I have setup WEBDAV on a Windiows 2016 server. I can connect fine to it using the URL in a browser, but cannot map a drive to it or even add a network location.
I have tried using several different 3rd party webdav clients and none of them work.
I spent over 2 hours with Microsoft support last night and they could not figure it out either.
I have tried 2 different Windows 10 machines as well with the same results.
