I'm using DosBox to get a old piece of software working in a TS server. Dosbox has fixed all my problems with the old software, except one. If I use standard dos emulation built into Windows 2003 the software works in full screen but has a few other issues, but if I use DosBox I can get all the other issues resolved but I can't use full screen (it just messes up, make an unreadable mess) and screen scaling just doesn't want to work. Anyone have any ideas. I tried it in both a 2003 and 2000 server.

Have you tried adjusting the output= option in dosbox.conf?

In a TS session you'll probably only be able to use surface or overlay. By default DosBox uses surface which cannot scale. So try overlay.

Yup that looks to be the problem, TS only supports DirectDraw in blit mode not overlay, and WPF / Avalon which would work but DosBox doesn't support it 🙁

I'm guess I'm just screwed ..

One of the biggest problems with just using Standard Dos Emuation in windows is that the application using 100% of CPU because of keyboard polling anyone know of a way to fix that without dosbox?

I think if you were TS into Vista then supposedly Aero desktop would work....which means overlay/D3D would probably work and you could use DosBox there. Of course this probably won't apply until Server 2008 is out.

You could try TameDOS for NTVDM. Costs $$.

You could try this free INT28 idle implemention for NTVDM:
INT 28 idle implementation for NT VDM

Haven't tried it yet though.
