    Hi, I was wondering if anyone here has had a similar problem and
    worked through it.

    I have a Belkin 802.11b wireless router, with 4 wired Ethernet ports
    on the back. I have desktop computer wired into the router, while I
    have a laptop computer that connects wirelessly. Both computers run
    Windows XP Home, and can access the Internet great, but I haven't been
    able to get file sharing to work 100%. The wired computer can view the
    files of the laptop, but the laptop cannot view anything on the
    desktop. Here's what I have tried:

    Going to My Network Places, and clicking 'View workgroup computers'
    (Both computers have the same workgroup name). When I do this from the
    laptop, I get an error message saying that "You may not have
    permission to use this resource" and "Windows cannot find the network

    Typing '\\Dell' in the address bar (Dell is the name of the wired
    computer). This gets me another error message: "Windows cannot find

    I believe that I have opened all the ports necessary (TCP 129 and 445,
    UDP 137 and 138) in my firewalls.

    Any help would be greatly appreciated. Thanks!

    What I have found that sometimes works when you dont know what else to do is
    Select a folder on your desktop and add it to sharing, you will then get
    some windows that open to configure sharing.
    Just tell it to share with the other PCs and wallllloh
    it starts working.
    Of course if it doesnt work then, make sure file and print sharing is
    selected correctly in the adapter settings.

    Check the Windows firewall settings on the wired computer. Looks like a
    firewall problem. If you are using Zone Zlarm, check that it recognizes the
    network as a trusted zone.

    I tried your suggestion, but the configuration wizard didn't pop up,
    probably because I had gone through it previously. On the subject of
    the adapter settings:

    I went to the Network Connection properties from the control panel,
    and saw that "File and Printer Sharing for Microsoft Networks" was
    checked on the laptop with a white background, but on the wired
    computer it is checked with a grey background. Doesn't that usually
    mean that some, but not all components have been installed. I tried to
    find a way to install the other components, but I couldn't find one.
    Could this be the problem?

    Thanks for the suggestion, but I had turned off all firewalls

    If WEP is enabled on the wireless NIC, then you may have a problem
    communicating wire and wireless due to the NIC protocol being used. If
    Netbeui is the protocol, then un-install it off the NIC(s) on the machines.
    You can use NWlink as the protocol on the NIC(s) or just leave Netbeui off
    the NIC.

    I run with the following on the NIC(s):

    1) Client for MS Networks
    2) F & P S for MS Networks
    3) QoS Packet Scheduler
    4) Internet Protocol (TCP/IP)

    I use to run with NWlink but found that I didn't need it.

  6. You also need TCP port 139.

    Make sure "Use Netbios over TCP" and "Register this connection's
    addresses in DNS" are both enabled on your connections. The settings
    are per connection, so if your wireless uses USB or PCMCIA you'll need
    to check the settings individually for each slot or port you want to
    be able to use.

    Make sure the computer browser service is running on all machines. It
    is sensitive to firewall settings and shuts itself off if it doesn't
    like something.

    I have a similar problem ... I completely lost the ability to browse
    my network when I installed SP2 on my WinXP machines (I have 3 running
    XPpro, 1 XPhome and 1 Win2K - 2 are wired and 3 are wireless). I can
    connect the shares using IP addresses and can resolve names statically
    by editing the hosts file on each machine but dynamic name resolution
    no longer works on any of them.

    I have no answer to it as yet.
