In that case it's somewhat easier. Do you have admin rights on your PC? If so, try the following:

1. From a command prompt (start / run / cmd) with the VPN not connected, type "route print". The first line should say 0.0.0.0, subnet mask 0.0.0.0 and the gateway IP will be the IP address of your home router

2. Connect the VPN and repeat the process. You'll see another 0.0.0.0 / 0.0.0.0 line has been added, with a different gateway address. Remember this

Do you know what IP address range your company servers are on? Try typing ping [hostname] for a few of them and see if there is a pattern. Assuming they all start with 10.2.x.x (adapt as necessary), do the following:

At the same command prompt, type "route delete 0.0.0.0 mask 0.0.0.0 [gateway address from step 2]

Then type "route add 10.2.0.0 mask 255.255.0.0 [gateway address from step 2]

Now see how it works. A good way to check is to browse to www.whatismyip.com before and after so you can see where your connection is seen as "originating" from.
