How can I browse my Tomcat localhost from another computer on the network?

Have you created an exception in your firewall?

Assuming that Tomcat is running on port 8080 and this is a Windows XP machine, the the firewall will block that port (not the case on Windows Server 2003).

The firewall can be configured by: choosing the Windows Firewall from the Control Panel, then click on Exceptions -> Add Port and enter name and number: Tomcat, 8080 and leave transport protocol as TCP

You need to use the Port of Tomcat which is by default 8080. So you might want to access you localhost on machine A from machine B as http://A:8080/YourProject And Remember Unlike IIS , it is case sensitive.
