Microsoft Event Viewer

Microsoft Event Viewer is a Microsoft Windows system tool. It is available by default on every Windows NT-based system (Windows NT, Windows 2000, Windows XP, and Windows Server 2003). Beginning with the introduction of Windows 2000, Microsoft Event Viewer has been managed through the Microsoft Management Console (MMC). It is possible to create an MMC that includes the Event Viewer of each remote system. But keep in mind that using more than one Event Viewer on one system often leads to confusion and is normally not recommended.

Windows stores information related to an event or error in Event Viewer. Event Viewer can be used to gather, identify, and analyze Windows 2000 system events and information about hardware, software, and system problems. Because Cisco CallManager runs as a Windows service, information about Cisco CallManager events and errors can also be stored in Event Viewer.

Event Viewer, available at Start > Settings > Control Panel > Administrative Tools > Event Viewer, can help identify problems at the system level. For example, to pinpoint a problem, use Event Viewer to look for events involving Cisco CallManager Administration on the Internet Information Server (IIS) server.

As shown in Figure 31-3, Event Viewer uses log types to group different kinds of logs:
