What is the web page address and which end of the problem are you dealing with?  Are you the viewer trying to see a web page or the author trying to get the web page to work?

What kind of web page is it and what kind of web server do you have?  Plain HTML, ASP, PHP?  HTML pages should simply work if you have the correct address and access.  ASP and PHP need to have the handlers installed properly.  Are you seeing any error messages?  Can you browse to it on the machine that hosts it?

As you can tell from my questions, the first thing is to establish what does and doesn't work and under what conditions.

There so many possible reasons that you could write a book on it.  Here's a short list.

1. See if the server and network are up and running.
2. If they are, make sure the files are where they are supposed to be.
3. If possible, browse to them on the machine and see if they work locally.
4. If it's a script page, make sure the script interpreter is installed and has permissions to run.
5. If it's database driven, make sure the database is running and accessible.
6. Check the web address and IP to see if they are both correct and resolving correctly thru DNS or the local network.
7. Find out where the users are trying to access it from and make sure they are actually able to connect from there.
