What kind of server? If it's a Windows server, check out this terrific site
for cross-platform networks.

http://www.macwindows.com/

For your problem, check out the link in the list on the right regarding
cross-platform issues for Mac OS 9. It's labelled "Mac OS 9 X-platform
issues." There are numerous issues with networking in Mac OS 9.2,
unfortunately....

What evidence do you have that it's a duplex mismatch problem? What stats
can you get from the switch? And can you change the setting on the switch? I
guess it's a good guess considering that it works with a hub and not a
switch, but there are other possible explanations too...

There's the infamous problem of the switch nor forwarding traffic quick
enough (due to STP) upon startup, so the Mac misses the DHCP response and
perhaps AppleTalk replies too. But that would cause an immediate problem,
not a slowdown...

One thing you can do to fix networking problems on a Macintosh is delete the
Apple Share Prep, AppleTalk, File sharing, and TCP/IP files from the
Preferences folder. Reboot and let the Mac start over with fresh files. You
would need to reconfigure TCP/IP after doing this.

Sometimes it helps to zap parameter RAM (PRAM) also. PRAM stores various
preferences. You can use a tool called TechToolLite to do this.

Wish I could be more help. We haven't run into an duplex mismatch problems
on our network of Macs with OS 9.2 and switches.

Perhaps a search in Google would help?
