THEMA: Web Folders (HTTPS WebDAV) unter Vista?

Unter Windows Vista "Windows Mail" Microsoft Communities MSNEWS Server

--- --- WebDav question von Jeremy Dennis

Zitat: I've tried connecting to our WebDAV server as I had in XP through adding a
network place, but after I enter the URL I get an error that states "the
folder you entered is invalid." If I map the drive either on the commandline
or through the GUI it works. Is this how WebDAV is connected now?
Thanks,
Jeremy Dennis

Hi Jeremy,
"Add a Network Place" should work for WebDAV resources as well. Are you
entering the resource using the http:// name or the UNC (prefixed with \\)
name?
Also, are you running a pre-RTM version of Vista? There was an issue with
"add a network place" wizard in RC2 that we fixed in RTM.

thanks

Hi Ather,

Thanks for your response but we continue to have WebDAV problems here at a
major university which uses https secured WebDAV in combination with an
eLearning tool We are using the RTM version of Vista with no success in
accessing the resource.

The WebDAV resource was able to be successfully added as a Web Folder
utilizing machines with Win XP and IE6 all recent patches. No changes to the
testing resource user name or password has occurred. All attempts to add
WebDAV functionality have failedwithin Vista. We have tried the following:

-Method 1: Accessing the WebDAV resource within IE. Result: Unsuccessful.
IE attempts to authenticate and then displays this error message: "Internet
Explorer could not open <https://...> as a web Folder. Would you like to see
its default view instead?". Clicking yes to this question renders a page
that only displays the root folder of the resource as an HTML document.

-Method 2: Add the WebDAV resource from within the "Add Network Location"
wizard. Result: Unsuccessful. No prompt to authenticate and response
displayed was the following error message: The folder you entered does not
appear to be valid. Please choose another"

-Method 3: Add the WebDAV resource using a Privileged Command Prompt and
the "net use" command. Result: Unsuccessful. Attempts to authenticate then
displays this error message: "System Error 5: Access is denied".
Infrequently will respond with the error message: "System Error 67 has
occured: The netowrk name cannot be found".

So far we have had no luck. Can you advise as to how we should proceed?

Thanks!
Mark

Hi Ather,

After writing my previous post I read additional posts and now understand
that the root of the problem seems to be the lack of the inclusion of the
WebFolders client within Vista.

The WebDAV redirector client would not be compatible with the design of the
site in question as particular users may not be able to be given access to
the root of the site. Since this is the case, is there a way to install the
WebFolders client in Vista?

Please feel free to clarify if you feel that this summation is inaccurate.

Thanks!
Mark

the problem in your case is that this site has a weak authentication
mechanism (Basic Auth) which is disabled by default on Windows Vista in order
to make Vista more secure. With Basic Auth, your username and password is
sent in clear text over the wire hence anyone sniffing the network traffic
can find out your password.

If possible, please have your website administrator change the
authentication type to something stronger (e.g. NTLM, Passport or Kerberos)
OR move to a SSL website (i.e. https://). Note that Basic Auth IS turned on
by default for SSL traffic.

If you really don't care about others finding your password AND you don't
have any sensitive data on this website, you can go ahead and enable Basic
Auth for non-ssl via the following registry key:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters "BasicAuthLevel" (REG_DWORD)

the default value of this key is 1. Changing it to 2 and rebooting the
system will make your scenario work.

Note that I HIGHLY discourage you to change this registry key due to
security reasons. Also, if you are not used to playing around with registry
keys, I wouldn't recommend doing this since if you happen to touch some wrong
registry key, you might make your system unstable.

Thanks
-Ather
