    hi yall,
    i have 2 laptops running xp (1 home 1 pro), 1 laptop running vista premium, 1 desktop running xp pro. all connecting via wireless. i have a dhcp network (from broadband modem). all computers can ping and access each others shares via \\{ip address} but not \\{computername}. i have determined that all computers are master browsers.

    i cant seem to get them to do a proper election. netbios over dhcp is enabled. i tried netbius. neither worked.

    i moved the network from 1 location to another, no settings were changed, problem didnt exist there.

    does anyone have any ideas?????

    thanks

    On each computer, let's see this:

    Start, Run, CMD to open a command prompt:

    Type the following command:

    nbtstat -n

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    "i have determined that all computers are master browsers. "

    How was this done.

    To see what browse master each computer is using, download and run:
    http://www.onecomputerguy.com/software/browmon.exe

    Can you ping by computer name. If you can't get that far, then it is before any browsemaster problem.

    i found out that running this command would also tell me that it was the master browser or not by the presence of the last line .._MSBROWSE_. and through browstat status command on all machines.
    and as stated earlier i cant ping computer name, only ip.

    also node types on the computers are:

    laptop xp home: hybrid
    laptop xp pro: hybrid
    laptop vista: hybrid
    desktop xp pro: unknown (lol we have a winner ding ding ding)

    the vista laptop has cracked the shits and wont get a dhcp address. another problem entirely but ill solve that another day. manually configured is good enough for now.

    Again, since pinging by name does not involve browsing, you need to get that resolved first.

    But a quick way to test would be to turn of XP's ability to be a master browser.

    1. Start Regedit.
    2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters\
    3. Change MaintainServerList's value to to false.
    4. Reboot

    Then see if you can ping by name.

    Maybe 3rd party firewalls are preventing ping by name and even preventing a Master Browser election. Usually 3rd party firewalls have to be uninstalled cleanly or properly configured for LAN access. Sometime 'disable' or 'turn off' will work.

    Pick two of the XP machines and make sure the following services are running and show us ipconfig /all.

    Make sure the following services are running (Control Panel - Administrative Tools - Services):

    DHCP Client
    DNS Client
    Network Location Awareness
    Server
    TCP/IP NetBIOS Helper
    Workstation

    Start, Run, CMD, OK to open a command prompt:

    Type the following command:

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Those ipconfigs look perfectly fine to me. And you have all those services running. And can ping by IP address but not by name. I can think of only two things.

    1. Firewalls
    2. Weird router behavior.

    For (1) check again for firewalls, including ones that may have been uninstalled. Norton, McAfee, Zone Alarm and others have been known to not cleanly and completely uninstall, and result in problems that are practically undiagnosable. Symantic and others have cleanup programs or instructions on their web sites.

    For (2) reset the router to factory default settings and reconfigure it minimally (just enough to get internet access and maybe change the SSID and the login password. With everything off plug in modem first, then router, then boot the above two computers one at a time. Save the other two for a little later. Give the network 15 or 20 minutes to settle in and try ping by IP and ping by Computer Name again. If successful make sure file sharing is now working by name; then add the other XP; then add the Vista. If unsuccessful, you might try connecting two of the PCs via ethernet and see if that makes any difference.

    It can take DNS a while as well to know each computer's name and IP.
