To cut a long story short I had to configure a VPN server and a machine that was also running active directory. After I had got everything set up as I thought it should be I was still getting an error message when anyone tried to connect. The error message was:

Error 733, A connection to the remote computer could not be created.  You might need to adjust the protocols on your computer.

Which was accompanied on the server by a message about no protcols could be agreed upon or somethng like that. I spent days trying to figure this one out without much luck. The problem is that the messasges don't actually tell you what has gone wrong. In my case it was that the clients that were connecting to the system weren't being given an IP address as the VPN server didn't have DHCP installed and there were no DHCP relay agents configured. I tried to configure my router as a DHCP relay agent but it was having none of it. The solution was to open the vpn server properties and in the IP tab set a reserved range of addresses. Simple when you know how.
