After installing XP Mode on a Windows 7 Pro machine it keeps adding a bad route IPv4 Route Table===========================================================================Active Routes:Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 On-link 192.168.1.61 20 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.61 21If I disable Virtual PC and restrart the routing is right and everything works. IPv4 Route Table===========================================================================Active Routes:Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.61 20When I reable the Virtual PC it re-adds the bad route. I can do a "route delete 0.0.0.0" then a "route add 0.0.0.0 mask 0.0.0.0 192.168.1.1" or an "ipconfig /release" and a "ipconfig /renew" and everything works fine.But once I restart or disable and reable the XP Mode it starts happinging again. I have seen other post on the web having the same problem.http://serverfault.com/questions/109831/windows-7-virtual-pc-and-internet-gateway-problems-on-host-pcI have put in a temporary fix by using the gpedit.msc Under Local Computer Policy/Computer Configuration/Windows Settings/Scripts (Startup/Shutdown)/StartupTo add a file click Show Files and create the batch file in the provided windowI added a Startup.cmd script file that contains the following ----route delete 0.0.0.0 mask 0.0.0.0ipconfig /releaseipconfig /renew---This removes the bad route at startup.

Hi, I have also testes this on my Windows 7 test machine which has a Windows XP Mode installed; however, I could not find the route here. In settings of Windows XP Mode, I found there are 4 types of connection status, Not connected, Internal Network, Shared Networking (NAT) and your physical network interface. At this time, please also check these settings and see if it helps. Networking and Using Windows XP Mode Hope this helps. Thanks. Nicholas Li - MSFT

I have a Win 7 Ultimate PC that we had to reload today. After reloading Win 7 everything was fine and was able to go to the net and get MS Secrutiy Essentials. After Iinstall MS SE I let the machine run all pending updates. Then rebooted the machine. And since the reboot I am getting this same issue. Whenever the PC reboots it can get to everything on the LAN, but cannot get out to the net. I ranipconfig/all and everything looked OK except that default gateway showed 0.0.0.0 and 192.168.1.254. So I ran route print and I saw the same thing that you were getting. 0.0.0.0 0.0.0.0 On-Link . I can delete this route, renew the DHCP lease and the correct route appears (0.0.0.0 0.0.0.0 192.168.1.254). But rebooting the machine causes the route to revert back to 0.0.0.0 0.0.0.0 On-Link The machine does not have XP Compatabilty Mode or Virtual PC loaded on it. These are the only two things that I have been able to find on Google that cause this issue in WIndows 7. I have setup a batch file to run at startup as you described, and this works as a temporary fix. But I would like to find the cause and fix it. Have you found any thing else out about the issue?

No, I have not found the cause yet. I am still looking. I have 2 other machines that it started happening on both are running Windows 7 Ulitmate, one is a Dell with a Broadcom card and the other is an HP with a Intel nic. I have other machines running pro and home and I do not see this on them. Maybe Ultimate is the culprit? Moses Hull of Alexant Systems

I found a a post on Expert's Exchange that deals with this problem in Vista. I am going to look at the registry of my problem machine tomorrow for the empty values and maybe try the netsh winsock reset, if it works in Win 7.
