The easiest way to do this would be to bring up a new machine as a domain controller, it could be a temporary machine, a VM, a PC, anything. &nbsp;Transfer all the FSMO roles over to that machine. &nbsp;Verify replication, DNS, keep an eye on error logs. &nbsp;Demote the server that you plan on rebuilding. &nbsp;Rebuild it. &nbsp;Repromote it to a DC, transfer the roles back. &nbsp;Demote your temp machine.

Reinstall Domain controller (Exchange Environment)

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).
