Monitoring Microsoft Exchange Server

Before deploying Microsoft Exchange Server 2003 in a production environment, you should establish routine, automated monitoring and error detection strategies for your operating system and applications. Immediately detecting application and system errors increases your chances of resolving errors before the system shuts down. Monitoring can also help alert you of scalability needs. For example, if one or more servers are operating at capacity some or all of the time, you can decide if you need to add more servers or upgrade the hardware of existing servers.
For more information about monitoring, see "Monitoring and status tools" in Windows Server 2003 Help.
