Dave, did you mean to type "WMS Server" in your subject?

Have you thought about setting up a cascading WMS server on Linux?
In your linux mapserver's map file, define a client connection to
your IIS WMS mapserver.  This may not be the highest performance
solution, but it'll get you online without advertising your
mapfile.
