Introduction
Domains provide an easier way for Administrators to manage Accounts, Permissions and Security for a large network.
Domain Basics
Domain controllers provide access keys to clients to allow or restrict access to network resources
Single place to administer permissions and security
Permissions and Security can be assigned to: Users, Groups, Organization Units
Permissions mean access to shared resources such as files, folders and printers. Security means restrictions about changing desktop background, password policies, access to local drives.
Ways to Have a doming
Windows is the standard type of domain environment
SAMBA -- Linux version of a PDC
Novell -- Still exists...
You need a business class Windows Operating System to join a domain. XP Pro, Vista Business / Ultimate, 7 Business / Ultimate
Domain Controllers
PDC/ BDC Structure. The PDC has a read and write copy of the security database. If the PDC fails a BDC will provide security information to the network. The BDC has a READ only copy of the database and so administrators cannot change user permissions on a BDC. A BDC can be promoted to a PDC. There is only one PDC in a domain at a time.
Active Directory. All Domain Controllers have read and write access (Theoretically, this can be modified).
Structure
Trusts allow users from one Domain to log on to computer in another Domain. Small offices would never need this. This is for large corporations that own numerous companies. If the Geek from the parent company needs to do work on the computers at the child company a trust relationship between the domains would be created.
There are multiple types of Trusts: One Way, Two Way, Transient
Final Thoughts
Domains are a great tool for large networks, but they require specialized computer technicians and equipment. Depending on the cost/ benefit analysis they may not be a good idea for small networks.

When you say that you need windows 7 business edition or ultimate edition to add a computer to your domain. Is business edition the same as proffesional edition?

And thank you so much for making thees videos. Its helping me allot with my studies for my exam in IT network drifting. Having adhd and trouble concentrating while reading, watching your comprehensive easy to follow videos is a great addition to the books I am reading at the moment.

@Durd3n001 It's Windows 7 Professional... One of the pains of dealing with Microsoft is they change the names of their products with every edition... Basically you just need the "business" edition of the OS. (NT vs 98, XP Pro vs. XP Home, Vista Business vs. Home Premium, 7 Pro vs. Home Premium...)

[sanders555]

This might be a dumb question but when you refer to multiple domain controllers (like 5) - or PDC vs BDC - are you referring to multiple controllers running on one machine or is there one controller running on each server?

[elithecomputerguy]

@sanders555 Each server would be a Domain Controller or DC.

[algnadjib]

can the users log on from any computer to a network with a domain ?

i mean, can the user ELI enter from COMPUTER1 and COMPUTER2 to the network with the same username and pass

[elithecomputerguy]

@algnadjib yes... that's one of the main purposes of a Domain.
