Section 2 Flashcards
Roles vs Features
Roles perform duties and do lots of things
Features are more of a tool you can use to get something done. Or a smaller part of a role that does one thing.
What is a domain?
What is a domain controller?
Domain - territory of control
Domain Controller - controls major group services:
User Activation (AD)
DNS
Print Services
File System Replication
Windows Time Service
DHCP
One primary server (primary domain controller) Computers are controlled by one that the other computers have to register with.
Domain Controller vs Active Directory
DC is just the main server that serves AD.
Active Directory (primary service role) - allows user to authenticate logins to login to clients.
Stores info about objects on network and makes info available. AD DS uses domain controllers to give net users access to permitted resources anywhere on net through single login process.
What is a requirement for domain controller installation?
You need a role service to install.
Like DNS or something, that would be domain controller role.
What’s the point of AD DS?
If you have a network of 10 computers and need to work on them, normally you’d have to add a user one computer at a time. Need to update a password? You’d have to do it one by one. AD DS makes it to where you have a one stop shop for authentication.
What is the NetBIOS Domain Name?
This is what you’d have to type in to access the domain. At work, we use humans\USERcred
Install Active Directory Domain Services but do the prerequisites first!
Confirm AD DS is on the system
mylabdc.local < -
LAB < netbios name
Verify DNS
Check your IP so your can reserve one that’s not being used, or just ping the ip
cmd > ipconfig
Settings > Network > Change Adapter settings > right click Ethernet (or whatever the adapter is called) > properties > TCP/IPv4 > Use the following. > Use the following DNS server address:
Just use default gateway.
Server Manager > Add Roles and Features > Select Active Directory Domain Services > Also select DNS > finish
Close
Click notification
Promote server to Domain Controller > Add a new forest > mylabdc.local > next > Enter Password for Domain admin account > next > next > NetBIOS name “LAB” > next > next > next > Install
Start > Windows Administrative Tools > Active Directory Users and Computers > Click your forest > Domain Controllers folder > you will see your computer.
ipconfig > double check your ip > Windows Administrative Tools > DNS > Click your pc > forward lookup Zones > mylabdc.local > lab-windows will show your entry for your static IP.
cmd > nslookup (ip) or ping lab-windows (whatever you named your computer.
What is a forest
AD runs on LDAP, what is that?
What is SYSVOL
AD Database - where is this saved
List Logical and Physical structures
Forest - Assembly of AD Domains that share a single schema for the AD. All DC’s in the forest share this schema and is replicated in hierarchical fashion among them. So same policies and rules and stuff are applied to all servers in the Domain.
LDAP - Lightweight Directory Access Protocol - Protocol used to lookup info or devices in network.
SYSVOL - Folder keeps server’s copy of the domain’s public files. Users, group policy, etc, of the sysvol folder are replicated to all domain controllers in the domain.
C:\Windows\ntds
Logical - Tree, forest, domain, OU
Physical - Domain Controller, Site
Define:
Organization Unit (OU)
Object
Attributes
OU - Subdivision of an Active Directory into which you can place users, group, computers, and other organizational units. Place where objects go.
Objects - User, Group, Contact, Computer, Shared Folder, Printer, etc.
Attributes - Objects have them and they describe them.
Example - a user object might have the name, e-mail and phone number attributes.
Go to users and computers and view the OUs
Where would you add a secondary domain controller
How do you create an object?
Navigate to your user and look at his properties
Server Manager > Tools > Active Directory Users and Computers
OR
start > windows admin tools > Active Directory users and computers > these are the folders under mylabdc.local that show a little notepad inside of them (Domain Controllers) <- you can add more DC here.
Right Click Domain Controllers or whatever OU you’re wanting to go into > new > whatever.
Users > right click user
What is an OU?
What is a sub-OU?
What is a group
These all fall under one domain
Defined by function. So like, we would be in IT for our OU, then our sub-ou might be systems, then our group would be like Linux
All the way down to our user in the Linux group.
Example - Seinfeld TV Show
OU - Seinfeld
sub-OU - Main cast, Parents, Friends, etc
group = parents > Jerry parents, George Parents
Users = Mory, Helen, etc
Check if you’re on the domain.
Go into Active Directory and create an OU for the IT team with sub OUs Systems and Network
Create Windows and Linux as groups in Systems
Create a user in Systems named James Paul
Add James Paul to the windows group
Confirm what groups James is a part of Do all the same for Sean Peters (speters) but for Linux
start > system and security > system > Check domain (or right click this pc and go to properties)
Start > Windows Admin tools > active directory users and computers > right click mylabdc.local > new > Organizational Unit > “IT” > uncheck protect container
Right click IT OU > New > Organizational Unit > Systems > do again for Network
Right Click Systems > New > Group > Name it Linux Do the same for Windows.
Right click systems > new > users > add user name > user login name (jpaul) > next > enter password > password never expires > next > finish
Right click Windows > properties > members (add) > type jpaul (login name)
Right click James Paul > properties > member of (this will show domain users and window)
Group scopes
Close enough for now:
Domain local - Only exposed to the domain locally
Global - Accounts from same domain as parent global group
Universal - Any domain in forest
What are the prerequisites for joining AD?
AD server should be up and running with a static IP
Client can reach AD
A user account should exist on AD that you will use once you’re registered.
How would you resolve your DNS’s hostname so we can ping it by name
Network and sharing > change adapter > Right click > properties > tcp/ipv4 properties > Use your Domain controller as the DNS server
ping mylabdc.local
