Solve 0x80004005 issue, cannot access sharefolder under windows2012

Maybe windows server 2012 enforced some security feature, but without any clue or tip for us to trace, when we suddenly find cannot access other machine's share folder, which causes a lot side effects like fail over clustering configuration or join domain.

1) We need to check whether "Client for Microsoft Networks" is installed or not.



if not, pls install.

2) Check one registry value, it is set as 0 or not.

Key: “HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters”

Value Name: RequireSecureNegotiate

Value Type: DWORD

Value Data: 0

If without this key value, you can directly create and set as 0.
