Splitting VPN Internet Traffic

I had an instance where someone was using the default windows VPN client on a Windows XP machine connecting to a SBS 2003 server. They were complaining that when the VPN was connected, web browsing traffic was being routed down the VPN and not taking advantage of the fats 8MB line they had.
They asked if there was any way of splitting the traffic so that the Internet would use the local router and all other traffic go down the VPN. Well, transpires there is.

1.       Make sure the VPN is disconnected first
2.       Right mouse click on the connection and select Properties
3.       Select the Networking tab
4.       Then click on TCP Internet Protocol
5.       Click on Advanced
6.       Then uncheck the Use default gateway on remote network
7.       Click OK three times
8.       Now only traffic destined to remote network will go through VPN

This works with XP, Vista and 7 VPN connections.
