    I hope you are still monitoring this, lakonst. I have been troubleshooting this for hours and yours is the BEST guide available on the internet! The problem I'm having after following your instructions for mapping from File Explorer to a "T" is that after each reboot Windows asks me for my credentials the first time I try to access the mapped drive in File Explorer. I have (always) checked the "Remember my credentials". When it asks, it auto-populates the password and all I have to do is hit "OK", so it's a minor nusance, but since I ahve this set up for my elderly parents, it confuses them sometimes. The credential is set up as a generic credential in Credential Manager. I hope you can help me. There's got to be a simple change somewhere that I am missing.

      The only I can think is that Windows Credential Manager has stored another password for the NAS. So, go to Control Panel > Credential Manager and delete all the credentials for the NAS. Then reboot the PC and try to connect to NAS again.

    Can anyone help shed some light on a couple issues im having. I followed the first set of steps exactly. I have yet to try the second method, but when I go to map the drive, it seems like it does exist, it asks to me accept the certificates, and then username and password, but then its says a device attached to the system is not functioning, and the drive mapping fails.

    Anyone have any ideas on that?

    This worked perfectly to share NAS a folder with my son in a different city. It shows up like any other network folder on the computer with the full read/write access I set up on the NAS.

    One question.
    When would you use
    or are they really the same thing?

      Yes, it's the same.

      No. And why to do that? since you can access it via its local IP?

    Saved my day! Thank you.
    I have tried to figure this out for over a day now. I always thought I had to identify the server with \\\share, not realizing that the key is to use https:// notation.

    Only sore is the speed, transferring locally, I manage 65MB/s transfer speed, going over the WebDav share, transfer drops to ca. 4MB/s. It appears that WebDav itself is the culprit. Any hints on increasing transfer speed? (internet connection is fiber at 1Gbit/s)

    The map directory does not work. I've already enabled Port forwarding on my router, external port and internal port are set to 5006, internal address is set to the Synology's. Yet mapping still fail. Error message: The mapped network drive could not be created because the following error has occurred: The network logon failed.

    I suspect the logon process requires more than just port 5006 ?

      These instructions are tested in real conditions and worked when written. Can you map the NAS public folder from the internal network?

        I think the issue here is that the instructions bypass generating a certificate for the NAS and installing it both there and the connecting computer. Without that, you'll get the errors that Joshua refers to (I just ran into the same problem).

          So how does that certificate work? It seems like you have to pay for one?

            Same question here. I having the same issue, both with Synology DDNS and No-IP, but I can easily map inside my network. I have 2 certificates on my NAS, how do I transfer them to the PC?

    Tried using WebDrive but there is no Secure WebDAV option. Their app UI is very different that what was is posted here. Is the product still a viable alternative?

    Had issues trying to map a network drive with the process. Have things changed since the article was written last year?

      WebDrive's latest version, WebDrive NextGen, was recently released (I work for the developer of the product) and it does look a bit different than previous versions. WebDrive does support WebDAV, but if you are having trouble, please feel free to visit our helpdesk and view our KnowledgeBase or submit a ticket via our online portal to our tech team and they will be able to assist:

    this only shares the root

    what if you wish to share certain folders to certain people?

      Setup Different Users with Different permissions on the NAS and use their credentials to connect with WebDrive.
