Windows 10: How to know WPAD is enabled on dhcp client?

Hi, I'm trying to send proxy configuration through DHCP option 252, also known as WPAD. After setting, the proxy works, and the traffic is led to the proxy, but I can't find a way to tell that WPAD is enabled on DHCP clients. I have tried many places to seek the detected URL or maybe the IP of the proxy, but nothing returns, as shown below.1. Winhttp: netsh winhttp show proxy -- no return value2. proxy configuration in explorer -- no valueeg: chrome://net-internals/#proxy3. Settings/Networks and Internet/proxy -- no4. key value in registry -- empty or even no keyHKEY_CURRENT_USER\Software\Micr

DHCP option 252 wpad issue

This is more of a bug report now I've located a fix, would be nice if someone could weigh in on whether this will be patched or not.

Deploying option 252 in a dhcp scope deploys proxy.pac location to the client registry:

HKEY_USERS\S-1-5-19\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Wpad

when moving to a new scope without option 252 this location is not forgotten and proxy continues to prompt for authentication until registry key is manually deleted.

Is this by design or a bug?

 

Communicating with the DNS server

Since you got the error "unable to contact your DHCP server", this could be due to a disabled DHCP client. We suggest following these steps to enable it:

• Click Start.
• Type services.msc and press
  Enter.
• Find DHCP Client from the list of services and check the status.
• If DHCP Client isn't running, right-click it and choose
  Start.
• The DHCP Client Startup type should be
  Automatic. If it's not, double-click it, choose Automatic.
• Click Apply.
• Click OK.

Check if you can use the ipconfig /renew command after enabling the DHCP Client. If you're still unable to connect to the Internet after this, we recommend uninstalling your network
adapter driver by following these steps:

• Right-click the Start button and choose Device manager.
• Click the arrow beside Network adapters and double-click your network adapter.
• Go to the Driver tab.
• Click Uninstall device.
• Restart your computer. This will prompt Windows to automatically reinstall the correct driver.

Let us know what happens after enabling the DHCP Client and reinstalling the network adapter driver.
