    I have 6 computers at home, all running Windows XP with SP3 and the latest updates.
    All the computers are connected to the internet wirelessly (802.11 a/b cards) except one computer which is connected directly with a cable to the DSL modem/router (The model is ASUS AM604G).

    All computers' Workgroup are set to WORKGROUP

    In the Wireless Network Connection I configured each computer with a unique IP address. For example:

    IP address: 10.0.0.2
    Subnet Mask: 255.0.0.0
    Default Gateway: 10.0.0.138
    Preferred DNS Server: 10.0.0.138

    In each computer I shared drive C and also both of our printers which are connected via USB.

    So it appears I followed all the steps to create a home network, but still I can't access the other computer when I go to My Network Places, and also when I type in "Run" \\10.0.0.6 for example, I get this message: "The Network Path Was Not Found".

    How can solve this problem?

    I have another problem that might be related. In the main computer which is connected directly with a cable to the DSL modem/router, there is no possibility to change the IP, because after I change the properties of Local Area Connection and give unique IP, I click OK, and when I check the TCP/IP settings again all the properties return to the previous state of "Obtain an IP Address Automatically".
    Through ipconfig it tells me that my computer's IP is 10.0.0.7

    I would really appreciate your help!

    Tom

    First off, let's do this to eliminate any stack issues.


    TCP/IP stack repair options for use with Windows XP with SP2/SP3.

    Start, Run, CMD to open a command prompt:

    In the command prompt window that opens, type type the following commands:

    Note: Type only the text in bold for the following commands.

    Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

    Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

    Reboot the machine.



    Next, here are some network debugging steps, go through until you run into a problem.

    Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.

    Hold the Windows key and press R, then type CMD to open a command prompt.

    In the command prompt window that opens, type type the following commands:

    PING each remote computer by IP address, and if successful, PING by name. Open a command prompt as described above and type.

    PING <ip address>
    or
    PING <computer name>

    Where:
    <ip address> - is the x.x.x.x IP address
    <computer name> - is the computer name

    A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.

    Note: You can obtain the IP address and computer name of a computer by opening a command prompt (DOS window) and typing IPCONFIG /ALL. This should work for any Windows version. The IPCONFIG /ALL display will provide a wealth of useful information for debugging your network connection.

    Check your Services are Started on all PCs:
    • COM+ Event System (for WZC issues)
    • Computer Browser
    • DHCP Client
    • DNS Client
    • Network Connections
    • Network Location Awareness
    • Remote Procedure Call (RPC)
    • Server
    • TCP/IP Netbios helper
    • Wireless Zero Configuration (XP wireless configurations)
    • WLAN AutoConfig (Vista wireless configurations)
    • Workstation

    Note: You can check the services in Control Panel, Administrative Tools, Services.

    All of these services should be started, and their startup type should be automatic.

    If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.


    All computers should be in the same workgroup for computer browsing to function properly. File & Print Sharing has to be enabled on any computer you wish to share files or printers from. You also need to actually share the resource in question from My Computer, right click on the drive/printer/folder, and select sharing.

    If you encounter difficulties accessing computers that are visible in Network Places (Network and Sharing Center in Vista), make sure the computer being accessed has an account with the same name/password as the system connecting to it uses to login. NOTE: Vista's default is to require a password on the account to enable file/print sharing.

    While the default NetBIOS setting is correct for normal network configurations, it's possible for it to be altered, and it costs nothing to make sure it's correct. NETBIOS over TCP/IP must be enabled for normal network browsing. You can open a command prompt as described above and type the following command: nbtstat -n. This will display the status of NetBIOS or indicate it's not configured.

    Thank you very much for your detailed answer! I tried all the methods you mentioned, and I partially succeeded. Here are my results and issues:

    Out of 5 computers, 4 computers are able to "see" each other when I enter Workgroup, but I can access only 3 computers. It gives me this message when I try to access Tom's computer:
    Code:
    \\Tom[that's the name of my computer] 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. 
    I followed these microsoft's articles:
    http://support.microsoft.com/kb/913628/
    http://support.microsoft.com/kb/281248/
    And also made sure my quota is disabled on my drives, and regarding my firewall, it's disabled because Kaspersky Internet Security 2009 is "taking care" of it, but I don't think the problem is there, since all the other computers are running the same version of Kaspersky.

    I can ping from all computers to all other computers (without failures) EXCEPT the 5th computer (it is MSI WIND laptop), which can see only itself, and not even shown on the Workgroup in the other computers.

    I was able to share the printer between the 4 computers (one of them is connected via USB), but still can't share with the MSI WIND.

    What should I try now?
    Thank you again,
    Tom

    Well, the MSI Wind appears to still have a firewall blocking you, that's almost always the cause for what you see. I'm assuming that you can access the Internet on that one, but not any shared machines?

    Exactly, I can access the internet but not the network (can't see any computers at Workgroups except my own).

    And what about the other computer? (Tom's computer) How can it be accessed?

    I'd try this on Tom's computer.


    Create a file in notepad named FIXANON.REG with the following contents:

    You should have 3 boxes on the bottom in NOTEPAD.
    1)Filename : FIXANON.REG
    2)Save as type: all files
    3)Encoding: ANSI
    If you do not change it from txt type to All files type, then the file will actually be FIXANON.REG.txt, this won't accomplish the desired result.

    ------------------- Use text after this line -------------------
    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
    "restrictanonymous"=dword:00000000
    ------------------- Use text before this line -----------------

    Double click on the file and say Yes to the merge into registry question.

    Reboot the computer.

    Sorry, it didn't help. I'm attaching the file just to make sure I did everything right. I still can't access Tom's computer from other computers, even though it appears in the Workgroup.

    Let's see this from each of the computers.


    Hold the Windows key and press R, then type CMD to open a command prompt:

    In the command prompt window that opens, type type the following commands, one at a time, followed by the Enter key:

    Note that there is a space before the -n or the /ALL, but there is NOT a space after the - or / in the following commands.

    NBTSTAT -n

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    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.

    The details in the previous post belong to Tom's Computer (the one which can't be accessed by others).
    These details belong to the MSI WIND laptop (the computer which can't access the network and can't be accessed by others, but the internet connection is still working)

    Note the line:

    ..__MSBROWSE__.<01>

    in the NBTSTAT -n for the Tom's computer. Does this line appear if you run NBTSTAT -n on ALL the other computers?

    The reason I ask is, this line indicates that Tom's computer thinks it's the master browser, only one should appear in the network. If a normally working computer also has that line, then it's the real master browser, and this one is being blocked, most likely by some firewall component.

    The MSI Wind is the only computer which has this line (..__MSBROWSE__.<01>) and it's the only one that can access and be accessed by other computers.

    Tom's computer can see the other computers, but other computers can see him, but can't view it's files.

    I hope I was clear about it this time. What should I do next?

    Can you ping TOM's computer by computer name from the other computers?
