You said that ADSM is their only TCP/IP application, that everything else
is AppleTalk.  You might want to double check that TCP/IP is running over
the Ethernet or TokenRing, and not AppleTalk(MacIP).  In general, AppleTalk
is a very slow protocol, and it possible this could be a problem.

Go to the TCPIP Control Panel.  At the top of the Control Panel, there
should be a pull down menu with the label "Connect via:".  This should say
either "Ethernet" or "Token Ring".  If it says "AppleTalk(MacIP)" then try
using straight Ethernet.

Just a thought...
