Disable WPAD on Windows 10 RRS feed

  • Question

  • Does anyone know of good ways to test if disabling WPAD breaks anything?  We have Windows 10 Enterprise PCs, no proxy in the environment, and IE11.  Our users utilize a number of government websites, so I'm wondering if disabling WPAD would affect their ability to get to these websites while connected to our internal network.  

    I realize this is kind of vague, but was hoping somebody might have already been through this and had some suggestions.

    Thanks!

  • Hi Dans,

    Web Proxy Auto-Discovery Protocol, or WPAD, is a technology which aids a web browser in automatically detecting the location of a PAC file using DNS or DHCP.

    A browser that supports both DHCP and DNS will first attempt to locate a PAC file using DHCP, and should a DHCP configuration not exist fail-over to DNS WPAD will occur. If neither are configured, a browser will fail open.

    It depends on your configuration. If the websites your users need to access cannot be accessed without the proxy in WPAD, disabling WPAD would restrict their access ability.

    If the websites your users need to access could be access directly without proxy in WPAD, disabling WPAD won't affect their access ability.

  • You can check the current GOV sites and check them without WPAD

    Most sites should work without WPAD
