Isn't there a proper "place" in the GUI to enable routing

That would be in Routing and Remote Access Services (RRAS). But unfortunately that service doesn't exist in W2KP - only server. Enabling it in the registry is a hack, but as far as I can tell, it's the only way to do it.

<stab>Andy - Did you enable any new services before it started flaking out on you? Or install any new software? Software firewall perhaps? </stab>
