Computers not talking to each other

    Hello all

    I'm fairly new to this forum, and a complete newbie when it comes to networking.

    And I seem to have a problem.

    I am running 2 laptop computers at home - one is running via an ethernet cable into my lovely WAG54G gateway (work provided it for VPN connection to company servers so I can't really change this) and the other is connecting wirelessly through a Linksys WPC54G card.

    Both are operating on Windows XP Professional and I have used the setting up a network wizard on both PC's

    I have given each computer a different name and used the MSHOME workgroup name.

    The problem is this - the wired computer in the office can see and access files stored on my wireless laptop, but although the laptop computer can see the office computer in view workgroup computers, when I try and access any files I get an error message saying:

    "Computer name" is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

    The network path was not found.

    Please can anyone help me - I've tried wiring the laptop into the WAG using ethernet rather than wireless but I'm still getting the same response.

    any ideas?

    Best wishes

    Steve

    On the PC you are trying to access have set up the drive or folder as a shared resource.

    You can tell if a drive is shared by an upturned hand cupping the drive icon when you use my computer or windows explorer.

    Yes, both PC's are showing that the relevant drives are able to be shared.

    This is general checklist for sharing files between PCs in a peer to peer network. There can be other reasons but I think most people new to networking and finding sharing a problem will find the answer somewhere in this checklist.

    These checks are all essential for sharing to work with TCP/IP.
    - All PCs have TCP/IP installed.
    - All PCs have Netbios over TCP/IP enabled (only needed if pre XP PCs used).
    - All PCs have the same workgroup.
    - All PCs have a unique computer name.
    - ALL PCs have network shares defined.
    - ALL NICS are on the same subnet (e.g. IP 192.168.0.* subnet mask 255.255.255.0).
    - MS Client and file & printer sharing are checked on each NIC.
    - All NICs have their node type = anything except p-node (peer to peer, or point-point). Check at cmd prompt with Ipconfig /all (XP/W2K) or winipcfg (W9X).
    - XP's ICF firewall is permanently disabled. (Only for pre XP SP2).
    - All 3rd party firewalls are disabled, uninstalled and deleted (until connection is working).

    Allow 15 mins after rebooting a PC for that PC to appear in the workgroup, or for it to see all other PCs.

    If all the above checked out and still a problem check these:
    Other ideas:
    - Realtek cards have been known to be a problem with IRQ conflicts. Move the Realtek card to another PCI slot.
    - Check your Services are Started on all PCs: Workstation, Server, TCP/IP Netbios helper, Computer Browser.
    - You only need TCP/IP. NWLink NetBIOS, NWLink IPX/SPX/NetBIOS Compatible Transport Protocol ->are not needed and can confuse things. Remove them.
    - XP gives access to its shares via the Net Guest Account. (Note, not the same as the local guest account which should be off). Check Net Guest Account is enabled:
    At command prompt:
    >Net user guest
    Should return a line with 'Acount active yes'.

    Check XP Security policies:
    - Access this computer from the network: add guest
    - Deny logon locally: remove guest
    - Network access:Sharing and security model... -> Guest only
    - Deny access to this computer from the network-> check Guest is not here.
