WinFax Pro and Digi Acceleport Ras

I can’t seem to get WinFax Pro to work with my Digi Acceleport Ras card. What do I need to do in order to get it to work?

I have attached a link that shows what Windows OS’s
are supported by WinFax Pro. The bottom line is that Windows 2000
Server, Advanced Server, NT 4.0 server or Terminal Server are not supported.
