>I am trying to figure out how to get the IP address from the API under Terminal Services, and hoping that it shows the IP the client has connected to as the primary IP. I am hoping to be able to set up a loader that will load the proper program based on the IP that the terminal server session has connected to. Can this be done or do I have to setup a loader that asks them who they are?

Cy,
If your intention is to distinguish them then what about getting their NIC address using UuidCreateSequential (w2K, XP) or UuidCreate ( Version < 5.x) ?
