"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Control keymgr.dll for saved credentials to resources.

Reboot the laptop, while connected to the LAN.
Likely issue, user hanged the password on the domain but the laptop cached credentials are from a time before the password change, the user brings/connects the laptop that is already logged in with the old credentials...access attempts to any resource leads to lockout.

Any germinal serves in the environment the user uses?  Check for disconnected sessions there.
