File/resource sharing problem over existing wireless network

    My existing wireless network was working fine until the laptop hard disk
    crashed last week and I'm in the process of rebuilding it. The nework was set
    up as follows:

    - Laptop running XP Pro, McAfee firewall (trusted IP addresses set).
    Connects directly to internet via broadband
    - Desktop running XP Home, McAfee firewall (trusted IP addresses set).
    Printers directly connected to this machine. Connects to internet through
    laptop via wireless network
    - Linksys Access Control Point

    Both machines can ping each other. Both machines have the same folders set
    for sharing.

    Laptop can access shared folders on desktop and print through the desktop.

    Desktop can 'see' laptop via 'view workgroup computers'. However, when try
    to connect to laptop from this screen, via start-run-"cmd" or drive mapping
    get error:

    "\\Clive-laptop is not accessible. You might not have permission to use this
    network resource. Contact the administrator of this server to find out if you
    haqve access permissions. Logon failure: the user has not been granted the
    requested logon type at this computer."

    Having read through postings to this forum, the Guest account has now been
    enabled on both computers (though it wasn't originally). This still hasn't
    worked. The restrictanonymous and restrictanonymoussam registry keys are
    unchanged at 1. The server service is running on both machines.

    The problem must be with the laptop as everything worked before the hard
    disk crash... Any suggestions?

    Many thanks.

    On the laptop, check to see if Simple File Sharing (Control Panel - Folder
    Options - View - Advanced settings) is enabled or disabled. With your LAN, you
    need to have SFS enabled.

    Did you enable Guest using Start - Run - "cmd", then type "net user guest
    /active:yes" in the command window?

    On the laptop, check your Local Security Policy (Control Panel - Administrative
    Tools) - User Rights Assignment, and look at "Deny access to this computer from
    the network". Make sure Guest is not in the list.

    On the laptop:

    1) Simple File Sharing was already enabled
    2) Guest was already enabled
    3) Guest was not on the "Deny access..." list

    So it was not these. By the way, when I type in "Net view clive-laptop" to
    the cmd window on the desktop, I get the error "System error 5 has occurred.
    Access is denied."

  4. On the laptop, click Start, click Run, type:
    Regedit (hit enter)

    Next, locate HKLM\System\CurrentControlSet\Control\Lsa

    Ensure that "RestrictAnonymous" is set to 0.

    Close and reboot.
    That should solve it.

    Thanks for the suggestion. I've set "RestrictAnonymous" to 0 on both
    machines and rebooted. I still have the problem.

  6. In the network properties of each machine, do you have Client for MS
    Networks and File and Printer Sharing installed (Also, on the xp pc, do they
    have checks next to them?)

    Thanks for the suggestion. I've looked at both machines and Client for MS
    Networks and File and Printer Sharing were installed and they had checks next
    to them. So, I still have the problem.

  8. Please send me the IPCONFIG info from each PC

    Click Start, click Run, type: cmd (and hit enter)

    Type: ipconfig /all >c:\ipconfig.txt (and hit enter)

    Use Notepad to open c:\ipconfig.txt and copy and paste entire contents into
    your next post.

  10. You're not running a router? You're using two NICs and ICS?
    Carey Holzman, Dec 13, 2004
  11. "The restrictanonymous and restrictanonymoussam registry keys are unchanged
    at 1."

    I just re-read this...

    You need to set RestrictAnonymous on both PCs to 0.

    Leave restrictanonymoussam alone, though.

    Carey Holzman, Dec 13, 2004
  12. Sorry, ignore that last message about restrictanonymous.. I read further
    down the thread and saw we went there already.

    I am curious how you have these machines configured. You have a wireless USB
    NIC on the desktop, and you have the cable modem plugged directly into the
    laptop and are using another NIC on the laptop to share that connection.

    Does the laptop have built-in wireless and you are in Ad-Hoc mode with the
    wireless NICs?

    That's just bad jo-jo with regards to wireless security.

    Although the Node Type shouldn't matter, I'd feel better seeing your Node
    Type set to Unknown. To do this, on each PC, run the registry editor, open
    this key:


    and delete these values if they're present:


    Reboot, then try IPCONFIG /ALL again to see if the Node Type has changed to
    UNKNOWN on both PCs. If so, try to access the network again.

    The original configuration was laptop with built-in wireless, desktop with
    Linksys wireless USB adapter and Linksys wireless broadband router (acting as
    an access control point only). The wireless network was set up with a unique
    SSID (not "Linksys"!) and WEP key, so my understanding was that security was
    okay. Initially, I ran this for file and printer sharing only until I was
    due to get broadband.

    However, when broadband arrived a couple of months ago, it came with a USB
    modem, so I couldn't plug the Linksys wireless broadband router into it. As
    a temporary measure, I connected the broadband modem to the laptop, so the
    Linksys router continued to act as an access point only. The bridge on the
    laptop was configured for wireless and local area connection so that I could
    connect directly to the Linksys box to configure/reconfigure when necessary.

    This set up worked until the laptop hard disk crashed.

    I've made the changes to both machines -- NodeType was not present on either
    but DhcpNodeType has been set to zero and the machines rebooted. Ipconfig
    now shows "Node Type: Unknown" on both machines.

    I still have the problem.



    PS In the spirit of trying to keep things simple, I had intended changing
    the USB broadband modem/Linksys router combination for an integrated wireless
    router/modem in the New Year (broadband modems with Ethernet ports seem
    almost as expensive and integrated units in the UK). I'd value your thoughts.

  14. If I understand correctly, the laptop has XP PRO and is inaccessible from
    the desktop which has XP HOME.

    Windows XP Pro: two policies can be found in Control Panel, Performance and
    Maintenance, Administrative Tools, Local Security Policy (or click Start,
    Run, and enter: gpedit.msc), expand Computer configuration, Windows
    settings, Security settings, Local policies, Assign user rights, then search
    for the two policies named:
    a.. Access this computer from the network
    b.. Deny access to this computer from the network
    Double-click on the second one. It usually contains a SUPPORT user. Some
    third party software adds Guest or some other user or group here.

    If Guest is included, guest access (all users who do not have an account
    with the same username and password on the target computer) from other
    computers is not possible and yields the above-mentioned error message.
    Remove Guest and all other groups or users who should be able to access this
    computer over the network. The SUPPORT user entry may remain in place.

    In the policy, "Access this computer from the network" make sure that the
    group Everyone is included. If not, add it as a new, last line under the
    other entries.

    (above copied from:

    Let me know if this helps.

    Some success!

    The "Deny access.." policy only had a SUPPORT user in it BUT the "Access
    this computer..." policy was blank. I added a group "Everyone" and can now
    see the laptop from the desktop. Thanks for getting me this far.

    However, the desktop cannot see the broadband connection. I've rerun the
    network wizard on the desktop just in case and reselected "This computer
    connects to the Internet through another computer". I've rebooted both
    machines. The laptop is connected to broadband but the desktop shows a
    standard Internet Connection icon which is "Disconnected". Previously, I
    could see the broadband icon on the desktop.

    FYI -- the broadband advanced properties on the laptop have been set for
    internet connection sharing (all three boxes checked). Nothing is checked in
    the "settings" option. I didn't set anything via this option before (so I
    can't say whether anything was checked previously or not).

    Not sure if this will help but I would delete the network bridge

    I would Disable DHCP in the router

    If you are going to us ICS then Windows ICS will give out the IP address

    If you are going to use a network bridge then you would have to but in the
    Default Gateway in witch I think? Is the Ip address of the USB modem and DNS
    Severs from USB modem you as well the Network card in the desktop would have
    to be set up manual with ip address as well Default Gateway and DNS Severs I
    am not sure if Default Gateway Ip address Is that USB modem or the ip off
    the network bridge

  17. What is the IP Address of the router?

    I cannot thank you enough for your help. I went looking on the site
    www/ that you referenced in your last reply and it
    pointed me to the "Truobleshooting ICS on Microsoft Windows XP" document from
    Microsoft. Then both you and Steve asked me questions about the router and

    Here's the final piece of the solution.....

    Set the IP address of the laptop to (the network wizard set it
    to this but I had changed it to to be in the same range as the
    Set the IP address of the router to (from
    Disable DHCP on the router.
    Reset allowable IP range on McAfee firewall on both PCs.

    Laptop now acts as ICS host computer. Desktop picks up IP address from
    laptop, and not the router.

    I now have no idea how my original set up ever worked. Perhaps I hadn't set
    the laptop as an ICS host, but the desktop still managed to find the internet
    connection somehow...

    Thanks again for your help. I am indebted to you (and my kids can now get
    back to instant messaging their friends!).

    All the best,
