Reset the time of each attempt
With this command you configure the time that elapses between the resetting of the attempts, that is the time to wait once the password limit has been exceeded. The command is net accountsw/lockoutwindow: XX, and in the X you have to put the minutes you want to spend as in the previous ones.
This is already the last command, so once you have configured everything to your liking, put Network Account and hit enter, this will confirm and change the parameters.
Disable blocking
If for some reason you get tired of having the PC with the trial block, you can always bring everything back to normal, you just have to go to the section where you did the above and write net accounts / blocking threshold, this will disable your previous settings.
