Default Behavior

Performance Logs and Alerts is a Win32 service. In Windows XP it won't start until the current user starts it. When the Performance Logs and Alerts service is started, it is running as NT Authority\NetworkService in its own process of smlogsvc.exe. If the Performance Logs and Alerts fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the SysmonLog service has failed to start.
