MS Exchange Server 2003 Question:
What is the difference between Exchange 2003 and Windows 2003?
Answers:
Answer #1Windows Server 2003 provides significant enhanced functionality that Exchange 2003 takes advantage of:
Outlook HTTP access:
IIS 6.0 and Windows RPC Proxy service in Windows Server 2003 enable communication between Outlook 2003 and Exchange Server 2003 by means of HTTP. Outlook 2003 users can synchronize directly with the server running Exchange Server 2003 over a HTTP or HTTPS connection.
Internet protocol support:
IIS 6.0 provides Exchange with its support for many common Internet access protocols that increase the flexibility of the operating system, such as HTTP, Post Office Protocol version 3 (POP3), Internet Message Access Protocol version 4 (IMAP4), and Simple Mail Transfer Protocol (SMTP).
Active Directory:
Windows provides Active Directory, upon which Exchange depends for user information, mail routing information, user authentication, and LDAP read and write functions.

Answer #2Support for clustering:
Exchange Server 2003 provides better support for clustering, which enables high availability of a company’s infrastructure. Customers can choose to run up to 8-node clusters, with at least one passive node, when running Exchange 2003 on Windows Server 2003, Enterprise Edition. (In Windows 2000 Advanced Server, clustering was limited to two nodes, one active and one passive; if a company chose to run Windows 2000 Datacenter Server, clustering was limited to four nodes.)
Volume Shadow Copy service:
This and Virtual Disk Service are part of a storage framework that provides heterogeneous interoperation of storage hardware, storage software, and applications. Exchange 2003 writes to the Volume Shadow Copy service on Windows Server 2003, reducing dramatically the backup and restore times for Exchange messaging environments. This enables IT departments to support greater numbers of users per server and reduces the total number of servers running Exchange in their environment.
