Sorry for not having answered before, I was away from internet.
The dummy.eps image you provided contains some text and a frame, at 
least that's the only thing I see in gsview and Corel Draw. It is 
vectorial. The dummy2.eps generated by gs 8.62 on Windows is also a 
vectorial image (much smaller, probably because the font is not embedded 
any more). So, the result is resolution-independent: Even if I zoom a 
lot, I do not see any resolution problem in the resulting dummy2.eps.
So can you describe what you mean by "bad quality"?

Here is the output I have from the command line when converting the 
dummy.eps using gs 8.62 on Windows XP:

GPL Ghostscript 8.62 (2008-02-29)
Copyright (C) 2008 Artifex Software, Inc.  All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
Loading NimbusMonL-Regu font from C:\Program 
Files\gs\fonts/n022003l.pfb... 2566848 1084635 13472696 12176047 2 done.

Wild guess: the difference could come from the font. Do you have the 
same message ?
There is one switch related to the fonts: -dNOPLATFONTS
Perhaps it could help...
gs 8.62 changelog specifically mentions some changes in font location. 
So perhaps you should try 8.62 on Windows(*).
http://ghostscript.com/doc/current/Fonts.htm also mentions the following 
(section6):
"If you don't seem to be getting nice characters on the screen under MS 
Windows, you can try adding aliases to Fontmap, according to the 
documentation you'll find in there."

Best regards,

Olivier
