run dcdiag on the other DCs, too. If clean, then sure, give it a shot now.

    That looks wonderful :)

    So where are we up to. ForestDNSZones is replicating properly? Does it
    still refuse to create DomainDNSZones?

    At the moment everything is pointing to the same DNS server (the current
    working version)?

    Can you manually verify whether or not
    c95ae251-3f01-4d4b-b996-d1c6252c0ac8._msdcs.hbrapp.hbr-inc.com exists
    (_msdcs folder)? If it does, which DC does it point to?

    And is it still troubled about the Domain Naming Master? Where is that
    hosted at the moment if you run "netdom query fsmo"?

  6. Are there any firewall rules blocking traffic between the DCs?

    Take 10.250.16.15 out of the IP configuration for now?

    Getting rid of the Kerberos failures is certainly a good thing.

    How are the Event Logs doing these days? Any errors being generated in
    Directory Service / DNS?

    This is going to be a stupid question.....what do you mean "Take
    10.250.16.15 out of the IP configuration for now"? Do you mean remove it
    from being a DNS server??

    I mean remove references to it from TCP/IP configuration (network
    adapter properties).
    Since the other DCs are fine, are we able to demote PAWDC?

    I would like to know if it still suffers from Event ID 482 after
    demotion (then ideally a rebuild) and promotion.

    Given that it needs to be able to modify that attribute to enlist the
    ForestDNSZones partition it does go a fair way to explaining why it's
    not had much luck.

    The issues with DNS replication stem from your problems in AD.
    Is VCServer online and happy?

  10. Actually it would, because the Schema and Config container replicate forest
    wide.

    I thought you were going to demote PAWDC2?

  11. You can leave those services on the server. It will just become a member
    server, and you will still be able to access files, etc. Just make sure you
    change the DNS address on it to another DC first, and not pointing to
    itself. DNS on it will be useless because the zone is AD integrated,
    therefore because it is no longer a DC, it will not load the AD integrated
    zone. No problem there, other than making sure no other machine is using it
    as a DNS server.

    Will you be re-promoting it?

    Ace

  12. How long did you wait before you re-promoted it?

    If you waited enough time to allow the information that removed DC is gone
    to replicate, then you should be fine.

    Are there any time issues or anything else in the event viewer?

    Are there any services disabled?

  13. Hmm, so there are time errors. When you look at the clock on this machine,
    and the clock on the PDC Emulator, how far off is the time compared to each
    other? Keep in mind, it can be no more than 5 minutes.

    Which machine is 10.250.16.10?

    If I'm reading this correctly, the time errors could be the root cause of
    all the problems. Just to double check (because this thread is so large that
    it's difficult to go back and read through it to double check), there are no
    firewalls blocks between the new DC and the other DCs, right?

    Follow the following procedure. Make sure theer are no firewall ports are
    blocked, and you have inbound UDP 123 allowed to go from the outside world
    to the DC holding the PDC Emulator role. Follow the procedure below first on
    the PDC Emulator (whcih will reset the time service), and then follow the
    section to set the time service on the newly promoted machine (where it says
    On Other DCs).

    Before you do that, read the following link to see if any of the poster's
    scenarios are similar to what you have going on.

    Configuring the time service on your PDC FSMO role holder
    by Ace Fekay, MCT, MCTS Exchange 2007, MCSE & MSCA 2003, MCSA Messaging
    Updated 7/12/2009
    ---

    To set the time service in an existing domain:

    On the DC with the PDCEmulator FSMO:

    w32tm /config /manualpeerlist:192.5.41.41 /syncfromflags:manual
    /reliable:yes /update
    net stop w32time
    net start w32time

    On other DCs (that are not the PDC Emulator):
    w32tm /config /syncfromflags:domhier /update
    net stop w32time
    net start w32time

    ---

    If you move the PDC Emulator to another DC:

    On the new PDCEmulator (where 'peers' is an Internet time source such as
    192.5.41.41):
    w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes
    /update

    On the old PDCEmulator:
    w32tm /config /syncfromflags:domhier /update

    After that run the following on both DCs:
    net stop w32time
    net start w32time

    ---

    The "peers" can be a text file, or direct input, allowing you to set the
    time source, either DNS name
    such as (time.windows.com, or an ip address for a reliable time source. I
    normally use 192.5.41.41.
    On your edge firewall, make sure UDP port 123 traffic is allowed inbound
    from the time source.

    Here you can find some time sources at this link:
    The pool.ntp.org project is a big virtual cluster of timeservers striving to
    provide reliable and easy to use NTP service for millions of clients without
    putting strain on the big popular timeservers.
    http://www.pool.ntp.org/

    If some domain machines have problems

    w32tm /config /syncfromflags:domhier /update

    After that run:
    net stop w32time
    net start w32time

  14. That's fine, you can use time.windows.com. I've been using, as well as many
    others, 192.5.41.41, and it's reliable. It's a gov time server in
    Washington, DC. There are others, as well. Here's a list of US Gov and other
    NIST time servers:

    article describes the Simple Network Time Protocol (SNTP) time servers that
    are available on the Internet.
    http://support.microsoft.com/kb/262680

    How to tell if UDP is blocked? Setup the time service on the PDC emulator as
    I've posted how, and look for any w32time errors in the event logs on the
    PDC emulator. If none, it's working. Either way, I think it would be
    beneficial to configure your time hierarchy for the forest.

  15. Sorry, I should have read this first before replying to the other one. This
    looks good. These are informational, and are not errors. This will insure
    all DCs are synched. Client machines will automatically look for the
    hierarchy to synch time.

  16. PAW2 was the one you just repromoted?

    These are indicative of DNS or replication issues. They can also be
    indicative of issues with DFS services (whether using it or not). Read

  19. Do you have a reverse zone created for all of your subnets?

    It's possible the replication scope error in the other post may be causing
    it.

    Good to hear the 1058's are gone.

  20. So if it can't contact the DNM, then no use rerunning dcpromo. Obviously
    there's a communication issue. It really smells like a firewall issue,
    unless the routers have the default MTU lowered from 1500, which will cause
    LDAP communication problems. Such MTUs lower than 1500 are usually on ADSL
    lines, but I don't rememeber you having such a line. I've seen some VPN
    routers with altered MTUs that caused problems. I had one customer years ago
    with a SonicWall that after an IOS upgrade, AD replication took a dive. It
    took me two days to figure out what happened when I finally asked what
    occured prior to the replication issue, which was when the customer told me
    they had upgraded one firewall. Ouch! We wound putting on the old image, and
    replication kicked off with no problems.

    Check all of your routers and VPNs, please.

    Also, run portquery on each DC between each DC to make sure all ports are
    responding.
