Running Hog4 PC as backup to RH4 through Parallels Desktop

I am trying to run a Hog4 PC + Superwidget as a backup to my RH4, through Parallels Desktop on a MacBook Pro. I have successfully set up the network, which I have previously proven by running Light Converse with the same system setup. However Hog4 PC cannot see the show file to log onto. I am confident the network is set up correctly, does anyone now of any particular settings to tweek on the Parallels interface. I suppose Bootcamp is the obvious next step.
