I have a local network that connects ten computers. But ever since I have established the network, my account keeps getting locked out. The standards are set to lock the account after five bad passwords What can I do to find the problem and then fix it?
1) Download a tool that shows account lockout status.

2) Run the Executable file.
3) Enter the “Username” and “Domain name” and other administrative details.
4) Check the results that will display the bad passwords used and the user that used those passwords.
5) Check the Security Log of the domain controllers that show the locked account. There will be an Event ID set to “4771” that contains the target username. Look for the failure code that shows “0x18” as its value.
6) Make a note of the Client’s IP Address. The IP belongs to the computer that has encountered the bad password.
After that you can either lock the client completely or take other suitable actions.
