Service cannot be started Error 1747: The Authentication Service is Unknown

Yesterday, I encountered a strange error with my Windows laptop while troubleshooting WiFi connectivity problems. I was at a public hotspot with a few friends. Except for this device, all other laptops could connect to the network.

It displayed the message - Windows cannot find wireless networks. While opening the Dell Wireless utility, it shows the status of the Dell adapter as disabled. However, Device Manager shows that the device is working properly.

A possible issue might be with the Wireless Zero Configuration service. For Vista and later versions, WLAN AutoConfig is doing the same function. We accessed the services page and found the specific service status as stopped.

We pressed the button start, but it failed with a strange error. You can read the error message the Windows showed below.

So, I decided to share this experience with my CoreNetworkZ readers. A large portion of our readers have Windows 11 and Windows 10 laptops. So, if they see the same issue, my experience with this error will help them.
