Interview Questions and Answers
1)What are different Editions of Windows 2003 server?
i)Standard Edition
ii)Web Edition
iii)Enterprise Edition
iv)Datacenter Edition
2)What is active directory?
Active Directory is the directory service included in the Windows Server 2003 family. Active Directory includes the directory, which stores information about network resources, as well as all the services that make the information available and useful. Active Directory is also the directory service included in Windows 2000.
3)What is the active directory database name and where it is located?
Name : NTDS.Dit located in c:\windows\ntds\
4)What is the expantion of .Dit ? Scalable size of NTDS in 2k3?
.Dit – Directory Information Tree. It is scalable up to 70 TB.
5)What is schema in AD?
The Active Directory schema defines objects that can be stored in Active Directory. The schema is a list of definitions that determines the kinds of objects and the types of information about those objects that can be stored in Active Directory. Because the schema definitions themselves are stored as objects, they can be administered in the same manner as the rest of the objects in Active Directory. Normally called schema object or metadata .
6)Structure of AD in 2k3?
1)Physical structure
Sites ,Domain Controllers
2)Logical structures
Forest, Tree, Domain, OU
7)What are the domain functional levels in 2k3?
1)Mixed mode
2)Native mode
3)Interim mode
8)What is Global catalog and GC server?
The global catalog is the central repository of information about objects in a tree or forest. By default, a global catalog is created automatically on the initial domain controller in the first domain in the forest. A domain controller that holds a copy of the global catalog is called a global catalog server.
9)What are the functions of GC?
A)It enables a user to log on to a network by providing universal group membership information to a domain controller when a logon process is initiated.
B)It enables finding directory information regardless of which domain in the forest actually contains the data.
10)What is the active directory database engine name?
ESE (Extensible Storage Engine)
11)What are the partitions available in AD?
i)Schema partition
ii) Configuration Partition
iii) Domain Partition
iv)Application Partition
12)What are the two types of replications?
Inter-site(Site to site) and Intra-site(With in site) replications.
13)What is KCC ? What is the function of the KCC?
The KCC is a built-in process that runs on all domain controllers. The KCC configures connection objects between domain controllers. Within a site, each KCC generates its own connections. For replication between sites, a single KCC per site generates all connections between sites.
14)What are the two trust protocols 2k3 using ?
Kerberos V5 and NTLM
15)What are the trust relations available in 2k3?
Tree-Root , Parent- Child , Shortcut, Realm, Forest trust , External trust

It is applied from parent level to child level in AD.
i) Local GPO
ii) GPOs linked to sites
iii) GPOs linked to domains
iv) GPOs linked to OUs
17)What are the protocols used on replication?
RPC over IP (Used for synchronies transfer) , SMTP over IP (Asynchronies transfer)
18)What is the default time delay on replication?
Intra site – 15 min ( KCC automatically create the topology for Replication)
Inter-site – 1 hrs.
Security related changes replicated immediately across sites.
19)What Different tables available in NTDS database?
i)Schema table
ii)Link Table
iii)Data table
iv)Configuration Table
19)Where is the FRS logs stored in and what is the database engine name?
c:\windows\ntfrs\jet\log ,The engine used is jet database engine. Ntfrs.jdb.
20)What is tombstone object in AD? What is it’s life time?
Any objects deleted from Active directory will not removed from Database immediately. That object is called tombstone object. The default life time for that object is 60 days.For win 2k3 SP1 180 days
21) What are the FSMO roles in AD and what are the functionalities of those roles?
Every Active Directory forest must have the following roles:
1) Schema master 2) Domain naming master
These roles must be unique in the forest. This means that throughout the entire forest there can be only one schema master and one domain naming master.
Schema Master Role
The domain controller assigned the schema master role controls all updates and modifications to the schema. To update the schema of a forest, you must have access to the schema master. At any time, there can be only one schema master in the entire forest.
Domain Naming Master Role
The domain controller holding the domain naming master role controls the addition or removal of domains in the forest. There can be only one domain naming master in the entire forest at any time.
Domain-Wide Operations Master Roles
Every domain in the forest must have the following roles:
3)Relative identifier (RID), or relative ID, master 4) Primary domain controller (PDC) emulator 5) Infrastructure master
These roles must be unique in each domain. This means that each domain in the forest can have only one RID master, PDC emulator master, and infrastructure master.
RID Master Role
The domain controller assigned the RID master role allocates sequences of relative IDs to each of the various domain controllers in its domain. At any time, there can be only one domain controller acting as the RID master in each domain in the forest.
Whenever a domain controller creates a user, group, or computer object, it assigns the object a unique security ID. The security ID consists of a domain security ID (that is the same for all security IDs created in the domain) and a relative ID that is unique for each security ID created in the domain.
To move an object between domains (using Movetree.exe: Active Directory Object Manager), you must initiate the move on the domain controller acting as the RID master of the domain that currently contains the object.

Difference between Windows 2000 and 2003 Active Directory ?
Same structure; new capabilities
Unlike the transformation in the directory service architecture that took place between Windows NT and Windows 2000, the changes you see between Windows 2000 and Windows Server 2003 are much more incremental in nature. Windows Server 2003 is grounded in the same Active Directory structure in Windows 2000 where each domain controller holds a read-write copy of the AD database, relying on multi-master replication to keep everything up-to-date.
In the Windows Server 2003 Active Directory Users & Computers MMC snap-in, you can now move an object from one location in the directory tree to another by using the familiar drag-and-drop method, rather than being forced to right-click the object and select "Move", as was the case in Windows 2000. You can also now select multiple objects simultaneously for editing or deletion, and save commonly-used queries within the ADUC console window. Although really, if you're going to be working with more than one object at a time, I would recommend that you get out of the MMC console anyway and use command-line tools or scripts to take away some of your administrative burdens.
New command-line tools
Windows Server 2003 includes a number of built-in command-line tools that were not available in Windows 2000, including:
• dsadd -- allows you to create objects from the command line
• dsmove -- moves an object from one OU or container to another within the same domain
• dsrm -- will delete an object from Active Directory
• dsquery -- will return an object or list of objects that matches criteria that you specify
• dsget -- will return one or more attributes of a particular Active Directory object
Added feature promotes new domain controllers into a domain
Another new feature is the "Install from Media" option for promoting new domain controllers into a domain. In Windows 2000, if you needed to install a domain controller at a remote location, you had one of two options:
1. Travel to the remote site to running dcpromo and allow the entire AD database to replicate across a slow (and often expensive) WAN link, or
2. Configure the database at your corporate headquarters, and then ship the DC to the remote site; this is often an expensive process and one that runs the risk of damaging expensive computer hardware in transit.
Enter the "Install From Media" feature. In Windows Server 2003 you can initially populate the Active Directory database using a System State backup from an existing DC, saving you both WAN traffic and shipping costs. For those of us who run extremely decentralized environments, this is one of those "Where has this been all my life?" kinds of features.
Enhanced replication capabilities
Another significant change, particularly for larger environments, is a replication enhancement called linked-value replication for objects such as Active Directory group objects. In Windows 2000, a group's membership list was replicated as one single block of information. This led to a number of potential problems, such as the following:
1. Inconsistent replication. Consider this: you have a group called DOMAIN\Finance. From Domain Controller A, you add the jsmith user to the Finance group. What happens if, at precisely the same nanosecond, your junior admin removed the bthomas user from the Finance group while connected to Domain Controller B? Without linked-value replication, this would create a replication conflict, which would either lead to jsmith being added to the group and bthomas not being removed, or vice versa.
2. Replication delays. In Windows 2000, Microsoft published a size limitation where you could not place more than 5,000 members in a single group object; more than this created significant replication delays since the membership list was replicated as a single block.
Linked-value replication solves these problems by replicating these multi-valued attributes separately.
In our first example above, the addition of jsmith and the removal of bthomas would be replicated as two separate transactions, allowing both updates to be applied without causing a replication conflict. In our second example, only the individual changes to the group membership will be replicated, greatly streamlining the replication process and removing the 5000-member limitation on Active Directory groups.
