i have the same problem. i have 1 98SE and 1 XP pro running in a simple network with
a crosscable/switch (without internet yet, i want to get this running first)
if i connect one of the computer directly to the cablemodem on the LAN it works perfectly
but when i connect them to eachother they can see eachother and share files but takes
it hours to transfer a simple file from one station to the other.
also when i look at the networking tab in "windows task manager" the network utilization
doesn't get any higher than 2%.
i found some information about it on a site that has the same problem when using
their product and the're still "investgating" the problem.... (AAAAARHG! i need it
fixed now! :) )

>Situation:
You have a LAN with multiple Windows machines that are running various versions of
Windows prior to XP (an assortment of Windows 95/98/ME/NT/2000 configurations is
possible). A single PC running Windows XP has been introduced into your network.
The user of this machine has ACT! installed, and accesses a database stored in a
network location (not on the local machine). The network works fine on all machines,
until the Windows XP machine enters ACT! At that point, all machines on the network
except the Windows XP machine slow to a crawl, whether in ACT! or any other program.
The Windows XP machine still continues to function without problem.

>Solution:
Network Collision Resolution
This behavior is still under investigation. We believe it may be the result of an
optimization in the way Windows XP's TCP/IP backoff protocol deals with network collisions.
When a single Windows XP machine resides on a LAN, it may be forgoing the standard
backoff algorithm, thereby flooding the network and preventing the other machines
from retransmitting. This problem could be encountered with any high-bandwidth operation.
ACT! can generate a considerable amount of network traffic if you have several users
accessing a shared database. so therefore exposes the issue.

It specifically addresses 'High Rate of Collisions on 100-MB Networks: http://support.microsoft.com/default.aspx?scid=kb;en-us;q315237.
Refer to that document for registry modifications for customizing the adaptive backoff
algorithm.
