help with one pc on two networks

[Dirk]

I connect to my home network via vpn from school. the connection works fine but i am having issues with duplicate ip addresses. I try to access a network drive on a computor on my home network but... there is a computor on the school network with the same ip address. when it does a dns lookup for the name of my home pc it comes up with the correct address but then proceeds to connect me to the pc on the school network with that same ip. is there anyway to specify which network i am trying to reach? i have never dealt with a single pc being on multiple networks before and dont want to have to change my home network settings.
