Windows 7 PCs can't see each other on the network

Posted on 2011-04-25

Can't get the Homegroup to work anymore. It was working just fine. I don't know what happened or what I did. So I try to select 'Networking' on the tree to see the other PC and it wants a network logon & password. I don't recall ever setting up such a thing. This is all wireless.

Asking the mods to please place this in a 'networking' tag of some sort as I cannot seem to find one.

    Open Control Panel -> Network and Sharing center -> Change Advanced Sharing settings.

    Make sure on all machines:

    1. The network connection has not been set to public.
    2. In the Home/Work setting that  Homegroup is selected (down at the bottom).

    Check all machines.  ... Thinkpads_User

    Without more details its a bit difficult to speculate on what might be wrong.

    How many machines are in your Homegroup? Can *none* of them talk to each other now?
    Do you know the IP addresses of the machines? If you do, can you open up a Command Prompt and perform a "ping" to each one of them and get a response?
    If your entire setup is wireless, are you sure your router is still doling out IP addresses properly for your network?
    Is there any chance that a firewall has been turned on or reconfigured on any of the two machines

    That's just a very basic first set of things to check, but hopefully it can serve as a starting point. When network connectivity starts going haywire suddenly like this, I start to suspect things like routers and switches first...then work from there.

    Good luck.

    Perhaps after checking these settings, if you changed any, you should restart the computers. ... Thinkpads_User
