The secure channel is used to validate the member servers or workstations membership in the domain, based upon its hashed password. This discrete communication channel helps provide a more secure communication path between the domain controller and the member servers or workstations.  It can also be used to change the accounts password, and to retrieve domain-specific information, handling NTLM authentication pass-through to the domain controller, or from DC to DC for the same.    When you join a computer to a domain, a computer account is created, and a password is shared between the computer and the domain. By default, this password is changed every 30 days. The secure channel’s password is…
