Windows Explorer View issues with SharePoint 2007 RRS feed

  • Question

  • Config: Windows 7, 32 bit, IE 8 compatibility mode, SharePoint 2007 SSL site

    I am getting the classic error "Your client does not support opening this list with Windows Explorer"

    I have been through EVERYTHING trying to resolve this. Previous posts seem useful, but unfortunately do not work. I have tried adding into trusted sites vs. intranet sites, modified the registry for webclient parameters to add a multi-string value with the site's URL and have changed the DWORD value to 2 for BasicAuthLevel. It works on the XP machine we have in the office with no problems, but not this one. Have tried 32 vs 64 bit- IE and machines, and have tried previous versions of IE. It seems to me the problem is with the WebClient service (which is in fact up and running). We use smart cards to access the web site, when I select "Open with Explorer View" from the Actions drop down, I do get prompted to select a certificate from my smart card. I select it, it thinks for a little bit, and then the Windows Security pop up appears trying to use my local logon on credentials, which differ from the logon credentials I use for this particular SSL enabled site. How can I make this use my smart card credentials? I believe if it gives me that option I can have Windows Security "remember" it and I will be ok. Any help on this would be stellar!!

    Thank you.

  • Hi,

    In older versions of .NET WebDAV will have issues with SSL and FPRPC will have issues with Basic and Smart Cards. What's interesting is that you have it working on XP...

    Important points to be remembered when troubleshooting explorer view issues

    • The Ports 137,138,139 and 445 should be opened between the client and the SharePoint server. We can verify it using telnet<space><the SharePoint server name/IP><space> 137 and it should connect properly. the same can be done for ports 138,139 and 445
    • If we trying to access an intranet site using FQDN, its good that we add the site to the Trusted Sites zone on client computers as a dot (.) in the URL will make IE consider that its Internet and accepts the security configuration for internet zone.
    • Follow the KB article http://support.microsoft.com/kb/888123 if the error is similar
    • Apply if this is applicable http://support.microsoft.com/kb/892211
    • If you restart the web client service on the client operating system , its always better to restart the O/S as there are some known issues reported. (operating system prior to longhorn)
    • Apply this if suitable http://support.microsoft.com/kb/841215/
    • Avoid using Basic authentication . Basic authentication will work fine with WebDAV but has reported issues with FPRPC. If used , force web browser to use WebDAV
    • The account BUILTIN\NetworkService  must have read and write access to “Temporary Internet Files folder” to successfully complete a drag-and-drop operation.
    • Proxies configured in LAN also can cause issues in getting access to the explorer view http://support.microsoft.com/kb/832161/
