Application Hang

    We've recently installed Windows Server 2008 and are now experiencing some
    problems with application hangups.

    The server is a domain server with a few shared files and folders. No
    applications are installed on the server.

    Periodically, someone updating one of the shared files from a client PC will
    cause a lockup. The event viewer on the client PC shows Application Hang.
    There are no events showing on the server for the time of the "incident".
    All shares on the server lock at that time and the only way out is to reboot
    the server.


    Additional information that may or may not be related. Our router is acting
    as DHCP server for the entire LAN. The DHCP server on the domain server is
    disabled through services and unauthorized.

    Any suggestions as to what could be causing the lockups?

  2. Hello RR2,

    I would not use the DHCP form the router, do it the other way around and
    disable it, install the server as DHCP server and also use DNS on the Server
    not from the router, if so configured.

    Best regards

    That would be my desire, but I'm haveing problems there too. I tried
    changing to the server for DHCP service, but couldn't get to the internet.
    For some reason, the DHCP server on the domain server isn't passing the
    default gateway to the clients. Since our previous server (before the
    crash) was setup with the router serving DHCP, I left it that way from the
    beginning. The old server was an NT-4 server and all worked well.

  4. Hello RR2,

    Did you authorize the DHCP server and activate the scope? If the DHCP scope
    options are setup correctly with domain internal DNS server and default gateway,
    the router ip from the LAN run ipconfig /renew on a client or reboot it.
    It should get the correc tsettings from the DHCP server. Additional you have
    to configure the DNS server from the DC, which normally will be installed
    during promotion of the first DC, with a forwarder ip address. This ip is
    the DNS server from your ISP and has to be set on the server properties in
    the DNS management console under the forwarders tab. On all machines in the
    domain you have to use only the LAN internal DNS server no external/public
    ip address.

    Best regards

    Here's the steup I tried. I limited this to one test client when no one
    else was in the office so other logins were avoided.

    Server:
    DHCP service running and authorized.
    scope: 192.168.1.227 - 192.168.1.227 (so as to only issue one IP)

    IPv6 unchecked
    IPv4
    IPs
    192.168.1.2
    255.255.255.0
    192.168.1.1

    DNS
    192.168.1.2
    209.253.113.10
    209.253.113.18


    Router (IP is 192.168.1.1)
    DHCP disabled.

    Client
    Obtain IP address automatically
    Use following DNS
    192.168.1.2
    209.253.113.10
    209.253.113.18

    On client I reseased and then refreshed ipconfig. The correct DNS showed up
    under ipconfig /all, but default gateway was blank. No internet.
    I also ran the same routine with the DNS on the client set to automatic.

    I know I'm doing something wrong somewhere along the line.

  6. Hello RR2,

    For the scope, use more then one ip, make a range of 5 and when the ip is
    leased from the client, exclude the other ones.
    As said before remove the 209.253.113.10 and 209.253.113.18 from the DNS
    configuration on the NIC's and setup a forwarder as described.
    Please post your scope options also.

    Best regards

    Hi Meinolf,

    I really appreciate the info you're coming back with. As you may guess, my
    networking abilities are limited to hands-on learning.

    Please clarify the following points:

    remove the dns 209............... Is this from the server nic, the client,
    or both?

    "setup a forwarder" Please explain.

    Where do I exclude the unused IPs? I could probably stumble around and find
    it, but it's easier to ask and prove I'm stupid as opposed to locking
    everyone out and having them tell me.

    On all computers NIC'S in your domain.
    On the server open the DNS management console, go to Start, Run and type
    "dnsmgmt.msc" without the quotes. In the console add the server if not displayed.
    If you see the servername, mark it, rightclick and choose properties. On
    the opened window choose the FORWARDERS tab and here fill in the 209.x.x.x
    addresses, doesn't matter which order. If the options are greyed out, open
    the + and go to the Forward lookup zones, here you can see a "." zone (root
    zone, only used from DNS root servers), rightclick the "." and delete it.
    Then close the DNS management console and open it again. Now you can add
    the addresses to the FORWARDERS tab, it will not longer be greyed out.
    Open the DHCP console, choose your created scope and open the +. Here you
    can see Exclusions, scope options, leases. Rightclick Exclusions and choose
    add exclusion range or similar, on the popped up window you can either specify
    a range or a single ip address.

    Hello Meinolf,

    OK, here's where we stand.
    I've extended the scope to five IPs (227-232)
    No exclusion area listed even after refresh, so I skipped that part.

    209..... DNS listings removed from the server as well as the client.

    Forwarders were already set. Must have been picked up from the router.

    I did the ipconfig series (all, release, renew, all) on the client. Even
    rebooted the client.

    Still no internet.

    NOTE: I did not kill the DHCP service on the router as the rest of the
    company is still logged in.

  10. Hello RR2,

    Please post an unedited ipconfig /all from the client and the server. The
    Exclusions in DHCP you have to add by hand, will NOT be filled automatic,
    how to i posted before.
    Again, is the DHCP server authorized? In the DHCP console rightclick the
    server and check AUTHORIZE option. Also did you activate the scope?

    Best regards

  12. Hello RR2,

    For the exclusion i was rong sorry, rightclick Address Pool and choose New
    exclusion range. What is listed if you mark the scope options? You should
    see at least,006 DNS servers, 003 Router.

    Your domain name is only royalnet? Nothing with royalnet.local or something
    else?

    Best regards

    Correct, only "royalnet" for a name. Our previous domain under NT-4 was a
    single word, so I changed it slightly so as not to confuse the new from the
    old security hashes.

    the exclusions have been entered for 128-132

  14. Hello RR2,

    When it was NT4, did you upgrade or create a total new server? Unfortunal
    single label domain names should be avoided. Will not be a problem in your
    small network i hope, but if you think to grow you have to change it to royalnet.local
    or similar, do not use a real ending like .com or .net domain internal. Exchange
    2007 for example will not run with single label domain names.

    Again, please post the scope options from your DHCP server.

    Best regards

    Hello Meinolf,

    When the old server crashed, it required a new motherboard and CPU. NT-4
    and it wouldn't co-exist, so it was done as a clean install by a tech
    support guy as I felt it was over my head.

    I don't see us ever growing past what we have now (about 30 clients).
    We don't run anything on the server by way of application. I have our
    intranet posted there and quite a few shared folders so different people can
    get access to the same things.

    Cheers,

    Ron

  16. Hello RR2,

    Ok, but if you think about new software like exchange remember the problem
    with single label domain names. Back to DHCP, what about the client ipconfig
    without the DG ip address?

    Best regards

    Ha ha. it's the easy way out, but I'm retiring next spring and I don't
    foresee anything like that happening between now and then.

    "without DG ip address" I assume you mean to set the DNS to auto. If so,
    here it is:

    It's getting to be closing time here. I'll watch for any response at home,
    otherwise I'll pick this up on Monday. It you have anything for me to try,
    I'll come in on Sunday and run some options in peace and quiet.

    Hello Meinolf,

    I'm home now, but logged into the server.
    I hope this is what you were looking for by way of scope options:

    006DNS Servers Standard 192.168.1.126 None
    015 DNS Domain Name Standard royalnet None

    Regards,

    Yes, that 's what i look for and you have to set the option 003 for the router
    ip address, the Default gateway for the workstation.
