Windows 10: How do you Disable WPAD from doing DNS queries?

i face the same problem like this one How do you Disable WPAD from doing DNS queries? - Microsoft Community has anyone been able to solve this?

Stop WPAD in Windows 11.

Hello,

I am asking for help on how to stop my laptop from sending wpad dns requests. I have a pihole on my network, and the log is littered with wpad requests.

I tried the first couple of techniques in this tutorial but no luck. How to disable Web Proxy Auto-Discovery (WPAD) in Windows 11/10 (thewindowsclub.com)

I disabled netbios and lmhosts in the network adapter. Edited the hosts file per the instructions. Still my dns logs filled with wpad requests. I couldn't figure out how to edit the registry and don't want to totally mess up my laptop.

Stopping the requests is beyond my technical ability. Can someone provide simple guidance or point me to a simple tutorial on how to do this? Thanks.

 

wpad issues

I have an odd issue that i am unable to track down sort out. Have put this under windows instead of IE11 because it seams to stem from windows internet options.

In our business we have a very long proxy.pac file because there are internal domains that are only reachable via specific proxies they are not publicly resolvable. One of these sites is old and runs on aspx so requires IE (we are migrating it along eventually)

Across multiple devices Edge(chromium) or chrome the wpad lookup works correctly and the site opens, unfortunately it doesn't function correctly (aspx)

However on some devices when opening in IE11 it works fine.

On another subset we get DNS not found, as thou it is totally skipping the wpad process.

Another interesting side effect on these hosts that don't work if we try to open URLs in edge that are not FQDN ie http://internalsite (which is also http://internalsite.internaldomain)

We get

No authority could be contacted for authentication

unless we go to local intranet zone and check Automatically detect intranet network (on the other set of devices that IE11 works fine this doesn't need to be checked)

We are awkwardly in a split domain network (in transition) so these sites would normally use NT login (sharepoint) however these devices are no longer part of that domain so we have to authenticate domain1\username when the login pops up.

We have tried disabling AutoproxyResult cache (How to disable automatic proxy caching in Internet Explorer - Microsoft Support)

wpad override (K12USA Support Knowledge Base)

The wpad key is empty otherwise not showing a cached entry that i can see.

Now if i manually set the proxy statically ie http://wpad/wpad.dat it works fine, but this obviously breaks the host when we move backwards and forward between on VPN and off VPN.

Have checked the dev console (F12) however this doesn't show the pre GET/CONNECT process.

I'm also in a situation that currently devices are at home, so wireshark to check what dns lookups occur for wpad are encrypted out the interface so no idea if the lookup fails, but given nslookup from cmdline wpad resolves, wpad.internaldomain resolves
and http://wpad/wpad.dat works i'm a bit lsot.

It's like something has told it to skip the wpad process in IE11 but works fine in edge, or something wrong with resolution of internaldomain stuff.

This is on different identical hardware and fresh installs, we have only been on this platform for a few weeks overall so devices are very fresh.

 

Stop WPAD in Windows 11.

Hello David McC86，

Welcome to Microsoft Community.

In fact, preventing WPAD from sending requests can be solved by changing the registry. I recommend that you change the network adapter Settings back to the default Settings and then follow these steps to modify the registry to prevent WPAD:

1. Please click the search type Regedit on the taskbar and open the registry editor.
   
2. In the address bar go to
   
   
3. In the window on the right of Wpad, right-click and create a dword32 key named WpadOverride and value is 1.
   
4. Then click OK to save and exit, restart the computer and see if there are no more WPAD requests in the network log.
   

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Your patience and cooperation are highly appreciated. Please feel free to let me know if you have any doubts or updates.
