I have the following scenario that I need assistance with - I want to run a 16bit dos app in xp that runs fine. But if I rdp into the vm it throws an error trying to open the 16bit app in full screen. How to display the dos app after the vm is headless.

Only idea I have is that 16-bit progs running full-screen are 640x480 resolution. Maybe setting the remote desktop window to 640x480 would allow the program to run?

Actually, "resolution" is a meaningless concept with most DOS apps, which ran in text mode only. If you prefer, then resolution was 80x25, probably with CGA color attributes in each character cell.
640x480 is a graphics mode display size, not really relevant at the DOS level (of course if that was the native display size of the chipset then it implied a certain font cell size in text mode).
