Error 403 When attempting Multiple Sites on Local Computer - Running WAMP

"You don't have permission to access / on this server"

I've searched numerous forums looking to find the answer to this problem. I have tried several and to no avail. Any help anyone can provide would be greatly appericated. I created and installed a basic Drupal site. I copied the "Drupal" database into a new database and named it "sandbox". I granted all permissions to user "adminsanbox" @localhost. I set the settings.php in the /wamp/www/drupal/sites/sandbox equal to the database settings $db_url = 'mysql://adminsandbox:pwd@localhost/adminsandbox';
I uncommented 'Include conf/extra/httpd-vhosts.conf' in the wamp\bin\apache\apache2.2.8\conf\httpd.conf .

The '\conf\extra\vhost' contains

NameVirtualHost *:80

ServerName sandbox
DocumentRoot /www/drupal/sites/

I also tried adding this block of code to vhost

NameVirtualHost *:80

ServerName sandbox
DocumentRoot /www/drupal/sites/
directory /wamp/www/drupal
AllowOverride All
[/directory]

**when I added the "directory" block, wamp would not come online - I received an error msg. Only when I returned the vhost to it's original state was I able to get wamp back online (thank goodness for "copy"-the orignal file before making any changes)

I've tried changing the name of the .htaccess file in "/wamp/www/drupal" to see if I would be able to access the site without .htaccess - received same message "You don't have permission to access/on this server".

Here's the error message from the log: [Sat Jul 05 21:54:43 2008] [error] [client 127.0.0.1] client denied by server configuration: C:/www

I know this error message has to do with permissions & Apache but I've finally hit the wall after 5 days. Please help :-)
