Security Event Log Failed Logons Reports

The Failed Logons Reports enable you to scan the consolidated log database for various failed logon Event IDs. This report is typically used by compliance and audit professionals while auditing domain controllers and stand-alone servers.

Server Manager includes two methods to report failed Windows logins:

One-Off Failed Logons Report Parses event IDs: 4625, 4768, 4771 and 4776, filters Logon Types, displays each failed login or the total number of failed login attempts grouped by user and Logon Type, then finally and optionally generates a summary table along with tables for each selected Event ID. This report is supported on all locales.
Generic Failed Logons Report Uses Regular Expressions to parse Security Event Log Entries, extract values, validate subject and target accounts in Active Directory, then finally filter entries using Event Log Filters. This report is only supported on English locales.
