This seems to work for 2003 TS and I have tested this on my Server 2008/2008 R2/SP1… Also, the download link for TS-DPI.zip does not seem to be working last time I checked (4/21/2012).
Cached download TS-DPI.zip here: http://cache.gmane.org//gmane/os/sol...ay/381-001.bin
After research, this seems to work well:
You may have noticed that users cannot access the Advanced button under Display Properties. This prevents users from setting the DPI.
Some users may want a larger overall font experience, unfortunately setting each of the fonts bigger under windows is kind of a pin. Additionally there is no nice way of making scroll bars, widgets, etc. bigger.
This is from my blog from back in 2012. I do not know if this will work for 2012/10. But it is worth a shot.
