11.13 Network monitoring

---

Exchange is layered on the corporate network. For example, the Active Directory Global Catalog servers are especially important for Exchange, and a Global Catalog that is experiencing problems can adversely affect Exchange. Responsibility for monitoring the underlying network generally falls to a network operations group rather than to the Exchange administrators. Rather than duplicate the work of the network operations group, the Exchange administrators should rely on existing network monitoring facilities.

However, the Exchange administrators should ensure that the network operations group would notify them if a network problem occurs that will affect the Exchange messaging environment. An Urgent alert should be generated if the network problem also will cause the messaging backbone to be down.
