WinHTTP Proxy Service Stopping on Server 2019

DylanDD13 

Hello DylanDD13,

WinHTTP Web Proxy Auto-Discovery is a Win32 service. It provides support for auto-discovering a proxy configuration by implementing the Web Proxy Auto-Discovery (WPAD) protocol.

If the WinHTTP Proxy Service Stops and throws an error, "The endpoint mapper database entry could not be created." then you can follow the steps below to troubleshoot the issue.

Boot the system in safe mode with networking:

Booting your computer in Safe Mode with Networking forces your computer to load with only the essential drivers and services.

• Firstly, press the Windows key on the keyboard and click Power.
• Next, while holding the SHIFT key on the keyboard, click Restart.
• Now, Windows will reboot and prompt with a few different options.
• Then, select Troubleshoot and choose Advanced Options.
• Now, select Startup Settings and click Restart.
• After rebooting, Windows will prompt with several other startup options.
• Lastly, press the number 5 key on your keyboard to enter Safe Mode with Networking.

Thus, you can launch programs, browsers and download files from the desktop to fix any issues you might have. You can simply restart the system from safe mode to return to normal mode.

Perform a clean boot in the Windows server:

A "clean boot" starts Windows with only essential drivers and programs to diagnose problems.

• Firstly, select Search, type msconfig, and then select System Configuration.
• Next, on the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all. Select Apply.
• Now, In the Startup tab of System Configuration, select Open Task Manager.
• Then, on the Startup tab in Task Manager, for each Enabled startup item, select the item and then select Disable.
• Nextly, close the Task Manager.
• Lastly, select Ok to restart the server on the Startup tab of System Configuration.

Note: After restarting the server, you'll have a clean boot environment. You must restore the system with changes made after completing your troubleshooting.

Check and Repair System Files:

You will have to scan all protected system files to review for any corrupted files on your system.

• Firstly, click on Start, type cmd, and a command prompt will appear
• Now, right-click on Command Prompt to open with Admin rights.
• Then, type the below command and hit Enter to proceed:

SFC /scannow

Note: You will have to wait until the process complete

If you get an error message containing corrupted files, then remove the corrupted files.

• Lastly, restart the Windows server.

I hope the above ways help you to troubleshoot the issue and that WinHTTP Proxy Service starts without facing any errors.
