Windows Server 2016 and SharePoint sites “Open with Explorer” mode


We’re having a problem opening this location in File Explorer. Add this website to your Trusted Sites list and try again.


In case you are using Windows Server 2016 and you want to connect to your SharePoint sites using the Explorer mode, there are big chances to encounter “We’re having a problem opening this location in File Explorer.” warning message.
That’s because the WebClient windows service (responsible for the “translation” into Explorer mode) is by default not installed with the Windows Server 2016 OS. The same story was also on Windows Server 2012 and Windows Server 2012 R2 (and the fix was to activate the “Desktop Experience” feature from the Server Manager console).


This time (in case of Windows Server 2016), in order to get the WebClient windows service you need to activate the “WebDAV Redirector” feature.









And in order to work properly, you need to make sure the WebClient windows service and Trusted Sites are properly configured:
1. Adjust the WebClient windows service settings via Windows Registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters).



Restart the WebClient Windows Service.



2. Make sure you add your SharePoint sites part of the Internet Explorer Trusted sites list.



For the Trusted Sites Zone configure the Automatic logon.




Once these are done, the Open with Explorer mode will work.
