BB,

The lack of responses to your previous messages indicates that there is
noone else (reading this list) that has this problem or is interested in
debugging it.  This usually means that you'll have to debug this yourself
(sponsoring a developer who would debug it for you has also been
suggested; I'm sure if you offer, interested parties will show up). ;-)

As a suggestion, you could start with comparing the outputs of "strace
agetty" on all the relevant machines to see if you notice any glaring
differences.  There might also be a difference in the versions of Windows
DLLs (IIRC, some of the networking DLLs don't come standard with Win95, so
you have whatever was packaged with programs/service packs), so you might
explore downloading the correct versions from Microsoft.  Those are just
WAGs, BTW, but they should be enough to at least get you started.

If all else fails, there's always the source...
HTH,
	Igor
