Shared network resources cannot accessible after a while

    We got a Win2003 DC and 30 XP Pros at office. Users share disks & printers.
    But we have a weird problem, after a while (sometime 30 minutes, another time
    1 hour, it's not clear, maybe never) users cannot access these resources (folders,
    printers, etc) or access delayed.

    For example you browse \\userPC\c$, when you click a folder, explorer window
    freezes for a while (say 30 seconds) then the files listed at once. When you open
    a file, Word freezes for a while, when you save, waits again and you look the hourglass.

    When you try to print something it doesn't print, even you cannot examine printer properties.

    I've discovered a way to fix this; closing user's (which has got problem / not the remote one's) session.
    When you log-in again, everything comes back, now you may print or open what you want... For a while...



    I've pinged and no problem. Overall, It's not TCP related problem. I can browse files thru Internet Explorer
    at http://userPC/files (if there is a webserver) or I can connect remote machine via Remote Desktop. When
    I got problem at browsing remote files (\\UserPC\c$) I open Remote Desktop to remote machine then browse
    my own files (\\MyOwnPC\c$) there and I transfer files between remote and my machine without any trouble.


    Sometime a password login box appears when I couldn't connect to \\UserPC\c$.
    My pc should remember the user/pass but It asks me again and never accepts the pass
    even I type the right pass. I type a different doman user/pass and say remember it.
    Then everything is ok again, till login box appears next time. I switch user/pass on every turn.



    These are 30 pc with different configs. Firewalls are disabled. Antivirus doesn't matter.
    A new installed XP or old one no matter.


    It looks like RPC related but I'm not sure and I don't know any way to diagnose the problem.
    It's totally random thing. I have no clue, no reason...

  2. Maybe OT, but can I ask why you're sharing workstation resources when you've
    got a domain and a server? You really ought to have *all* your data on the
    server(s) and you should be using network printers you can share & manage at
    the server. I would get rid of all local shares and clean this up - you've
    got a very decentralized network right now and that really defeats the
    purpose of having a server.

    There is a limit of 10 concurrent connections on an XP machine.
    It may well be that you are exceeding that limit, and that closing a
    user's session and then starting again is (just) giving you enough spare
    connections.
    I believe the default session timeout is 15 minutes.

    I'm the admin and I browse every folder : )
    Put webserver something, download and place a setup file
    on user's desktop, etc.

    OK I'm gonna simplify my question; imagine only shared printers.
    Managers blame on me when they cannot print a page.

    Maybe, but a manager does nothing on his laptop and he cannot print either : )
    He only runs MSN Messenger, IE and opens a Word doc from shared folder
    on domain controller. When he couldn't print something he calls me : ) or : (


    May I increase that 10 limit? I think a registry setting could change it... I did it
    for IE before...

  6. I don't use shared printers on workstations, either. If a printer needs to
    be used by multiple users, it is a networked printer and is shared from the
    server.

    At least users map a folder as drive on DC. as Z:
    Same problem occurs time after time. User logs off then logs on.
    Not a comfortable solution, it's only annoying workout.

    I've checked, NET CONFIG SERVER and it displayed the sessions then I just remembered
    I did set timeout value as 1 min to make server much responsive and it worked because
    a dialog box never appeared which says "Maximum connections blah blah..."

    In my case there is no more dialog box...

  9. You haven't answered my questions. Stop sharing local resources. Use login
    scripts to control drive mappings (and use /persistent:no if you use a batch
    file with net use commands). It's really impossible to help you with the
    information given and the setup you've got, I'm afraid.

  10. Please see my reply. You're trying to put band-aids on what is a bad
    configuration. Rather than wasting time on it, correct the setup so
    everything is shared from the server and users have permissions only to what
    they are supposed to access.

  11. Hello Nime,

    I must agree with Lanwench that this is not a centralized environment and
    makes it difficult to support. It would be much easier on you as the
    administrator, if you centralized everything so there is only one place to
    make any changes, such as the server. Right now as it appears, you are
    administering all the workstations individually for individually shared
    printers and folders. This is difficult and cumbersome.

    Also some of the connectivity issues can be based on mis-configured AD DNS
    environment. To better help in this area and to see if it is a problem,
    please post an unedited ipconfig /all from your DC and of a workstation.
    This will give us a better idea of your configuration and AD environment.

  12. I disagree. His problem would simply not exist if he properly configured his
    network. I don't get paid to give people the answers they want in here -
    heck, I don't get paid at all. I give them the best answer I can based on
    many years of experience in this field. Whether they take it or not is up to
    them.

    I must have missed your own response to him....did you type it in an
    invisible font? ;-)

    I think my network is pretty centralized, users only access a public folder on domain controller,
    plus share a few printers, of course... We got strict user groups/permissions, no worries.

    You know, \\user\c$ is administrative share at all... which I've sampled here...


    I don't know the problem or any way to diagnose, that's much worst : (

  16. Hello Nime,

    Your users machine use the wrong DNS servers on the NIC. This will the clients
    kick off from the shares. Domain internal use only the domain DNS servers,
    remove the 195.175.39.40
    and 195.175.39.39 from the users machine and configure them as FORWARDER
    in the DNS server properties in the DNS management console.

    Also i fully agree with Lanwench about the setup itself.

    Best regards

    Meinolf Weber

    My own machine uses only one DNS...


    A few things:

    * I run \\userPC\c$ and wait for 30 seconds and a login dialog appears. I cancel and re-run \\userPC\c$
    now dialog box appears immediately.

    * If I type IP, instead, it will open immediately.

    * If I type \\anotherPC\c$ it will open immediately.

    * If I type different user/pass, it will open immediately.


    Would I focus on 'remembering names&passwords' ? Looks like Windows cannot remember passes
    or something like that... If it was DNS it couldn't connect when I replaced the user/pass...

    OK, the 'backup' DNS are there because of 'webserver+dns server' maybe shut down...

  19. With the current configuration (and misconfiguration) of AD and your network
    it is very difficult to offer any further advice. Sorry.

    Yes, and others agreed with me that his network is misconfigured.
