Fix for Network Sharing Access

If you get error 0x80004005 when accessing a shared folder on your network, enable SMB 1.0/CIFS File Sharing Support in Windows Features (Control Panel > Programs > Turn Windows features on or off). Also check that Network Discovery is enabled and your firewall allows file sharing.
