Arrggghhh... There are so many possible solutions to your problem (as you haven't explained it properly) By the way, why are you trying to make the forums run in W:\www\ and not in a folder of W:\www\? I'll list 3 solutions that I can think of here: 1) Put them in a folder of W:\www\. For example, you will have your 1st forum in W:\www\Forum1\ and your 2nd forum in W:\www\Forum2\. With this, you'll have to use http://localhost/Forum1/ and http://localhost/Forum2/ (to view your forum) instead of http://localhost/ that you have been using. 2) A Multi Forum phpBB Installation. The only disadvantage of this is that you'll need money and a Linux/Unix based server. 3) Virtual Hosts running on different Subdomains, Hosts or Ports with a different DocumentRoot. I think solution #1 would be the best
