Resolution: Remove WEBDAV Publishing component from IIS 7.0 Windows 2008 R2.

The WEBDAV component has also been known to cause the following issues

· Office Clients not uploading/saving to SharePoint Sites.

· Explorer View not working on Document Libraries and Lists (Saw this while troubleshooting during live meeting)

· Using UNC paths to access SharePoint lists or libraries does not work.

· Syncing with OneNote to SharePoint Libraries does not work.

· Office Documents opening in Read only mode.

· The following KB articles covers a few of the above listed issues

The reason is that SharePoint has it’s own WebDAV and the IIS7 WebDAV publishing interferes with it. Unless the WebDAV publishing Role has been added to the Server for a specific reason, SharePoint should not need it. Note that removing WebDAV does require the server to be rebooted afterwards.  If you do a network trace between the client and the SharePoint server you will most likely see 405 events coming back when Office fails to save the documents to the SharePoint site.

Fight Comparison:
Definitely a team effort, I was scratching my head on this one. I’d have to say Leonard vs. Hearns I. Once Leonard figured out the Hitman’s game, he took him out in the 14th.
