    Im on a 2003 domain with xp clients and i am not able to connect to some pc's
    via Network neighborhood or just \\computername, i get the "\\computer name
    not accessible. might not have permissions blah, blah blah. The network path
    was not found. With 90% of the othere computer i can access just fine. I can
    ping computer name and ip just fine.

    i already disabled the simple file sharing, and disabled the firewall and
    unjoined domain, deleted pc and rejoined and still cant access the computer.

    Any suggestions would be appreciated.

  2. What's the common factor between all the computers that you can't connect
    to?

    Are all the computers on the same subnet?

    Thanks,
    Oliver

    within the past month or so.

  4. Common factor, they are laptops. Some Sony some Dell. Joined to the domain
    Network Neighbourhood relies on the Computer Browser service to display
    NetBIOS computer names. The Computer Broswer service can take upwards of 15
    minutes to identify new names.

    How much time elapses between when the laptops are placed on the network,
    and when you search for their names? Do the laptops EVER show up?

    Also, make sure they aren't configured to disable NetBIOS. This can be done
    manually, or via DHCP. Go to the WINS tab in the Local Area Connection
    interface.

    Also, if the laptops are connected wirelessly, make sure you don't have any
    filters or firewall (local or on the AP/Router) that are blocking NetBIOS
    traffic.

    Do you get an error message, or timout message of some sort?

    If you don't get one via Network N., open a command prompt and type:

    net use x: \\computernam\c$

    use an administrator username and password, if prompted. What error do you
    get, if any?

    Dominick,

    I've seen this sometimes because of Winsock corruption. You can do the
    following:

    RESOLUTION
    To resolve this issue, follow these steps.

    Warning Serious problems might occur if you modify the registry incorrectly
    by using Registry Editor or by using another method. These problems might
    require that you reinstall your operating system. Microsoft cannot guarantee
    that these problems can be solved. Modify the registry at your own risk.

    1. On a good known working XP client Click Start, and then click Run.
    2. In the Open box, type Regedit, and then press ENTER.
    3. Navigate to the following registry key:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
    4. On the Registry menu, click Export Registry File.
    5. In the File name box, type the name of winsock and save to your desktop.
    6. Repeat steps 3 through 5 for the following registry key:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2

    7. On the not working client Delete the following keys from the registry:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2

    8. Copy the saved registry keys from the desktop of the known working
    client to the desktop of the not working client and double-click each of them
    to re-install the winsock and winsock2 registry entries, then reboot.

    Hopefully this helps.

    Ok, its getting there. Now when in Network Neighborhood they still get access
    error. But i figured out that once i access the good machine from the bad
    machine via network neighborhood then the good machine can access to bad
    machine. Hope that didn't confuse you.

    Dominick,

    Okay, on the bad machines, it sounds like there is some firewall or Norton
    product blocking these connections. Can you run msconfig and click the
    Services tab and check the hide all Microsoft services then disable all the
    other services temporarily and reboot, then try the connection again.

    This will eliminate some other product blocking this sharing capability.

    Patrick,

    Thanks for a response.

    I had the windows firewall service disable for about a week. I did do you
    suggestion by uncheckin all the other services, including symantec AV, and
    VPN. Unfortunately it still does the same thing.

    Computer a = bad computer
    Computer b = good computer

    computer b see computer a in NN(network Neighborhood), computer b dbl clicks
    on computer a and gets access error.

    Computer a see computer b in NN, computer a dbl clicks on computer b and im
    in.

    Now that the connection has been made, computer b can now access computer a
    for a short perio of time.

    Not sure how this all relates, it may be a WINS/NETBIOS issue but i am at a
    loss here. Any more suggestions??

    Thanks,
    Dominick

  13. can computer "B" always ping computer "A" by IP, or does this only work
    AFTER computer "A" communicates with computer "B", as you described above?

    if so, wait for the connectivity to drop again, then try pinging by FQDN
    (host.domain.com), using the same sequence. Does this work?

    computer B has no problem ever pinging computer a, either by ip or computer
    name even if they wont connect.

    So i go to compter a, and ping computer b it works and i can connect. Wierd.

    Its like computer b cannot initiate the communication first.

  15. Are you using DNS, WINS, or both?

  17. I'm making as assumption a bit quickly here, but I'm willing to bet it's
    related to WINS.

    First, I hate WINS and never ever use it. I haven't used it since W2K cam
    out... If you can (and there are very few reasons why you can't these days),
    just get rid of it. It's a piece of junk, and it always breaks.

    Second, let's try removing WINS from the picture temporarily. If you can,
    take a test laptop and assign it a static IP, then have the interface
    register the IP with the DNS server. DO NOT give it any WINS addresses.

    Test and let me know what happens.

    so here is what i did, i stopped and disabled my wins service, and took it
    out of the dhcp scope option. I will let the machines refresh and see what

    Ok, so its been about 24 hours and same thing. Can ping from b but cant
    access a. Once a pings b, then b can access a. Any more suggestions??

  20. what is your network topology? Are all the computer on the same subnet or
    are they split up somehow? Do you use layer 2 or layer 3 switches? Where is
    the DC, in relation to all your computers (same subnet, different subnet)?
