'' This script is designed to find inactive computer accounts in specified
AD domain.
'' Once it found inactive computer accounts, it will move it to a specified
OU.
'' The "Inactive" condition is based on "PwdLastChange" properity of
computer object.
'' A domain member computers will change it's password every 30 days by
default, except you disable this feature
'' on individual computer or through group policy. If you disabled this
feature on most computers in your domain,
'' don't use this scriptto clear inactive computer accounts in your AD
domain.
'' Any suggestion or feedback will be greatly appreciated.
'' If it found the time difference is less than specified value, it will
move it back to default computers container.
'' You muct create the ou before ypou run this script
