You can use this procedure to enable or disable the global query block list on the Domain Name System (DNS) server. For more information about the global query block list

You need to complete this step if you wish to use WPAD in your organisation:

If you wish to enable it again type this:

dnscmd myserver /config /enableglobalqueryblocklist 1

Replace myserver with the name of your server :)
