Open httpd.conf in a text editor. The httpd.conf file will be found in the AppServ/Apache2.2/conf directory.
Search for the word "DocumentRoot" in that file.
Place a hash mark (#) at the front of the line that starts DocumentRoot. This will comment out this line.
Write a new line that reads:
DocumentRoot "Full path to your Web site directory"
Then go down to a line that reads:
<Directory "C:/PROGRA~1/AppServ/www">
and change the path in quotes to your DocumentRoot path.
Restart Apache (go to your Start menu, All Programs, AppServ, and choose "Apache Restart" in control server by service).
If you want phpMyAdmin running on your server, you'll need to copy the phpMyAdmin folder from the AppServ/www folder into your new DocumentRoot folder. Login using the root username and password you defined in setup.
