Domain member: Digitally encrypt or sign secure channel data (always) This policy setting determines whether all secure channel traffic that is initiated by the domain member must be signed or encrypted. If a system is set to always encrypt or sign secure channel data, it cannot establish a secure channel with a domain controller that is not capable of signing or encrypting all secure channel traffic, because all secure channel data must be signed and encrypted. Microsoft recommends to configure the Domain member: Digitally encrypt or sign secure channel data (always) setting to Enabled.
