PHP Works on Server but not from another browser

[anegin]

When I run my PHP application directly from the server using http://localhost:81/ it works.  When I try to access the server from another browser by running http://ifw-2k8fs4:81/ it doesn't work.  Any ideas what the problem might be?

I have PHP on ifw-2k8fs4 and MySQL on ifw-2k8fs3.  I'm running IIS 7 on ifw-2k8fs4.  I do not have an apache server running.  I figured that was my problem.  I installed apache on the ifw-2k8fs4 server using port 81 and tried to run the application.  Instead of the application running I got back a message saying It works!

I uninstalled apache, and now I'm back to my original problem.  Any ideas?

PHP doesn't run on its own. Either way your still going to need a web-server such as Apache.
