Yes, I think that kb article explains exactly what's going on your
situation. DAVE can see them all because it's using NetBIOS. Here's the
full article:
Macintosh clients stop responding with more than 50 volumes due to limitation
Cause:
The AppleShare 4.x server supports up to 50 volumes with 27 character names
or less. The Macintosh finder was designed to expect no more characters
than this. When the finder looks for a server share, it allocates memory
for a string that is 50x27 characters long. When the finder encounters a
server whose shares have a total string length greater than 50x27, the
server may stop responding.
Solution:
On a Windows NT server, you can successfully create and mount a few hundred
visible Macintosh volumes by giving the volumes very short names, such as
A1, A2, B1, B2, and so on. You can increase the number of volumes you can
create by minimizing the string length of the volume names.

I think that's your only option. If what you're trying to is have personal
folders, why not put them all in a few (or even just one) folder which is
shared and control access to them by file permissions rather than share
permissions. For the Macs they'll only have one volume to mount and inside
that volume all the folders will be locked except the one their login
permits them to use. The only drawback to the one-share method is Win95
clients can't map a drive directly to their folder (WinNT clients can using
the SUBST command), they would have to find their folder inside the shared
folder. The Macs can create an alias which will take them directly to their
folder and the Windows clients could create shortcuts to do the same
assuming the same individuals need to connect from the same computer every
time. If this is to allow 'roaming', I wonder if you could put a Mac alias
or PC shortcut on a floppy and have it work on another computer (of the
same platform type of course).
