    Hi Geogy,

    I did check both firewalls, and they are both disabled.

    Also, I did leave the windows open in the netsh test, and that did not seem to help. My issues with the link local clouds for groups still remain.

    My success with graphs at link local has been through my own modified application (one of the samples with the library I have written). It seems that I have no problem with graphs at either the global or link local scope, and groups at the global scope also work. It remains that only link local groups are the problem. I will continue some tests and try to get you any results that I have. If you have any other ideas, let me know.

    Thanks for your help.

         You did mention the firewall disabled. Is this the Internet Connection
         Firewall? Can you also check if the IPv6 firewall is disabled.
         
         Also in the register and resolve test, after you added 0.test1, was that
         netsh session still active or did that session just end right away. A
         PeerName registaration (by calling add) is only valid for as long as the
         netsh session is active. So you will have to resolve in the second window
         while the 1st session is still active. This can only be done by first
         getting into the netsh environment (c:\netsh) and then add a peer name ("p2p
         pnrp peer add 0.test1 <link local cloud name>").
         
         GraphChat and GroupChat by default register and resolve PeerNames in the
         Global Cloud. Have you made changes to these applications to run under the
         Link Local cloud?
         
         Thanks for your patience,
         Geogy
