    Hello all,

    I have a problem seeing a Win XP Pro PC from other PCs on the network.

    Here is my setup:

    Time Warner (Roadrunner cable) connected to:

    LinkSys 4-port router, connected to:

    P4 running Win XP Pro acting as a server (running IIS 5.0), P3 running Win
    98, and a 486SX2 running Windows For Workgroups 3.11.
    The Sever runs just fine.

    In Network Neighborhood, From the P4, I can see the P3 & 486. From the P3,
    I can see the P3 and the 486. From the 486, I can see the 486 and the P3.

    All of the disks have been shared correctly.

    I have even disabled the Windows Firewall on the P4. I still can't see the
    P4.

    Any suggestions, hints, etc as to where to look?

    Thanks in advance.

    Ted

    Thanks for replying Bob.

    I can ping all of the PCs using the IP address.

    I can ping the 486 & the P3 using the name, but the ping for the P4 returns
    the wrong IP address (I feel).

    For instance:

    The 486 is ted3 and 192.168.1.101.

    The P3 is ted2 and 192.168.1.104

    The P4 is ted1 and 192.168.1.103

    The ping for ted1 returns the IP address 192.168.1.100 instead of
    192.168.1.103 (like I think it should).

    As you can tell, I am at a loss as to what to do next.

    Good morning Ted.
    When you ping ted1 and tou get the wrong ip address, you are pinging the
    computer name ?
    It seems a problem with names resolution.
    I suggest two tests :
    a) create (if you don't have it already) a share on ted1 and try, from ted3
    and ted2 to open \\ted1\sharename
    b) Maybe you have an host with 192.168.1.100 on your net that is not ted1 ?
    If you are sure that ted1 is 192.168.1.103 and you get response from
    192.168.1.100, try to shut ted1 and see if pinging 192.168.1.100 still works.

    Let me know

    Hello Ted.
    I thought ted1 was an host on your network.
    It's a remote computer ?
    Anyway, I would try to "isolate" the connection to ted1 and see if the
    "wrong" ip still responds.

    Hi Fabrizio.

    I guess I was in error about the wrong IP addr.

    ted1 (win xp pro) is 192.168.1.100, also acts as a server for my website.

    ted2 (win 98) is 192.168.1.104.

    ted3 (wfw 3.11) is 192.168.1.101.

    I can ping all names & address from all pcs. This works.

    I had to add netbios to ted1, and all pcs show up in the network
    neighborhood workgroup now.

    ted2 & ted3 only show each other in network neighborhood.

    I can map drive to all pcs from ted1.

    I cannot map drive to ted1 from ted2 or ted3.

    I tried to disable the firewall on ted1, but it made no difference.

    I am slowly but surely running out of ideas. I'm sure it is a simple
    setting that I'm missing, but danged if I can figure it out.

    Thanks for any help.

    If ted1 hosts your website, it will have a public IP. Make sure that
    Netbios over TCP/IP is disabled on that interface, and enabled on the
    192.168.1.100 interface.

    Thanks for the reply, Bill.

    My brain, at this stage of the game, is pure mush.

    How do I go about making the changes that you suggest?

    You do it from the TCP/IP properties for each NIC. Try the advanced
    TCP/IP settings, WINS tab.

    If it is enabled on more than one interface in a machine, it can cause
    problems with browsing the machine (because there is more than one IP for
    the machine name).

    Hi Bill. I looked at what you suggested, but I only have 1 NIC.

    I guess I should give you the whole story.

    Roadrunner cable modem to:
    Linksys 4-port router. (port forwarding 80 to 80 & 21 to 21, both to
    192.168.1.100)
    Using No-IP as a managed Dynamic DNS.
    All 3 PCs connected to the router.
    Ted1(192.168.1.100) = Win XP Pro using IIS 5.1 for the server.
    Ted2(192.168.1.102) = Win 98 (ip address has changed).
    Ted3(192.168.1.103) = WFW 3.11 with TCP/IP and NetBEUI added.

    When I ping ted1 from ted1, I get: (notice the Reply from IP address)

    Pinging TED1 [::1] with 32 bytes of data:
    Reply from ::1: time<1ms
    Reply from ::1: time<1ms
    Reply from ::1: time<1ms
    Reply from ::1: time<1ms
    Ping statistics for ::1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

    When I ping ted2 & 3 from ted1, I get the actual IP address.
    When I ping all 3 from ted2 or ted3, I get the actual IP address.

    All 3 pcs show up in the Network Neighborhood on ted1.
    only ted2 & ted3 show up on ted2 and ted3.

    File and Printer sharing is active on all 3 pcs.

    TCP/IP and Net BEUI is active on all 3 pcs.

    Firewall and AVG are disabled(temporarily) ted1.
    AVG and ZoneAlarm are disabled(temporarily) on ted2.
    There is nothing to disable on ted3.

    The server on ted1 is OK. I have shortcuts set up with the actual
    http://www.theob2.retrospect address.

    As I said previously, I am at my wits end, and don't know where to turn.

    Sorry for being so long-winded.

    Ted

    If you really have netbeui running on the non-XP machines, I would
    remove it. Netbeui and Netbt (netbios over TCP/IP) are quite separate and
    build different browse lists. (Netbeui has been phased out and is not
    installed by default in XP). So it looks like ted1 is building a Netbt
    browse list which it uses but the others don't. One of the others(probably
    ted2) is building a browse list based on netbeui, and this is the browse
    list that ted2 and ted3 are using.

    Hi Bill, Thanks for replying.

    I removed netbios on the non xp machines, It really threw my network for a
    loop, I reinstalled netbios and everything back to normal, except I still
    can't see the xp machine. the sp maching is Win XP Pro SP2. I wonder if
    SP2 didn't do something.

    Are we talking about the same thing? Do you understand the difference
    between Netbeui and Netbt (which is Netbios over TCP/IP)? Netbeui is the old
    IBM/Microsoft Lanmanager version of Netbios which does not use TCP/IP. It
    was the standard in DOS/Win3.x days and also used by W9x machines which
    didn't have TCP/IP installed. Because of the almost universal adoption of
    TCP/IP for networking, Netbeui is being phased out. Netbeui is not routable
    so is useless in a routed network which has ensured its demise. XP does not
    have Netbeui installed by default. And as I said earlier, Netbeui and Netbt
    are not compatible as far as browsing in concerned. They operate
    independently (which incidently doubles the broadcast traffic on the LAN).

    Disabling netbios altogether will certainly kill browsing!
