First off, I am a newbie, so forgive me if this issue is already solved.But 
I could not find a valid resolution in my searches of this group.

When I run the example servlets from my NT workstation at home they 
complete without issue. When I run them from the Win98 machine at home or 
from my NT workstation machine at work they generate and display all the 
output, but the wait cursor continues for several minutes until it finally 
times out. To complicate the issue, if I specify the port (8080) in the url 
on my Win98 (or my daughters Win95) machine, it works correctly, but when I 
do the same thing at work, it behaves as described above. I have not 
modified the example code.

Here is the configuration:
Server -
NT 4.0 server w/sp6a - 266mhz, 64mb Ram, 18 GB hd, 2 network cards
IIS 3.0 (yes, 3.0 works fine other than this problem, and no, I don't want 
to upgrade to IIS 4.0, (it screws up the proxy server))
Tomcat 3.2 - default installation
cable modem
Winproxy (proxy/firewall software, for which I have opened ports 8080 and 
8007 for both incoming and outgoing TCP and UDP)
Internal network on non-routable address range 192.168.255.xxx, is not 
visible to the outside world.

Any assistance would be greatly appreciated. I'm stumped.
Thanks
