One of the really exciting new ones is the concept of the read-only domain controller. Before with AD, as compared with NT 4.0 in particular, every domain controller has a writable copy of your directory. You can make a change anywhere and it will propagate throughout the environment. At the same time, all of [the domain controllers] have secrets like your password. Right now with Windows Server 2003, if that server security is physically compromised and gets stolen and it's not secure, then you have a huge security issue in that all the password for that domain are in the DNCs. So the only approach you can take is to make everyone change their password. That's a big deal if you have 100,000 people on that domain.
With the new read-only domain controller feature, this change is two-fold. First you can now define which passwords are stored locally. Now if the server gets stolen, you only have to have 100 people change their passwords versus 100,000.
Second, you can't make any changes on that domain controller (DC), because it's read only.
1.we can install windows 2008 server either in full version(install all services& applications) or server core(only install minimal required services), but in 2003 we can only install fully O.S.
2.Windows server 2008 use Hyper-V application & Roles concept for better productivity but server 2003 does not have such features.
1)2008 is combination of vista and windows 2003r2. Some new services are introduced in it
1. RODC one new domain controller introduced in it
[Read-only Domain controllers.]
2. WDS (windows deployment services) instead of RIS in 2003 server
3. shadow copy for each and every folders
4.boot sequence is changed
5.installation is 32 bit where as 2003 it is 16 as well as 32 bit, that's why installation of 2008 is faster
6.services are known as role in it
7. Group policy editor is a separate option in ads
2) The main difference between 2003 and 2008 is Virtualization, management.
2008 has more inbuilt components and updated third party drivers Microsoft introduces new feature with 2k8 that is Hyper-V Windows Server 2008 introduces Hyper-V (V for Virtualization) but only on 64bit versions. More and more companies are seeing this as a way of reducing hardware costs by running several 'virtual' servers on one physical machine. If you like this exciting technology, make sure that you buy an edition of Windows Server 2008 that includes Hyper-V, then launch the Server Manger, add Roles.
3) In Windows Server 2008, Microsoft is introducing new features and technologies, some of which were not available in Windows Server 2003 with Service Pack 1 (SP1), that will help to reduce the power consumption of server and client operating systems, minimize environmental byproducts, and increase server efficiency.
Microsoft Windows Server 2008 has been designed with energy efficiency in mind, to provide customers with ready and convenient access to a number of new power-saving features. It includes updated support for Advanced Configuration and Power Interface (ACPI) processor power management (PPM) features, including support for processor performance states (P-states) and processor idle sleep states on multiprocessor systems. These features simplify power management in Windows Server 2008 (WS08) and can be managed easily across servers and clients using Group Policies

How Active directory looks in network?
Active Directory on a Windows Server 2003 Networkhttp://technet.microsoft.com/en-us/library/cc780036.aspx
When did active directory come out?
Active Directory was previewed in 1999, released first with Windows 2000 Server edition, and revised to extend functionality and improve administration in Windows Server 2003. Additional improvements were made in Windows Server 2003 R2. Active Directory was refined further in Windows Server 2008 and Windows Server 2008 R2 and was renamed Active Directory Domain Services. Active Directory was called NTDS (NT Directory Service) in older Microsoft documents. This name can still be seen in some Active Directory binaries.
What is the file name of active directory in windows server 2003?
ntds.dit
Where active directory store its own data in server 2003?
NTDS.DIT
How do you create active directory in windows server 2003?
Just run 'dcpromo'.
Which network operating system is best for active directory?
Windows 2003 Server is the Best
What is DCDIAGexe?
DCDiag is a utility program used in Windows Server 2003 and above for diagnosing problems with AD (Active Directory). It can be used to test problems with Active Directory as well as diagnosing DNS problems.
How many users are create in active directory window 2003?
10 mllion users.because active directory support 10 million objects if you do not create any OU,Any shared Folder or other object.
A logical diagram showing active directory in windows 2000 server architecture?

What are several of the largest advantages of using active directory integrated zones as a type for a larger organization?
The main zone types used in Windows Server 2003 DNS environments are primary zones and Active Directory-integrated zones. Both primary zones and secondary zones are standard DNS zones that use zone files. The main difference between primary zones and secondary zones is that primary zones can be updated. Secondary zones contain read-only copies of zone data.An Active Directory-integrated zone can be defined as an improved version of a primary DNS zone because it can use multi-master replication and the security features of Active Directory. The zone data of Active Directory-integrated zones are stored in Active Directory.Active Directory-integrated zones are authoritative primary zones.A few advantages that Active Directory-integrated zone implementations have over standard primary zone implementations are:Active Directory replication is faster, which means that the time needed to transfer zone data between zones is far less.The Active Directory replication topology is used for Active Directory replication, and for Active Directory-integrated zone replication. There is no longer a need for DNS replication when DNS and Active Directory are integrated.Active Directory-integrated zones can enjoy the security features of Active Directory.The need to manage your Active Directory domains and DNS namespaces as separate entities is eliminated. This in turn reduces administrative overhead.When DNS and Active Directory are integrated; the Active Directory-integrated zones are replicated, and stored on any new domain controllers automatically. Synchronization takes place automatically when new domain controllers are deployed
What active directory domain services are not installed on a Windows server 2008 computer until you install AD DS role to the computer?
The DNS Server Role and the active directory is not installed till the adds service is started on the server 2008.if the service is not started(one needs to check the option under roles of the server)the active directory installation wont happen.this feature is only in 2008 not in 2003.The active directory works as service in 2008
Which edition of Windows Server 2003 cannot be configured as an Active Directory domain controller?
Windows Server 2003, Web Edition
