Most DOS applications can be run within a Terminal Services
session, but you should avoid it if you can.
Here are some of the common problems:

* you cannot run a DOS application in full screen. If your
application demands this, you will have to install a custom screen
font which simulates full screen. Info + download here:

* DOS "graphics" are not supported

* many 16-bit applications monopolize the CPU by constantly
polling the keyboard. If your application does this, try a 3th
party utility called TameDOS:

* DOS apps tend to print directly to the LPT port. This can be
difficult to manage on a TS.

My advice: put your energy in upgrading the application to 32-bit.
If that's not possible, make sure that you *thoroughly* test the
application on a test server before you deploy it.
