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
