Having successfully had IP Routing enabled on the various Beta and RC builds of Windows 7 I have now done a clean install of RTM and cannot get it to work.I have two network cards in my system routing between two subnets, 192.168.1.0 and 192.168.3.0. Static routes are set up in a router on each subnet and I could certainly see the "other" subnet right until I did a clean install. I have set the usual registry key to 1 (HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnableRouter etc) but whatever I do a IPCONFIG /ALL shows "IP Routing Enabled. . . . . . . . : No" and neither subnet is visible from the other.Any idea what I am missing?Steve

Problem solved, found that the "Routing and Remote Access" service was set to disabled. Changed to Automatic and started and all now working! Have Microsoft changed the default action of this service recently??Steve

Hi Steve, In Windows 7 this service is disabled by default.Arthur Xie - MSFT
