When you want to deploy an autodiscover proxy configuration for your clients, you can use WPAD with DNS.
However Windows Server DNS can reply non-existent domain for an wpad domain name request.
This behavior is by default and can be decomposed in two parts:
- If WPAD configuration is already in place when you install the DNS server, no action is required.
- When you want to set up a new WPAD configuration after DNS installation, you need to edit the block list on all your DNS servers.
