    I have a wireless network which links to my PC to my laptop when I bring the latter home to the Netgear Router attached to my home PC and share printers and also access the internet via a cable modem attached to the router.

    My set up is working OK but in the Event Log of System I frequently get a red cross and the following error message

    Event 4321

    The name "WORKGROUP :1d" could not be registered on the Interface with IP address The machine with the IP address did not allow the name to be claimed by this machine.

    I assume that this a conflict between the PC and the laptop, as the router is Is there anything I can do to stop this error occurring? [I have looked at the advice in MS help but the answers in short is don't bother, it is to complicated.]

    Here's the question - Does your laptop have to have a static IP address
    like that? Is this a work laptop and is the static IP necessary?
    Because what is happening is that both computers are on different
    subnets. If you don't have to have a static IP, then just set it to
    automatic and you won't have any problems connecting to any other

    Sounds like a good answer but I need some more guidance. In the Netgear
    MR8402 settings the pages for the IP address are dynamically assigned but
    the mac addresses are the same.

    What more should I do?

    The mac addresses don't change - they go with the hardware. I don't
    quite know what you mean by "pages for the IP address". What you should
    be looking at is on the laptop, not the router. On the laptop, go to
    your Local Area Network connection, right-click it and take Properties.
    Then look at the Properties for TCP/IP. You'll have a choice of whether
    to assign IP addresses automatically or statically. Unless you have to
    have a static IP address on the laptop for work, choose the automatic

    Thank you for your help.

    By pages I meant the net pages that I see when I access the router on to configure it.

    I have looked at my Laptop Properties for TCP/IP and set it to automatic. I
    will see if this fixed the problem at start of this thread.

    May be there is another cause:. Normally I use a fast 4Mbps cable connection
    and I know that occasionally the ISP drops the connection, because while I
    am running an application which is using the Internet occasionally I get a
    popup which shows that it has switched to my backup connection, which is a
    cheap 512K ADSL because it has a low free use threshold. The wireless
    network cannot access this connection which is USB directly into my
    If your fix does not cure my problem, do you think this could this be a
    cause of the error messages?

    Certainly. You shouldn't be losing your cable connection like that. Talk
    to your cable provider. You might need a new cable modem or there could
    be a problem with the line.

    I think that your solution has fixed the problem any way today. However,I
    will take this up with my ISP []. I know they have been
    making some big tech changes to increase speed last weekend which could be
    part of the problem.

    Many thanks again.

    Are you by any chance a Sci-Fi fan? There was a brilliant Xworld Ambassador
    called Malke in Frank Herbert's "God Emperor of Dune" saga which I still
    read again from time to time.

    I'm glad things are working. The problem could just have been the
    automatic IP address. It never hurts to check with the ISP, though.
    There have been times when I've spent an hour troubleshooting my
    network just to discover there was an outage in the area. Doh!

    Yes, I love Sci-Fi, although Malke is my real name. It means "Queen" in
    Hebrew. Which is as it should be. ;-)

    When I set up the router I used the addresses as below (I have x'd the MAC
    addresses for security)
    Attached Devices

    # IP Address Device Name MAC Address
    1 LAPTOP x

    I am still left with a small irritant. From time to time I get the error
    message given below in Event Viewer\System. Is it because I put the IP
    addresses in the wrong order or is just something that does not matter?

    The browser service has failed to retrieve the backup list too many times on
    transport \Device\NetBT_Tcpip_{604888D3-8C69-4A9E-9349-1187B9614E17}. The
    backup browser is stopping.

    I'm not sure it should matter, but I think I'd put the desktop on instead. It sounds like your laptop is trying to find the
    browse master, possibly from your work environment. Leave the Computer
    Browser service running on the desktop and try disabling it on the
    laptop. If someone else has a better idea, I'm sure they'll be along in
    a moment!
