We have just been megrated to Windows 2010 and Internet Explorer 2008. I'm always working in Sharepoint, but now when i'm trying to view documents through the "Explorer View" it gives me the following comments: Explorer View requires Internet Explorer 5.0 or greater and Web Folders. I think something is wrong with the working environment or the connection to the Web folders. Anybody sugestions. Thank you. Regards Thea

Hi Thea76, This issue occurs because of an incompatibility that is introduced by the improvements to Internet Explorer 8's URL handling logic, when it opens certain WebDav URLs. just so everyone is on the same page WebDav only works on port 80 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 didnt 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 Reference Sudeep Gopalakrishnan http://www.pubsub.com/Webdav-folders--no-full-functionality_Windows-MOSS-7tB9oLk7rqi,fVoMRAEGZf3E Sean McDonough SharePoint, WebDAV, and a Case of the 405 Status Codes http://sharepointinterface.com/2009/12/28/sharepoint-webdav-and-a-case-of-the-405-status-codes/ Todd Klindt, Installing Remote Blob Store (RBS) on SharePoint 2010 http://www.toddklindt.com/blog/Lists/Posts/Post.aspx?ID=174 Troubleshooting WebDav http://www.microsoft.com/downloads/details.aspx?FamilyId=C523AC7A-5724-48BE-B973-641E805588F4&displaylang=en KB Article for this with MOSS 2007 and explorer Reference http://support.microsoft.com/kb/2171959/en-us http://social.technet.microsoft.com/Forums/en-US/sharepointgeneral/thread/99d923cd-50e2-4a32-a45d-5df4f8627f37/ Thanks, Lhan Han
