Windows Server 2003

There are five roles:

They are further classified in two

• Schema Master - As name suggests, the changes that are made while creation of any object in AD or changes in attributes will be made by single domain controller and then it will be replicated to another domain controllers that are present in your environment. There is no corruption of AD schema if all the domain controllers try to make changes. This is one of the very important roles in FSMO roles infrastructure.
• Domain Naming Master - This role is not used very often, only when you add/remove any domain controllers. This role ensures that there is a unique name of domain controllers in environment.

• Infrastructure Master - This role checks domain for changes to any objects. If any changes are found then it will replicate to another domain controller.
• RID Master - This role is responsible for making sure each security principle has a different identifier.
• PDC emulator - This role is responsible for Account policies such as client password changes and time synchronization in the domain

Hi, You cannot downgrade an operating system. You will have to nuke the hard drive and reload from the beginning. This is a tough one to do because you have to back-up everything you want to keep and make sure you have all the drivers for everything in your computer. Let me know if you have any questions. -Nitin Answer: Answer:

1: What you will receive: One copy of the applicable Windows Server downgrade software and associated product key. 2: The Downgrade Media Kit is not a new license for Windows Server. It may only be run under a valid license per the terms of those license terms. For example, a copy of Windows Server 2003 R2 Enterprise Edition may be run under a Windows Server 2008 license as permitted by the Downgrade rights described in that license. Check the applicable license terms for specific information regarding the rights for the license. 3: Transfer rights apply to the original license you purchased. 4: Only 1 downgrade media kit per license. 5: The terms of this offer may be changed at any time without notice including, without limitation, the expiration date. 6: There is a fee for this upgrade to cover materials, shipping, handling, and fulfillment overhead. The fee will vary depending on your location. The amount will be presented to you prior to final submission of your order. At that time, you will have the opportunity to opt out before final order submission. The fee is non-refundable. 7: OEM Customers: If you acquired your license with a new server from a server manufacturer, the downgrade software acquired through this program may not be supported by your OEM. Contact your server manufacturer for its support policy for running downgrade software on their server hardware.

DNS is extremely important to all aspects of proper Active Directory operation. Any time a client makes a request for a domain service, it must find a domain controller to service that request, which is where DNS comes in to play.

There are two types of DNS queries: recursive and iterative.

When a DNS client requests DNS information, it uses a recursive query to do so.

In a recursive query, the DNS client sends its query to the first DNS server that it has been configured for in its TCP/IP configuration. It then sits and waits for the server to return an answer. If the server returns a positive response, the client will then go to the IP address returned by the server.

First available in Windows 2003, you will create a copy of the system state from an existing DC and copy it to the new remote server. Run "Dcpromo /adv". You will be prompted for the location of the system state files

===================================

Answer B:

Backup system state as;

1. Click Start, click Run, type ntbackup, and then click OK. (If the Backup utility starts in wizard mode, click the Advanced Mode hyperlink.)
2. From the Backup tab, click to select the System State check box in the left pane. Do not back up the file system part of the SYSVOL tree separately from the system state backup.
3. In the Backup media or file name box, specify the drive, path, and file name of the system state backup.

Restore system stat as below on the target computer;

1. Log on to the Windows Server 2003-based computer that you want to promote. You must be a member of the local administrators group on this computer.
2. Click Start, click Run, type ntbackup, and then click OK. (If the Backup utility starts in wizard mode, click the Advanced Mode hyperlink.)
3. In the Backup utility, click the Restore and Manage Media tab. In the Tools menu, click Catalog a backup file..., and then locate the .bkf file that you created earlier. Click OK.
4. Expand the contents of the .bkf file, and then click to select the System State check box.
5. In Restore files to:, click Alternate Location. To restore the system state, type the logical drive and the path. We suggest that you type X:\Ntdsrestore. In this command, X is the logical drive that will ultimately host the Active Directory database when the member computer is promoted. The final location for the Active Directory database is selected when you run the Active Directory Installation Wizard. This folder must be different from the folder that contains the restored system state.

1. Verify that the domain controller that is to be promoted has DNS name resolution and network connectivity to existing domain controllers in the domain controller's target domain.
2. Click Start, click Run, type dcpromo /adv, and then click OK.
3. Click Next to bypass the Welcome to the Active Directory Installation Wizard and Operating System Compatibility dialog boxes.
4. On the Domain Controller Type page, click Additional domain controller for an existing domain, and then click Next.
5. On the Copying Domain Information page, click From these restored backup files:, and then type the logical drive and the path of the alternative location where the system state backup was restored. Click Next.
6. In Network Credentials, type the user name, the password, and the domain name of an account that is a member of the domain administrators group for the domain that you are promoting in.
7. Continue with the remainder of the Active Directory Installation Wizard pages as you would with the standard promotion of an additional domain controller.
8. After the SYSVOL tree has replicated in, and the SYSVOL share exists, delete any remaining restored system files and folders.

Note: There is Lot of difference win XP & win server 2003. Xp is a client operating systems. but win 2003 is a server. we can not install active directory in Xp. but we install active directorey win server 2003. we can not manage centralize Win xp. but we manage centralize Win server 2003. Win Xp use small network Maximum 25 computer in a network. but we manage large network through win server 2003.
