Password Synch for laptop users

[RedTech]

Here's the scenario.

Laptop is off and in the carrying case. User is at his desktop, password aging has forced him to change his password. User changes password then gets on a flight to Florida. User is now at hotel, pulls out his laptop, turns it on. User must login with his pre-aging password. User has successfully logged, then connects via ISP and VPN. When user attempts to utilize a newtowrk resource he is prompted for credintials, and must enter his new password.

Here's the question.

Is there a way to synch the password upon logging in to the network via VPN? Is there some kind of trick?

Thank you
