going into an elevated cmd prompt and issuing a route print would show all interface routes but no default. I ran into the second situation on a Wireless-G USB adapter, upon boot, would state unidentified network. It appears that Windows 7 'Network Location' keys off of said default route to identify which type (Work, Home, Public) is being used for a given nic, as it has to be able to tell with or without dhcp being enabled. The above comment is of the latter disposition. Suddenly all networks that had been "unidentified" were able to be remarked as "home" or "work", etc.Ĭan't take credit.found a post on another forum.but this needs to be spread far & wide.ģ.)One of two scenarios can happen related to Unidentified Networks it seems:ġ) your previously working network stops working because the default route is goneĢ) your previously working network stop works because the default route points to the wrong place The network stack used by XP, 2000, 2003 systems do not have this problem.Ģ.)go to a command prompt as admin and type: I don't know why Microsoft deciced to make the default routes 0.0.0.0 persist in the routing table instead of just being bound to the network adapter. If you have an isolated network (without any router, firewall, or gateway) with more than one computer - I do this in a development laboratory - is to choose for default address for Vista, 2008, Win-7, to be the IPv4 address of any other attached network interface. You must then reapply the necessary default routes to your interfaces (Do not use address of the network adapter as the default).
This removes the default routes from all network interfaces. My solution is to use the Windows Command Screen as Administrator and remove all default routes. This activates the "Unidentified Network" (Public) every time the network connection becomes active. Know here are some of the explanation for a solution that i found :ġ.) The issue is that the ROUTE table contains a phantom persistent default route 0.0.0.0 to one of the network interface cards.
