According to the deployment guide: Before you install Exchange Server 2003, ensure that your network and servers meet the following system-wide requirements: � Domain controllers are running Windows 2000 Server Service Pack 3 (SP3) or Windows Server 2003. � Global catalog servers are running Windows 2000 SP3 or Windows Server 2003. It is recommended that you have a global catalog server in every domain where you plan to install Exchange 2003. � Domain Name System (DNS) and Windows Internet Name Service (WINS) are configured correctly in your Windows site. � Servers are running Windows 2000 SP3 or Windows Server 2003 Active Directory.
