Disable cached credentials via a domain Group Policy Object. The best way
to do this is by creating a container group for the laptop machine accounts
in the domain.

Caveats? The user will have to login via a RAS connection. The other
alternative is two-factor auth, which will allow safe use of cached creds.

"To turn off cached credentials, use a Group Policy Object (GPO) to set the
number of cached credentials to zero. Users can still log on using local
user accounts, but in most environments, it's unusual for users to have
local user accounts on their clients. You might consider changing the cached
credential setting only for desktop computers, as laptop users may have a
legitimate need to log on when they can't contact a DC."
