If you just want other PCs inside your LAN to access the web site on your PC, you can amend the hosts files on each and every of the other PCs.
You'll find the file here: C:\WINDOWS\system32\drivers\etc
Make a backup copy of the file.
Note that it's called 'hosts'. That has _no_ suffix. Open with a text editor via a right click or from within the editor and then open file. Ok?
Add a line for your PC's ip [tab] webAddress. Eg:
For a PC with this line in it's hosts file, type www.yeeharrr.local
into the browser's address bar and it'll go to the web server hosted on your PC.
