Hello,

I have following issue: I have a WebDAV Windows Server 2012 with IIS and SSL signed by StartCom (so it is trusted by default). On Windows 8, I have no problem to map WebDAV over HTTP, however with HTTPS, I am unable to map it. I keep getting prompted for credentials all the time. I have tested this both on Windows 8 and Windows 8.1 RTM.

Now the issue is that when I tried it on Windows 7, it mapped on both HTTP and HTTPS. I really have no idea what I am doing wrong, but I believe this could be client related rather than related to Windows Server and the WebDAV setup.

Thank you.

Edit: When running  net use * https://files.domain.com in cmd under Windows 8, I get directly error 1790, on Windows 7, I am prompted for username and password.

Edit 2: When running net use * "\\files.domain.com@SSL\" /User:username password, on Windows 8, I get directly 1244 error.

Edit 3: As such as it seems, this issue seems to be related to: http://social.technet.microsoft.com/Forums/windows/en-US/1a3c29ab-d038-4132-af99-b85bce51b5c2/sslv2-being-used-with-webdav, since the symptoms seem to be the same, however there is no solution provided on that thread.

Edit 4: After running Microsoft Network Monitor, I can confidently say that the issue is indeed with the SSLv2 being used for WebDAV communications. See attached image.

Edit 5: I just used Network Monitor on Windows 7, where the drive maps correctly over SSL, see the difference in a picture below.

I would like to help, but I don't know any known issue related to this. I would just recommend you to check steps in some article like this one to verify you did not forget any step.

Thank you for your suggestion.

However that tutorial doesn't exactly apply on my situation, this issue seems to be Windows 8/8.1 related, since everything works correctly under Windows 7. I added screenshots from Microsoft Network Monitor, both Windows 8 and Windows 7 while mapping the same WebDAV drive. Windows 7 is successful, however Windows 8 seems to fail during the SSL handshake.

Jan,

I realize it has been a while, but how does the indicated solution relate to yours please?

The reason I ask is because your certificate is trusted while the solution's was self-issued with that being the problem.

Thanks!
