Windows Vista vulnerability is having the problem of that a direct connection

Hello,
Windows Vista vulnerability is having the problem of that a direct connection is via a Patch Cable between two PCs or PC and Xbox, will detect as "Unidentified Network Binding", with applicable restrictions, (for example, the place are not of "public "at home" home “) with a router in between doesn’t exist this kind of problem.
Now I don’t have a router in the area and it’s also not needed for now. Few days back I found a work around for this problem exactly on the web, but no relief found for my issue.
So I turn to you.
Regards,
