/eventlog:filename

Specifies the name of a backup security event log to use as input to Auditlog.

Create a backup security log from the Event Log Viewer or with the

Auditlog/Clear:filename utility, which saves the current event log in filename

and clears the event log.

/clear[:backup_log_file_name]

Closes the current logon/logoff log file, optionally saves it as filename (for

back up purposes), and opens a new log file.

/? (help)

Displays the syntax for the utility and information about the utility’s options.

Remarks

Auditlog gives the administrator a powerful tool to verify and maintain system

security and correct usage. The information can be extracted as reports or as

comma-delimited files that can be used as input to other programs.

You must enable logon/logoff accounting in order to collect the information used

by Auditlog. To enable logon/logoff accounting:

1. Click Start, Programs, and then Administrative Tools to open Local

Security Policy.

2. On the Tree tab (left pane), select Local Policies and then Audit Policy.

3. Right click Audit Logon Events and Audit Account Logon Events, then

select Security.

4. Select Success and Failure under Local Policy. Click OK to save your

changes.
