If a machine logs on a Windows NT domain, a password is created for identification in the domain. This password and this type of communicatrion are called a secure channel. The password is changed every 7 days in Windows NT and every 30 days in Windows 2K. If you forget your password, the PDC will disable the secure channel after the machine has missed the password change twice.

If a trust relation is etablished between several Windows NT domains, a trust password is set with the trust domains which will store that password in their SAM. A difference between the trust passwords and the secure channel passwords may appear. Users will not be able to log on trust domains. On member servers the logon service is disabled and it is only possible to log on a local account. It is impossible to use remote resources.

If those problems occur too often, you may want to make passwords static with
