Windows Explorer / SharePoint 2007

It is a known issue that with Internet Explorer 7 or 8 and Windows Vista or Windows 7 that the Windows Explorer view within SharePoint will not work. I spent hours scouring the nets and found this solution below. Worked like a charm. Btw, I am running Microsoft Office SharePoint Server 2007 on a Windows 2008 R2 Machine.

On the Client

Ensure your WebApplication is in the Local Intranet security Zone



When you use Internet Explorer to access the WebDAV site, Internet Explorer uses Windows HTTP Services (WinHTTP). WinHTTP sends user credentials only in response to requests that occur on a local intranet site during an authenticated logon process. However, WinHTTP does not check the security zone settings in Internet Explorer to determine whether a Web site is a local intranet site. Instead, WinHTTP depends on the proxy settings in Internet Explorer to determine whether a Web site is a local intranet site. If the Automatically detect settings option is not enabled, any auto-configuration script that is defined will not be processed. WinHTTP will not identify the WebDAV site as a local intranet site. Therefore, WinHTTP will send out a request without user credentials, and you will be prompted to type user credentials.



On the WFEs

Check if the WebServer > Role Service > WebDav Publishing is installed on the SharePoint WFEs . I have had this issue and the only way I found the resolution was with Fiddler, another farm to compare where I didn’t have the issue, and Google.



Disabling the component is not enough, it must be removed completely from IIS using the following steps:



1. Open Server Manager

2. On the left side of the pane click on Roles

3. Scroll down to the "Role Services" section, and click on "Remove Role Services"

4. Under "web server" uncheck the box next to "WebDav Publishing"

5. Choose Next, then choose Remove

6. A reboot will be required
