Lockout Resetter is a free utility that lets you reset and return to zero the lockout counter for users on a LAN, and the domains of the corresponding users.
Lockout Resetter is a tool designed for administrators or webmasters of LANs. The program also lets you list all the users of the LAN that are active at that moment, and decide for which of them you wish to reset the counter.
Logically, only those users with administrator rights can restart the lockout of other machines.
