Mounting WebDAV drive in Windows Server 2012

Just solved this on a 2012 R2 for connecting a WebDAV drive from OwnCloud 7 server via HTTPS (think it's same on 2012)

1. Install Desktop Experience

server manager > Add Features > User Interfaces and Infrastructure > Desktop Experience

2. Start and set to Automatic WebClient Service

services > WebClient > Properties > Set from Manual to Automatic then start it

3. Enable BasicAuthLevel in regedit

open regedit.exe and go to this key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

set the DWORD value "BasicAuthLevel" to "1"

4. reboot
5. connect to your WebDAV

net use z: "https://.." /user:username password

Here is the solution to this problem for Windows Server 2016:

1. Install WebDAV-Redirector component via PowerShell

   Install-WindowsFeature WebDAV-Redirector –Restart
   

2. Verify that WebDAV-Redirector is installed properly

   Get-WindowsFeature WebDAV-Redirector | Format-Table –Autosize
   

3. WebClient service should appear in your system. By default it is started in Manual mode, just set it to Automatic and that's it.

4. Reboot
