30. What is the System Startup process?
Windows 2K boot process on Intel architecture.
1. Power-On Self Tests (POST) is run.
2. The boot device is found, the Master Boot Record (MBR) is loaded into memory, and its program is run.
3. The active partition is located, and the boot sector is loaded.
4. The Windows 2000 loader (NTLDR) is then loaded.
The boot sequence executes the following steps:
1. The Windows 2000 loader switches the processor to the 32-bit flat memory model.
2. The Windows 2000 loader starts a mini-file system.
3. The Windows 2000 loader reads the BOOT.INI file and displays the operating system selections (boot loader menu).
4. The Windows 2000 loader loads the operating system selected by the user. If Windows 2000 is selected, NTLDR runs NTDETECT.COM. For other operating systems, NTLDR loads BOOTSECT.DOS and gives it control.
5. NTDETECT.COM scans the hardware installed in the computer, and reports the list to NTLDR for inclusion in the Registry under the HKEY_LOCAL_MACHINE_HARDWARE hive.
6. NTLDR then loads the NTOSKRNL.EXE, and gives it the hardware information collected by NTDETECT.COM. Windows NT enters the Windows load phases.
31. What is WINS hybrid & mixed mode?
Systems that are configured to use WINS are normally configured as a hybrid (H-node) client, meaning they attempt to resolve NetBIOS names via a WINS server and then try a broadcast (B-node) if WINS is unsuccessful. Most systems can be configured to resolve NetBIOS names in one of four modes:
Broadcast (B-node)—Clients use a broadcast only to resolve names. An enhanced B-node setting has the client use an LMHOST file as well. The hex value for this setting is 0x1.
Peer-to-Peer (P-node)—Clients use WINS only to resolve names. The hex value for this setting is 0x2.
Mixed (M-node)—Clients first use a broadcast in an attempt to resolve NetBIOS names. If this fails, they attempt the resolution via the WINS server. The hex value for this setting is 0x4.
Hybrid (H-node)—Clients first use the WINS service in an attempt to resolve NetBIOS names. If this fails, they attempt the resolution via broadcast. The hex value for this setting is 0x8.
32. What is Disk Quota?
Disk Quota is the specifying the limits of usage on the disks.

1) What is 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.

Name : NTDS.Dit located in c:\windows\ntds\
4)What is the expansion 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 2kX?
1)Physical structure
Sites ,Domain Controllers
2)Logical structures
Forest, Tree, Domain, OU, object

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

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 is 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

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.

c:\windows\ntfrs\jet\log, The engine used is jet database engine. Ntfrs.jdb.
20) What is tombstone object in AD? What is its 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) FSMO Roles
In a forest, there are at least five FSMO roles that are assigned to one or more domain controllers. The five FSMO roles are
Schema Master:
The schema master domain controller controls all updates and modifications to the schema. To update the schema of a forest, you must have access to the schema master. There can be only one schema master in the whole forest.
Domain naming master
The domain naming master domain controller controls the addition or removal of domains in the forest. There can be only one domain naming master in the whole forest.
Infrastructure Master:
The infrastructure is responsible for updating references from objects in its domain to objects in other domains. At any one time, there can be only one domain controller acting as the infrastructure master in each domain.
Relative ID (RID) Master:
The RID master is responsible for processing RID pool requests from all domain controllers in a particular domain. At any one time, there can be only one domain controller acting as the RID master in the domain.
PDC Emulator
The PDC emulator is a domain controller that advertises itself as the primary domain controller (PDC) to workstations, member servers, and domain controllers that are running earlier versions of Windows.
For example, if the domain contains computers that are not running Microsoft Windows XP Professional or Microsoft Windows 2000 client software, or if it contains Microsoft Windows NT backup domain controllers, the PDC emulator master acts as a Windows NT PDC.
It is also the Domain Master Browser, and it handles password discrepancies. At any one time, there can be only one domain controller acting as the PDC emulator master in each domain in the forest

Quicker Q&A
What are the required components of Windows Server 2003 for installing Exchange 2003? - ASP.NET, SMTP, NNTP, W3SVC
What must be done to an AD forest before Exchange can be deployed? - Setup /forestprep
What Exchange process is responsible for communication with AD? - DSACCESS
What 3 types of domain controller does Exchange access? - Normal Domain Controller, Global Catalog, Configuration Domain Controller
What connector type would you use to connect to the Internet, and what are the two methods of sending mail over that connector? - SMTP Connector: Forward to smart host or use DNS to route to each address
How would you optimise Exchange 2003 memory usage on a Windows Server 2003 server with more than 1Gb of memory? - Add /3Gb switch to boot.ini
What would a rise in remote queue length generally indicate? - This means mail is not being sent to other servers. This can be explained by outages or performance issues with the network or remote servers.
What would a rise in the Local Delivery queue generally mean? - This indicates a performance issue or outage on the local server. Reasons could be slowness in consulting AD, slowness in handing messages off to local delivery or SMTP delivery. It could also be databases being dismounted or a lack of disk space.

========================================================
1. What are the Default shares in Windows Server 2003?
By default, Windows automatically creates special hidden administrative shares that administrators, programs, and services can use to manage the computer environment or network. These special shared resources are not visible in Windows Explorer or in My Computer, but you can use the Shared Folders tool in Computer Management to view them. Depending on the configuration of your computer, you may see some or all the following special shared resources listed in the Shares folder in Shared Folders:
•
DriveLetter$: Root partitions and volumes are shared as the drive letter name appended with the $ character. For example, drive letters C and D are shared as C$ and D$.
•
ADMIN$: A resource that is used during remote administration of a computer.
•
IPC$: A resource that shares the named pipes that you must have for communication between programs. Note that this resource cannot be deleted.
•
NETLOGON: A resource that is used on domain controllers.
•
SYSVOL: A resources that is used on domain controllers.
•
PRINT$: A resource that is used during the remote administration of printers.
•
FAX$: A shared folder on a server that is used by fax clients during fax transmission.
Note NETLOGON and SYSVOL are not hidden shares but are instead special administrative shares. Generally, Microsoft recommends that you do not modify these special shared resources. However, if you want to remove the special shared resources and prevent them from being created automatically, you can do this by editing the registry.
1. Q) Can I changed password if my machince’s connectivity to DC who holds PDC emulator role has been fails?A) No You cant the password.
Q) i have been asked if there is set of 30 harddisk configured for raid 5 if two harddisk failed what about dataA) It depends how u had configured ur RAID its only Raid5 or with with spare if its only raid 5 then in raid5 if ur 2 nos of HDD goes then ur raid is gone.
Q) How Can i Deploy the Latest Patched in Pc through G.P. wihtout having the Admin Right in Pc.A) Create a batch file and place all the patches in the Netlogon, and deploy the batch file through GP to all the pcs so the same should take affect after restarting the pc.
Q) In Raid 5,Suppose i have 5 HDD of 10-10 GB, After configuring the Raid how much space do i have for utilise.A) -1 out of the total (eg- if u r using 5 u will get only 4 because 1 goes for parity).
Q) How Can i Resolve the Svr name through NslookupA) what exactly u want to do, nslookup command will let u know through which server u r getting routed, (eg- c:\nslookup then u will get ur domain name to which u r getting routed. and if u want to get the name of the pc/server with the ip address then u have to give the command c:\nbtstat -a ip xx-xx-xx-xx)

Question: What is Multi Master Replication?
Answer: Multi-master replication is a method of replication employed by databases to transfer data or changes to data across multiple computers within a group. Multi-master replication can be contrasted with a master-slave method (also known as single-master replication).
DFS? DFS Namespace ?
1. DFS Replication. New state-based, multimaster replication engine that is optimized for WAN environments. DFS Replication supports replication scheduling, bandwidth throttling, and a new byte-level compression algorithm known as remote differential compression (RDC).
DFS Namespaces. Technology that helps administrators group shared folders located on different servers and present them to users as a virtual tree of folders known as a namespace. DFS Namespaces was formerly known as Distributed File System in Windows 2000 Server and Windows Server 2003.
What are the four domain functional levels?
Windows 2000 MixedWindows 2000 NativeWindows Server 2003 InterimWindows Server 2003
Windows 2000 Mixed
When you configure a new Windows Server 2003 domain, the default domain functional level is Windows 2000 mixed.Under this domain functional level, Windows NT, 2000, and 2003 domain controllers are supported. However,certain features such as group nesting, universal groups, and so on are not available.
Windows 2000 Native
Upgrading the functional level of a domain to Windows 2000 Native should only be done if there areno Windows NT domain controllers remaining on the network. By upgrading to Windows 2000 Native functional level,additional features become available including: group nesting, universal groups, SID History, and the ability to convertsecurity groups and distribution groups.
Windows Server 2003 Interim
The third functional level is Windows Server 2003 Interim and it is often used when upgrading fromWindows NT to Windows Server 2003. Upgrading to this domain functional level provides support forWindows NT and Windows Server 2003 domain controllers. However, like Windows 2000 Mixed, it does not provide new features.
Windows Server 2003The last functional level is Windows Server 2003. This domain functional level only provides support forWindows Server 2003 domain controllers. If you want to take advantage of all the features included withWindows Server 2003, you must implement this functional level. One of the most important features introducedat this functional level is the ability to rename domain controllers
