Network security: Minimum session security for NTLM SSP based (including secure RPC) clients  This security setting allows a client to require the negotiation of 128-bit encryption and/or NTLMv2 session security. These values are dependent on the LAN Manager Authentication Level security setting value. The options are:  Require NTLMv2 session security: The connection will fail if NTLMv2 protocol is not negotiated. Require 128-bit encryption: The connection will fail if strong encryption (128-bit) is not negotiated.  Default: No requirements.
