Do you mean internet bandwidth? <br />
If so, then you need to start looking at what happens at that time. AV software doing updates would be one guess, backup software going to the cloud, user synchronising something large which doesn't complete. <br />
There is nothing in Exchange that could do it.<br />

Recently my exchange box started taking all of my bandwidth starting at a specific time?  I need to reboot the server and then all is fine "for now".  Once it starts, it consumes all of my bandwidth and everything stops (goes to a crawl) and renders the network useless.

Exchange 2003 server taking all my bandwith at a specific time every other morning

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
