Wireless Authentication

Hi there I wonder if any one can help me, I am the network administrator for
a medium business. We usually heve about seventy or so users on our domain,
but most of those users use notebooks and make use of the wireless access
points in the office.
It has however come under my attention that the users using wireless do not
get notified about their domain passwords that need to be changed. I supect
that it might be an authentication issue.
This is not a serious problem, but it gets quite annoying when I have
numerous end-users standing in front of my server room with stakes and pitch
forks because they cannot access any network resources. Is there perhaps
something I overlook in the AD that can be done to help notify the mob?
