Once you find them, you can right click on the event and select Event Properties for more details. In the window that opens, you can find the IP address of the device from which the logon was attempted . STEP 2: Identifying Root cause : Identify the source of the failed login attempts using available information from the alert. Check the IP address associated with the failed attempts for any signs of suspicious activity or known malicious behavior. Determine if there are any patterns in the login attempts, such as sequential usernames or common passwords. Resolution for forgotten password: When user forgotten their password, follow these steps:- Login to the domain as an administrator.

Review and Continuous Improvement : Regularly review the effectiveness of the investigation process and make adjustments as necessary based on emerging threats and lessons learned. Continuously improve security measures to enhance the resilience of the system against unauthorized access attempts. VALIDATION: By the following sop the server administrator can be able to Investigate and repeated failed user login attempts.
