Do I need to change the localhost test if on a network?

Question

I have a JSP program running on tomcat webserver at home. This program works. At home the computer accesses the internet via a dialup modem.
I am trying to run this program at another location. I have taken my hard disk and installed the hard disk at the other computer. The other location is networked. It is running DHCP IP addressing. When I run the program there it does not work????
Also when I run the tomcat test there i.e
http://localhost:8080
In the status bar I get
Website found. Waiting for reply ...
but after few minutes I get the error message below:
why???
Please help
From home I ran the program as
http://localhost:8080/myJSPs/jsp/portal-project/preferences.jsp
this works perfectly.
At the other location I am trying the typing the same address in the address bar of IE6:
http://localhost:8080/myJSPs/jsp/portal-project/preferences.jsp
But it gives me the message in the status bar:
"Website found. Waiting for reply ... "
but after few minutes I get the error message below:

Answer 1

Tools->Internet Options->Connections->LAN Settings and tick the box "do not use proxy for local/intranet addresses" When I click on the "Lan Setting"
I get three check boxes that are located in two areas called Automatic configuration and Proxy Server:
Automatic configuration
[] Automatically select setting
[] use automatic configuration script
Proxy server
[] use a proxy server for your lan these setting will not apply to dial-up or VPN connection
At present none of these are selected.
So thus there is none to say "do not use proxy for local.intranet addresses" please help.
