    Computer Keeps on Dropping off Home Network


    Hello,

    I am trying to network 3 computers. A Win7, Vista and a Mac. Fun stuff.

    I know this is Win7 forum, but I thought I'd ask. The Vista machine keeps on dropping off the network. I am able to access it for a few hours at a time, but then it drops off randomly. Here are some observations:

    -When I try to access a mapped drive it says: "The Local Device Name is Already in Use"
    -When I look at the network map from the Win7 machine, it says that the "discovered device (Vista machine) cannot be placed on the map"
    -When I look at the network from the Win7 machine, the Vista machine is listed, but says the path is not found.
    -I have no problem connecting to the internet from the Vista machine.
    -I cannot view the network map from the Vista machine-- it says "cannot start mapping on the adapter"

    I am trying to figure out how to ping the thing. But I am not sure how to do that.... other than that, Im stumped! Any help would be greatly appreciated!!

    Hello justiciero,

    Try out this tutorial: Internet Troubleshooting Guide - created by Dinesh

    You might try repairing the computer with: http://www.vistax64.com/tutorials/66...c-command.html and http://www.vistax64.com/tutorials/88...all-vista.html, both if they work, or just the first one if the latter doesn't.

    If you can post screen shots of the ipconfig/all from the Vista machine and the network map from the Windows 7 machine it would be very helpful.

    Yep ok you have the 6 to 4 tunnel adaptor problem, nothing new really but it usually indicates that you should update your network driver.

    In order to get this working again those extra 6 to4 adaptors need to be removed.

    Click on the file below and save, right click and unzip then run the file and reboot the system. This file is made to remove all the extra 6 to4 tunnel adaptors so you don't need to do it manually.

    After running the tunnel remover and rebooting, run the next file below that one which will reset your IP and everything else. Your system will reboot itself automatically.

    After that your system may connect to the internet again but you should look for an updated version of the network driver for your Vista machine. :)

    It might also help to remove the DNS entries from your IPv4 properties windows and add the DNS server addresses to your router's set up page for the DNS settings instead, you can get to your routers set up page by typing 192.168.0.1 into your browsers URL.

    This will make your default gateway show up where it says DNS servers which means you are getting the DNS through the router instead.

    thank you very much! i implemented these solutions and so far so good. the computer hasn't dropped off the network as of yet. i am going to continue to monitor it over the next couple days, and hopefully this will be the solution!

    Yes give a few days to make sure.

    The tunnel adaptor problem is common, using a different network driver can help fix the problem for good if you can find one.

    As I mentioned earlier, replacing the network driver with a more updated version should keep this problem from reoccurring again.

    hi chev65. thanks again for your help. it seems that this was indeed the problem. I have had no problems with maintaining a connection to the network.... until last night! last night the computer dropped off the network again, and I looked to see if the 6-to-4 adapter was there, and sure enough it had reappeared. I actually tried to install a new network driver but the automatic driver update did not find a more updated version. So i think this network driver is probably the root of this problem in the end.

    So I consider the problem solved, pending a new network driver! I can't keep deleting this 6-to-4 adapter every couple days!

    It's ok to have the 6 to 4 adaptor there, it's part of the network. The problems start when you get too many of them which seems to be caused from the network driver doing strange stuff.

    You should try going to the manufacture's web site for the driver, you haven't listed any system specs so I can't find one for you. :)
