[KLUG Members] another box to linux?

[bill]

I have an opportunity to recommend that a client change their Windows 
box to a Linux box.  Lots of good reasons (mostly the incessant 
Microsoft vulnerabilities), of course, but one gotcha.

They have an old DOS-based (!) app that they have to be able to run on 
this machine.  They actually run it as a shortcut over the network. 
That is, they have a link on their desktop that refers to this program 
on another Win machine.  The program will not run correctly on Windows 
if I copy the program to this box because the data is still on the other 
machine, where it has to stay.  So, this box just maps the network drive 
and uses a shortcut to the program on it.

Long story short, is there any chance I could make this box Linux and 
still make that program run?  I have a Linux box on the network already 
I can use for testing.  Any advice, recommendations?

kind regards,

bill
