This policy setting determines how the SMB server selects a cipher suite when negotiating a new connection with an SMB client.

If you enable this policy setting, the SMB server will select the cipher suite it most prefers from the SMB client's cipher suites, ignoring the client's cipher suite preferences.

If you disable or do not configure this policy setting, the SMB server will select the cipher suite the SMB client most prefers from the server's cipher suites.

Note: When configuring this security setting, changes will not take effect until you restart Windows.
