[users@httpd] Installing Apache 1.3 on Windows 2003

[Techguy]

I just installed Apache 1.3.5 on Windows 2003, and when I tested it it
worked, but when I tried to install PHP I can't start the server anymore.
The apache server on the local machine started and then stopped...........
 
I used this website to configure PHP.

I have also changed the document root to another location, which did work
before PHP. So assuming I have followed the instruction on this site to the
T, what could be the problem????????
 
Thanks
