    Hi all. If I connect to someone elses wireless network, how can I
    determine the computer name of the machine thats sharing out their
    connection?

    Why would you want to know.

  3. I'll assume Windoze XP Home. If you're using something different, it
    would be helpful if you would supply enough information to supply a
    reasonable answer.

    There's really no reason to need that info but if you insist, try
    running:
    Start -> run -> <enter>
    net view
    That should list all machines on the LAN with sharing enabled like
    this:

    C:\junk> view
    Server Name Remark
    --------------------------------------------------
    \\BLITHER PII-266
    \\CHOLESTEROL PIII-933
    \\MICRON PII-600
    \\AVARICE Bookkeeping
    The command completed successfully.

    If that fails, run:
    nbtstat -n
    which should give a bunch of NETBIOS machine names and workgroups.


    C:\junk> nbtstat -n
    Local Area Connection:
    Node IpAddress: [192.168.1.11] Scope Id: []
    NetBIOS Local Name Table
    Name Type Status
    ---------------------------------------------
    CHOLESTEROL <00> UNIQUE Registered
    CHOLESTEROL <20> UNIQUE Registered
    WORKGROUP <00> GROUP Registered
    WORKGROUP <1E> GROUP Registered


    C:\junk> nbtstat -r
    NetBIOS Names Resolution and Registration Stat
    ----------------------------------------------
    Resolved By Broadcast = 3
    Resolved By Name Server = 0
    Registered By Broadcast = 4
    Registered By Name Server = 0

    NetBIOS Names Resolved By Broadcast

    Hi all. If I connect to someone elses wireless network, how can I
    It might not be a computer, it could be a router, in fact it's most
    likely a router and besides, why would you want to know that?

    Easier to do:-

    ipconfig /all

    Then nbtstat -A <ip address of the default gateway address retrieved
    from above>

    Then just pick out the entry with the <00>

    The problem with NET VIEW is that it relies on the browser service which
    through it's basic operation is unreliable, particularly in a
    multiworkgroup/domain environment in the absence of WINS or cross
    related entries in LMHOSTS.

    Therefore it's far easier to just query the other machines netbios name
    table.

  6. In the router control panel :

    - admin area > local network > dhcp client table may tell you which
    computers have been assigned on the lan with active leases
    - wireless mac address > wireless client mac mac list will show you the
    current wireless clients

  7. That only works if the gateway is a Windoze machine. The original
    question implied that he's connecting to a computer, but it's more
    likely that it's really a router. I just tried it point to my
    BEFW11S4v4 gateway/router and got:

    C:\junk> nbtstat -A 192.168.1.1
    Local Area Connection:
    Node IpAddress: [192.168.1.11] Scope Id: []
    Host not found.
    True. Windoze browser service is marginal at best. I just love
    waiting 12 minutes for updates. You can bypass the browser service by
    simply pointing directly at the IP addresses. If sharing is enabled,
    even if there are no open shares, it will show the machine name. Of
    course, one needs to know the IP address of the target machine first.
    Start -> run -> \\192.168.1.1
    or
    Start -> run -> \\Netbios_name
    Yep, if it's a Windoze machine and not a router.

    Incidentally, I use a program called NBTSCAN to search blocks of IP's
    for machines.
    http://www.inetcat.org/software/nbtscan.html
    NMAP works, but it far more complex than I need for simply identifying
    machines.

    C:\blah> nbtscan 192.168.1.0/24
    Well, not very interesting because I tore apart my network last night
    and only have one machine online. Some of the other machines that
    have firewalls running appear invisible, which is good.

    That only works if the gateway is a Windoze machine. The original
    Certainly and I also stated in my first post that the machine sharing
    was most likely to be a router.

    I suspect the original question was one with malicous intent.
