We are working on SharePoint 2013 On perm. When I am trying to open a SharePoint Document Library in 'Explorer View' (Open with Explorer button), I am getting a message. This behavior is the same for all the users.
\sitename\DavWWWRoot\LibraryName is not accessible. You might not have permissions to use this network resource. Contact the administrator of this server to find out if you have access permissions.
A device attached to the system is not functioning.
I am the site collection administrator. The Library has 57000 items in it.
