Required INI settings
DNSServerIP=[put a real DNS server here]
The Windows server runs DNS Redirector and the Blocked page off-site from the end-user computers.  This may be beneficial for a variety of reasons; to manage the blocked.txt keywords list in one place that multiple sites will benefit from; to save costs by not having to place a server at each location; to prevent tampering by local staff.
In this example the external IP of the DNS Redirector blocked page is specified in the INI.  This is the correct configuration for most Firewall/Routers and when all the clients using the DNS Redirector IP as their DNS Server are located externally.
