Open with Explorer: Network Error – Windows cannot access [email protected]

Problem: 
Open with Explorer button in SharePoint 2010 site gave this error message on a particular document library.

Network Error - Windows cannot access URL@SSL\DavWWWRoot\SiteURL\Library  You do not have permission to access \\web-app-url@com@SSL\DavWWWRoot\Library-URL. Contact your network administrator to request access.

Network Error – Windows cannot access [email protected]\DavWWWRoot\SiteURL\Library
You do not have permission to access \\[email protected]@SSL\DavWWWRoot\Library-URL. Contact your network administrator to request access.

Observation: 

  • The issue is happening only with a particular library. Explorer view works fine with all other document libraries in the same environment. The issue is not specific to a particular client machine or user.
  • Open with an explorer from the Root level of the library and got the above error. Tried going into each sub-folders and clicking on “Open with Explorer” worked fine, Except for one folder where SharePoint prompted for credentials three times and gave “Your client does not support opening this list with Windows Explorer.” – So that’s the culprit.

Solution:

Tried running Windows update, Various hotfixes from Microsoft KB’s. But finally, renamed the problematic folder by manually typing the same name, and it worked!
