Also might be worth mentioning that the "Computer Browser" service doesn't appear in my system services.

I'm on Windows 11.

Now... If you want to connect the WebDAV to your computer on reboot, there is one key thing you need to do, as it is not set correctly by default. Open your System Services (services.msc) and look for "Computer Browser". Change the startup setting on this service to "Automatic", then start the service. This will save you a lot of headaches when you reboot your PC.

The other thing you may need to do when you setup the WebDAV as a mapped network drive is to create a batch file that runs on startup (as your regular user account) that will disconnect then reconnect the mapped network drive, since for some reason, Windows chokes on reconnecting WebDAV endpoints as a mapped network drive. You can do this either by putting a string in the Windows Registry (HKLM\Software\Microsoft\Windows\Current Version\Run) or by adding the batch file into the startup folder within the start menu.

The commands for the batch file should be as follows (assuming that the drive letter you are using for the drive is Z

net use Z: /delete
net use Z: \<IP or Hostname>@SSL<path to folder> <password> /user:<username>

So in this example, we're going to use example.com as the hostname, and remote.php\folder as the folder, Monkey69! as the password and username as the username... So the second line would be

net use Z: \example.com@SSL\remote.php\folder Monkey69! /user:username

Hope this helps
