    Glad to hear that -- hope it stays that way.

    Well, the system zombied again today. It lasted a week and then froze. I'm
    going to create a backup and try the repair. I'm going to call Dell about
    the proper proceedure for installing SP1 for Win2k3 on the PowerEdge 2850.
    I've heard that it can be tricky.

    I'll keep this thread updated I guess, what do you suggest I do from here on
    out if the repair doesn't fix the problem?

    Well, "zombie"ing, whatever that means doesn't have
    much to do with DNS or even AD and logon requests.
    You may, but don't count on it if you don't get a response
    since old threads will eventually be deleted from my
    news storage -- on the other hand if it is still here, the
    group turns "red" when a new message is added since I
    am "watching" it.

    It would be odd if there is anything tricky about SP1
    for that specific machine -- although occasionally a
    BIOS update is required before loading a new version.

    What I mean is that the server stopped responding to login requests and
    people that had files open from thier network share lost the ability to
    access those files. I tried opening dnsmgmt.msc and got an Application
    Error Event log "Application Hang" Event ID 1002, "Hanging application
    mmc.exe, version 5.2.3790.0, hang module hungapp, version, hang
    address 0x00000000.".

    I don't know how this is related, but this morning we booted about 30
    machines simultaneously that are Deep Freeze clients. After booting, the
    machines, the server exhibited the same behaviour. We rebooted the server
    and then tried the same thing, booting a lab full of machines and it stopped
    responding again. The wierd thing is that I was able to login to the DC
    (which takes awhile when this happens) and open the dnsmgmt.msc o.k. but
    still no one could login and shared folders were inaccessable.

    What's a Deep Freeze Client?

    Those hang warning make me concerned for the DNS dll's etc.
    and would suggest a repair install is in order.

    Deep Freeze is made by Faronics - We use it on all of our
    clients. None of our servers run it. At any rate it essentially "freezes"
    the workstation's system state so you can give a user Admin on a box, if you
    wanted, and they can install stuff for a day. When the machine reboots, the
    system state is restored to the original snapshot. It is really handy in a
    lab environment. One feature of the administrator console allows us to
    control the clients and shutdown a bunch of machines at once or turn them
    all on at once.

    When we turn on a lab of 30 - 32 machines simultaneously (sends a wake on
    lan signal) the server freezes. So at least we are able to replicate the
    problem now. What is wierd is that it will also happen during the day when
    folks are coming in and out of the lab and not turning on very many machines
    at once.

    So there is a pattern and there isn't a pattern.
    I have two weeks to work on it in between semesters now. I have made a full
    backup and will do a repair this week as well as Service Pack 1.

    I can't perform a repair on the Dell PowerEdge 2850, when I put the Dell
    Supplied Windows 2003 CD in it does an automatic install without prompting

    I'm going to do SP1 and see what happens.

    Herb Martin Guest We use it on all of our
    You are likely running into a DESIGNED FEATURE (not
    a bug) due to the Deep Freeze mechanism. This is similar
    to using Ghost or any Backup scheme to restore a machine
    to a known state.

    After a week or so, the backup image will no longer 'know'
    the computer password on the domain (because one of it's
    invocations will have changed it and they expire within
    1-2 weeks usually.)

    Now the computer cannot authenticate itself, nor due to this
    it's user, on the domain. The computer account must be

    [The obsolete method is to unjoin/rejoin the computer from
    the domain.]

    Reset is accomplished by one of the included or support
    tools: AD User/Computers right-click, NetDom, NLTest,
    DSMod, ADSI script, etc.

    Try a real Windows 2003 CD of the same version.
    (e.g., Standard or Entprise server.)

    I think the problem may be solved with SP1. After installing on both DCs,
    we simultaneously booted 30 machines and no server crash. We then
    simultaneously booted 60 machines and no server crash. Thanks for your help
    on this. I will post a new question if the problem reoccurs once the
    students come back this summer. Here are the KB articles I found that
    appeared relevant to our problem and that were addressed in SP1:

    "Windows Server 2003 Service Pack 1 list of updates" - 824721

    "Clients cannot log on to domain controllers that are Windows Server
    2003-based DNS servers, and network interfaces that are not registered in
    DNS can still perform dynamic updates" - 832478

    "Windows Server 2003-Based Computer Becomes Unresponsive During Periods of
    High Server Use" - 822820
