Enable Analytic and Debug Logs
Applies To: Windows Server 2008, Windows Vista
Analytic and Debug logs are disabled by default. When enabled, they can quickly fill with a large number of entries. For this reason, you will probably want to turn them on for a specified period to gather some troubleshooting data and then turn them off again. You can perform this procedure by using either the Windows interface or a command line.
