Question : Why is Vista not shutting down?

I have upgraded three Dell Inspiron 1721 notebooks from the factory installed Vista Home Premium to Vista Ulimate edition.  These machines where then added to a sbs 2003 domain controller.  Now they will not shut off by themselves, have to hard shutdown everytime.   I left two of them on for at least 6 hours and they never shut down, just stayed at logging off.  

Answer : Why is Vista not shutting down?

Per the http://sbsurl.com/vista white paper:

"Power management is set to always on if the computer is plugged in (i.e. has a power supply) to ensure access via RWW"

The white paper has steps on how to modify these settings if you want to optimize on Vista's power management features.
