A couple of months ago our network setup changed here at the shop and I now have to check the "Use Default Gateway" on my VPN connection to get to any of our remote servers. This is really annoying as I can't get to anything on our other remote network which hosts stuff like source control while I'm connected adding to the overall time I spend on deploying stuff because I have to use my local machine as temporary waystation before getting to the actual live server.

I'm delighted to report that Steven Harman has what you need in his post VPN Connections and Default Gateways. The basic idea is to set up static routes to the remote network which negates the requirement of having to check the Use Default Gateway box. Great stuff.
