server max protocol
The value of the parameter (a string) is the highest
protocol level that will be supported by the server.
Possible values are :
LANMAN1: First modern version of the protocol. Long filename support.
LANMAN2: Updates to Lanman1 protocol.
NT1: Current up to date version of the protocol. Used by Windows NT. Known as CIFS.
SMB2: Re-implementation of the SMB protocol. Used by Windows Vista and later versions of Windows. SMB2 has sub protocols available. SMB2_02: The earliest SMB2 version. SMB2_10: Windows 7 SMB2 version. SMB2_22: Early Windows 8 SMB2 version. SMB2_24: Windows 8 beta SMB2 version. By default SMB2 selects the SMB2_10 variant.
SMB3: The same as SMB2. Used by Windows 8. SMB3 has sub protocols available. SMB3_00: Windows 8 SMB3 version. (mostly the same as SMB2_24) SMB3_02: Windows 8.1 SMB3 version. SMB3_10: early Windows 10 technical preview SMB3 version. SMB3_11: Windows 10 technical preview SMB3 version (maybe final). By default SMB3 selects the SMB3_11 variant.
Normally this option should not be set as the automatic
negotiation phase in the SMB protocol takes care of choosing
the appropriate protocol.
Example: LANMAN1
Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
