This policy setting determines whether a domain member should attempt to negotiate encryption for all secure channel traffic that it initiates. If you enable this policy setting, the domain member will request encryption of all secure channel traffic. If you disable this policy setting, the domain member will be prevented from negotiating secure channel encryption. Microsoft recommends to configure the Domain member: Digitally encrypt secure channel data (when possible) setting to Enabled. Countermeasure: * Enable the Domain member: Digitally encrypt or sign secure channel data (always) setting. * Enable the Domain member: Digitally encrypt secure channel data (when possible) setting. * Enable the Domain member: Digitally sign secure channel data (when possible) setting. Potential Impact: Digital encryption and signing of the "secure channel" is a good idea where it is supported. The secure channel protects domain credentials as they are sent to the domain controller. However, only Windows NT 4.0 Service Pack 6a (SP6a) and subsequent versions of the Windows operating system support digital encryption and signing of the secure channel. Windows 98 Second Edition clients do not support it unless they have the Dsclient installed. Therefore, you cannot enable the Domain member: Digitally encrypt or sign secure channel data (always) setting on domain controllers that support Windows 98 clients as members of the domain. Potential impacts can include the following:
