Windows 8 and DFS troubleshooting

I had a problem on a W8 workstation and a dfs share, the user has also activated the offline file function.
The user still get on file list and dir only the directory available offline.
 
After some test I have found this solution:

1. Add this registry key
HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
New DWORD
Name RequireSecureNegotiate
Value 0
As per http://support.microsoft.com/kb/2686098

2.
Disable offline files
add this registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Csc\Parameters
Name FormatDatabase 
New REG_DWORD 
Value 1

Rboot
Enable Oflline file
