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

Welcome to the Computer Science and Technology Study Materials section from CoreNetworkZ EdTech Solutions, a leading mock test and competitive exam preparation platform, for students preparing for SSC, DSSSB, and Kerala PSC examinations. Today, I will explain a connection error - Service cannot be started Error 1747.

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. Avinash Mathew, a B.Tech graduate preparing for the VSSC Technical Assistant post asked a tutorial in this topic.

This tutorial on CoreNetworkz Tech Solutions explains how to deal with the error Service cannot be started Error 1747: The Authentication Service is Unknown. Follow this guide, and you will solve it quickly.

SSC, DSSSB, and Kerala PSC conduct examinations for various IT posts.

Understanding network connection errors is essential for candidates appearing for the DSSSB PGT/TGT Computer Science, Kerala PSC Degree Level Exam, SSC Scientific Assistant (CS), VSSC Technical Assistant, and System Analyst posts. These networking fundamentals are core parts of the Computer Science syllabus.

Kerala PSC Degree Level examinations have a Computer Science section where students can expect questions that require them to explain the reasons behind network error codes. You can check the Kerala PSC Degree Level Common Prelims Syllabus under the Computer Science section. I recommend you download the syllabus using this official link.

1. Windows Socket Reset

   The first step to fix the error ( Error 1747: The Authentication Service is Unknown) is to reset the Windows Socket. CoreNetworkZ Tech Solutions published a detailed guide on resetting the Windows socket.

   Start the Command Prompt as administrator, type the following command, and press enter key.

   netsh winsock reset

   To go with advanced Windows Socket Permissions, follow this route.

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinSock2

   Right-click on the registry entry and click on permissions. Make sure that Winsock and Winsock2 have full permissions. Before testing with Registry, I recommend you to read the article provided below by visiting the link.

2. Services must be running with full permissions

   It is important to ensure the services are running on the PC with full permissions. To verify it, follow the registry path and make sure your current user has full permissions.
