This is NOT necessary for win 10 to work. I do not even know if it will work with win 10 but for sure it is not necessary. You are actually suggesting going backwards. >From the smb.conf man page: Default: server max protocol = SMB3 By default SMB3 selects the SMB3_11 variant. SMB3_11: Windows 10 technical preview SMB3 version (maybe final). I have a half dozen or so samba file servers that have a combination of win7 and win10 versions running and none of the config files contain anything that changes the SMB version. I would suspect if you have to mess with the SMB protocols to get win 10 to talk, you are doing something else wrong. Regards, -- Tom me at tdiehl.org
