On Windows Vista, Windows 7 or Windows 2008 systems with Office 2007 or Office 2010 installed and Internet Explorer 7 or Internet Explorer 8, you attempt to open files from a SharePoint site using a Fully Qualified Domain Name (a URL including ‘.’ in the site name).
SharePoint 2007 or 2010 is hosted on Windows 2008 or 2008 R2 Server with WebDav enabled.
The SharePoint 2007 or 2010 site is setup to use Windows Authentication.
Users of the SharePoint site are expecting Client Integration (being able to edit and save directly back to the server) to be functional.
In this scenario, a user may see one or more of the following symptoms:
The user is prompted unexpectedly to enter their credentials.
The Office document will open in Read Only.
When opening SharePoint Explorer View an error will occur showing the path to the Document Library and a message of "Not Implemented".
When trying to save from Office back to a SharePoint site directly doing a Save As will not be an option. The SharePoint directory will not populate in the Save As dialog box.
When opening the document read only and then clicking on the Edit Document button, the user may see this error: "A problem occurred while connecting to the server. If the problem continues, contact your administrator."
This happens when Office detects that WebDAV is enabled on the server. If WebDAV is enabled then Microsoft Office also has to determine whether or not to open the document as ReadWrite or ReadOnly. SharePoint acts as its own WebDAV Server. Windows Server 2008's WebDAV Publishing role, if enabled, will interfere with SharePoint’s WebDAV functionality.
WebDAV Publishing should not reside on a SharePoint Server if the server is Windows Server 2008 or Windows Server 2008 R2. If the server is acting as a WebDAV Publishing server then SharePoint should be installed on its own server.
To remove WebDAV Publishing follow the below instructions:
Windows Server 2008:
Uninstall Microsoft WebDAV 7.5 For IIS 7.0 http://www.microsoft.com/downloads/details.aspx?familyid=8A47D609-8D95-4E1A-B2F2-2303E7E10EDC&displaylang=en component by going into Control Panel->Programs and Features and choosing Uninstall.
After removing the component then go into Server Manager Roles->Web Server IIS section->Remove Role Services->Uncheck WebDAV Publishing if it is checked. This will require a reboot of the Server.
Windows Server 2008 R2:
In Server Manager go to Roles->Web Server IIS section->Remove Role Services->Uncheck WebDAV Publishing if it is checked. This will require a reboot of the Server.
