We have a windows 2008R2 environment with Windows 7 workstations.
Default domain policy is set to the following
Account lockout threshold - Not defined
It was defined when we first created the domain as 3 incorrect passwords and would lock, we since turned this option off but the accounts still lockout after 3 incorrect logins.
We then tried to extend the number of incorrect logins to 999 still the same!
We changed it weeks ago to Not defined and have performed gpupdates on servers and workstations but all still locks out on 3 incorrect passwords
We have checked all through GP and there is no other reference anywhere for password lockouts
Any help greatly appreciated
