Informix default servers on windows

I have two servers I need to connect to on a windows server. Instead of having an sqlhosts file it uses the registry and a setnet32 program to edit the registry. The setnet program has you set a default server as shown on this link near the bottom:

Whenever I do this is just overwrites any other server I have in there. Does anyone have any example of how their registry is set for this? I can't find the right configuration to make this work.

Any help is greatly appreciated!
