Class Notes

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.

Eli the Computer Guy.. This video was uploaded back in 2011 and yet it came to use for me. I've just landed a desktop support position and have been hitting the books so I am prepared for anything. Thank you so much for the free lessons. Keep being you!

Seriously I saw that this video was about an hour long and I almost did not watch it because I am working and did not think I had the time. I am glad I did because this was soooo helpful in helping me understand domains, which prior to watching this video my understanding was blurry. Thanks for taking the time ti describe. I have to audit networks and understanding domains and their function helos a great deal. I just subscribed. Awesome video for beginners

Eli, just would like to thank you for all of your kindness and dedication on sharing your, so vast, knowledge. I'm getting into the servers right now and trying out the samba server that became very much like you said, it may or may not work well with windows. If you have some good sources (easier to understand) about the subject or you have a video you already did or plan to do, please let us know it! Again, thank you so much for the simple language and easy to understand conceptual class!!!!
