In a Microsoft Windows domain, starting with Windows , a discrete communication channel helps provide a more secure communication path between the domain controller and the member servers or workstations.

This channel is known as a secure channel. 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 stored together with the computer account on the primary domain controller PDC. The password is replicated to all replica domain controllers. When a computer updates its computer account password with a domain controller, the event is logged in the system log of the authenticating domain controller.

In this scenario, the computer's secure channel with the authenticating domain controller is still valid.

Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk. Windows Server General.

In your original post you state " When I want to join a Windows 7 Professional Clean install to the domain I receive the error message on the Windows 7 ", which seems to imply that you are unable to join the Windows 7 client to the domain.

Yet in a later post you state "Yes. I can join the domain and do a nslookup ", which seems to imply that you are able to join the domain. Which is it? Are the machines joined to the domain? If so, when are you getting the error?
