Finding the locked-out account

If password policies are defined, accounts with a large number of login failures will be locked out. Locked-out accounts in an AD environment can be found using the following command:

Search-ADAccount -Lockedout | Select name,samAccountName,Lockedout

If any of those in the list need to be unlocked, we can use the Unlock-ADAccount cmdlet to unlock an account.

For an individual account, perform the following command:

Unlock-ADAccount tuser4

For all the accounts on the list, perform the following command:

Search-ADAccount -Lockedout | Unlock-ADAccount

It is not a good practice to unlock all the accounts unless there is a specific reason.
