There has been a surge in the number of account lockout incidents in the past several years. The increase is in large part due to the number of BYOD devices that are connecting to today’s networks. These devices often cache passwords making it easier for users to connect to backend email or networks resources.
These cached passwords can cause the user’s account to become locked out if the user’s Active Directory password is changed, but the cached password is not updated. When the user’s account is inaccessible due to lockout the user is not productive and the help desk is going to get an expensive call.
One of Netwrix’s most popular freeware is Netwrix Account Lockout Examiner. Account Lockout Examiner help desk staff identify lockout root causes in a single keystroke. Using this tool you can see what makes the same account lock out repeatedly without having to dig into cryptic event logs.
Microsoft does provide a utility that may help in some limited situations, but Account Lockout Examiner picks-up where Microsoft’s tool stops.
If you want more information on how to find account lockout source you can visit the Account Lockout Examiner freeware page.
