Passwords CAN and DO expire if that option is chosen by the administrator.
In fact, it is the default option...one has to choose an option "passwords
never expire" in order to prevent it.
From the Windows XP Help and Support Center:
Resetting passwords
In Windows XP, passwords have an expiration date. If you are scheduling
recurring tasks that you want to run indefinitely, you need to be aware of
the expiration date on your passwords. When your computer password expires
you will need to reset the password for your scheduled tasks.
Note
a.. To change or set a new password, open the task. On the Task tab, click
Set Password.
Educate yourself before you go giving bad information on the internet.
