Denying access to C: drive with Apache Server

httpd.conf

# The httpd.conf is designed for user configurations. 
# You really should not edit the apache2.conf as it may be updated by future upgrades.
# An additional option is to just put your custom configuration into /etc/apache2/conf.d, 
# all files in this directory are included as well.

# This entry denies access to C: drive
