Remove Incoming Connections Non-Interactively

Im trying to figure out where the Incomming connections on Server 2K3 are
stored. I need to write a script to remove them from 2200 servers but im not
finding a registry key or a file that is associated with it. Stoping the
remoreconnections Service wont work for me as the machines must still be able
to initiate dial-up connections. I currently have a vbs to do this but it
must be run interactively which wont work for me in this case. Thoughts?
