Here is some of the short bullet point for the core concept
- Active Directory is a directory service, it is DataBase ( NTDS.DIT)
- Domain: Boundary of Authentication
- Domain: Boundary of DNS name space
- Domain: Boundary of replication
- Domain Controller: Authentication Server
- Schema: Definition of an Object
- Object: User, printer, OU, Group
- Attribute: properly of an Object
- Tree: Contiguous namespace
- OU : Active Directory Object
Active Directory Naming is based on Lightweight Directory Application Protocol (RFC 1777)
Domain Name service & System (DNS).
DC | Domain Component |
O | Organization |
OU | Organization Unit |
CN | Command Name |
Tree: Hierarchy if Domains forming a contiguous namespace, mapping the DNS infrastructure
FSO Roles (Operation Masters) or DR PIS as Thomas Called today in our MCSE Class , What can I say you the MAN Thomas (-:
Having trouble to remembering FSMO Roles, After Thomas advice you will never forget DR PIS? (Doctor PIS)
D | Domain Naming Master | 1 per forest | Controls the addition and removal of domains from the forest |
R | RID Master | 1 per domain | Allocates pools of unique identifiers to domain controllers for use when creating objects |
P | PDC Emulator | 1 per domain | Provides backwards compatibility for NT4 clients for PDC operations (like password changes). The PDC Emulator also runs domain specific processes such as the Security Descriptor Propogator (SDPROP), and is the master time server within the domain |
I | Infrastructure Master | 1 per domain | Synchronizes cross-domain group membership changes. The infrastructure master cannot run on a global catalog server (unless all DCs are also GCs.) |
S | Schema Master | 1 per forest | Controls updates to the Schema |
If you have 12 Domain in a same forest how may FSMO roles you will have?
Let's do the math
Answer: 38
Primary functions of OU |
Delegate permissions |
Organize Objects |
Deploy Group policies |
In which order Group Polices gets installed?
L | Local |
S | Site |
D | Domain |
O | OU |
