Default Domain Policy

On a lab network I set up Windows 2000 Server and a client. I went to Active Directory Users and Groups. I right clicked the domain name then clicked properties to get to the default domain policy. I configured password policies on it. Then logged off. When I log back on, those policies I set are not enforced. It will not make me redo my password to comply with complexity for instance. What am I doing wrong? It is very frustrating.
