We have a wireless network at our organization that uses 802.1x authentication with PEAP. Users authenticate with their Windows Active Directory username and password. After connecting once to the wireless network, the client machine will automatically supply the username and password to the network the next time it sees the network.
We must change our passwords every 120 days. This requires the cached password to be changed on the wireless client machine. Otherwise the client will give the wrong (old) password to the wireless network. Currently the only way we know to to this is to delete the registry key holding this cached information. See http://support.microsoft.com/kb/823731
for the procedure.
Many users use their own personal laptops on this network. I am very concerned about having our users editing their registry files. Is there a GUI utility that will either delete this registry key or (preferably) allow the user to change the password that is cached for this specific wireless network (SSID)?
