A local administrator can unlock a session that is opened by a domain administrator on a Windows XP-based computer

SYMPTOMS

When you log on to a computer by using a domain administrator account, and then you lock the computer, a local administrator for the computer may be able to unlock the session and access your session without using your domain administrator password.

CAUSE

This problem occurs when you enable Client Side Caching (CSC) on the computer. CSC synchronization adds a Setup option in the Unlock Computer dialog box. The Setup option permits local administrators to use their local administrator credentials to access the environment of the account that is currently logged-on without using the password for that account.
