I have two Win2k machines, one Win98 machine, and two Macs networked. 
One of the Win2k machines was extremely slow in transferring files to 
the Macs. I decided to use Ethereal to try to figure out what was going 
on. I installed it on the "slow" Win2k machine and captured some 
information. When I tried to install Ethereal on the "fast" Win2k 
machine, it required me to upgrade Internet Explorer from v5 to v6. 
After doing that, the previously fast machine also transferred files 
slowly to the Macs.

The two Win2k machines also transfer files slowly to each other (a 22Mb 
file takes 6 minutes), but quickly to the Win98 machine (a 22Mb file 
takes 30 seconds). The Macs and Win98 machine all transfer files 
quickly between each other.

So now this seems to be an IE6/Win2k-related problem and not a 
Mac-related problem. Any insights will be greatly appreciated.

Thanks,
