Hi vickeyab!

Why do I have a feeling that this is some kind of homework?

Hmmm... I agree on the homework thing, but a few things should be corrected, more for Vishal_impact than anyone else.

> ***What is Active Directory?

Simply put Active Directory is an LDAP compliant Directory Service (X.500) used to store information about a network. It's main purpose is to provide centralised authentication and management.

While it relies on DNS heavily, it is not built on DNS. DNS is used to store Service Locator Records which are used by clients to locate the services provided by the domain (including Kerberos authentication services, and Directory Services for information retrieval).

> **Can you connect Active Directory to other 3rd-party Directory  Services? Name a few options.

Yes. Microsoft Identity Integration Server (MIIS) is one of the options you can use to act as an intermediary between two directories (including directories used by SAP, Domino, etc).

> ***Where is the AD database held? What other folders are related to AD?

NTDS.DIT is our main Database file. It's stored (by default) in C:\Windows\NTDS

Other folders would include SYSVOL, and perhaps NETLOGON (even though it's a sub-folder of SYSVOL it's important as a share).

> **What is the SYSVOL folder?

Correctly termed System Volume, primarily used for Group Policies and Scripts.

> **Name the AD NCs and replication issues for each NC

NC is Naming Context. There are 5 of these in Windows 2003 Domains / Forests to consider:

Directory - Replicated to all DCs in the Domain
Configuration - Replicated to all DCs in the Forest
Schema - Replicated to all DCs in the Forest
DomainDNSZones - Replicated to all Windows 2003 DC / DNS Servers in the Domain
ForestDNSZones - Replicated to all Windows 2003 DC / DNS Servers in the Forest

I know, I know, homework and all that, but...
