How do I unlock the Parallels Plesk “admin” account after too many failed login attempts?

In Windows:

1. Log in as administrator via Remote Desktop Protocol (RDP).
2. Click Start -> Run. Type “C:\Program Files\SWsoft\Plesk\MySQL\bin\mysql.exe -u admin -p -P8306 -D psa -e DELETE FROM lockout” (without the quotes) into the text field in the Run box.
3. Enter the admin password when prompted.

In Linux:

1. Log in as root via ssh.
2. #mysql -uadmin -p -P8306 -D psa -e ‘delete from psa.lockout where 1=1’
3. Enter admin password when prompted.
