You are a messaging professional. You manage a Microsoft Exchange Server

2007 messaging system with four computers that run Exchange Server 2007 in each site. You have 11

Microsoft Active Directory sites.

One or more of the Hub Transport servers occasionally fail after consuming a lot of memory, rejecting all

messages and new connection attempts for a period of time, and then resumes normal functionality.
