Using an account lockout policy means trading one risk for another. You are
reducing the risk of a brute-force password attack, but establishing a system
where an attacker can lock everyone in your domain out of their computers
in a matter of minutes (in a Denial of Service attack). Even if that doesn't
happen, it generally tends to increase cost-of-ownership (help desk calls,
resets, etc.) and reduce productivity (during the time the user cannot access
his or her computer).

You may wish to consider addressing the root risk: requiring strong passwords,
and/or moving to two-factor authentication.
