Things can get really strange. Recently we had a case when some Vista 
users were observing a similar thing - authentication went fine, DHCP 
was offering addresses, but these DHCP replies never reached clients. 
Other clients connected just fine. When we have rebooted the controller 
the problems went away. How was Vista special in this case, we never 
found out.
