There are default users created (Administrator and Guest are a few), which will all have a password associated with them. When any user attempts to authenticate or access any resource, the password for their user account is required. Now, thank goodness, a Windows Server 2003 (and later) domain requires a password by default.

There are many ways to protect a Windows password, this series of articles will discuss what you can do to increase security for your passwords.

When the user attempts to change the password for their account, this information is also sent to the domain controller. When the new password is entered by the user and sent to the domain controller, policies are in place to ensure the password meets minimum security requirements.
