Windows 2003 Overview Lecture 1

Windows Networking Evolution Windows for Workgroups – peer-to-peer networking built into the OS Windows NT – separate server and client versions, emphasis on client/server model, improved security, NTFS Windows 2000 – improved interface, reliability and manageability, Active Directory Windows 2003 – server only, “face-lift” - improved interface and management features

Windows 2003 R2  Minor revision  Based on Server 2003 SP1  Optimized for remote server (branch office) management  See other new features herehere  Latest Service Pack for 2003 R2 Server is SP2

Windows Server roadmap  Windows Server release cycle – plan is to issue major upgrades (kernel change) every 4 years, minor releases every 2 years.  Windows Vista is the latest desktop version of Windows (released 1/29/2007) and Windows Server 2008 (released 2/27/2008) is the latest server version.  Microsoft will provide Mainstream support for 2003 Server until July 13, Then Windows Server 2003 and Windows Server 2003 R2 will transition from the Mainstream Support phase to the Extended Support phase.

Windows 2003 Workgroups, Domains and AD Workgroups Vs Domains - Workgroup – logical grouping of network devices for resource sharing; peer-to-peer arrangement; decentralized - Domain – logical grouping of network devices for resource sharing; centralized authentication and management of resources

Windows 2003 Workgroups Workgroups: User accounts are created on each computer (local account database) No centralized management or security Duplication of accounts on each computer Ideal for small groups of technically capable users

Windows 2003 Domains User accounts are centralized in the common database Central security and resource management A user only needs one account to access all resources Require a server to be a domain controller Need careful planning and design Computers need to join the domain Each computer still maintains its own local user database

Active Directory Centralized data store Hierarchical, tree-like structure Everything is represented as an object Centralized security and authentication Centralized management and administration Expandable, scalable
