Places to look:
Radius logs if Radius used
IIS if it proxies authentications
Logs on the AD server that the lockout occurred on
VPN logs
On all devices clear any saved passwords:
Clear WiFi, E-mail and VPN saved passwords.
Do they use RDP?
Are there any other applications that authenticate that can save passwords?
i.e.: Lync / IM

Logs or events show attempts from the exchange server.
What tool can I use to determine exactly what is causing the bad attempts that
