2.0 Installing and Configuring Active Directory Domain Service (AD DS) and DNS When you create a new Active Directory Domain Services (AD DS) domain, the Active Directory Domain Services Installation Wizard installs the Domain Name System (DNS) server role by default. This ensures that DNS and AD DS are configured properly for integration with each other. Important Before you install AD DS and DNS on the first domain controller server in a new domain, ensure that the IP address of the server is static; that is, that it is not assigned by Dynamic Host Configuration Protocol (DHCP). DNS servers and Active Directory domain controllers must have static addresses to ensure that clients can locate the servers reliably. To install DNS with AD DS in a new domain 1. Click Start, point to Administrative tools, and then click Server Manager. 2. In the tree pane, click Roles. 3. In the results pane, click Add Roles.

4. On the Before You Begin page, click Next. 5. On the Select Server Roles page, click Active Directory Domain Services, and then click Next.

6. On the Active Directory Domain Services page, read the information and then click Next. 7. On the Confirm Installation Selections page, read the information and then click Install. 8. After AD DS installation has completed, on the Installation Results page, click Close this wizard and launch the Active Directory Domain Services Installation Wizard (dcpromo.exe). 9. On the Welcome to the Active Directory Domain Services Installation Wizard page, click Next. 10. On the Choose a Deployment Configuration page, click Create a new domain in a new forest, and then click Next. 11. On the Name the Forest Root Domain page, type the full DNS name (such as for the new domain, and then click Next.

12. On the Set Forest Functional Level page, select Windows Server 2008, and then click Next. 13. On the Additional Domain Controller Options page, make sure that DNS server is selected, and then click Next.

Note A message box informs you that a delegation for this DNS server cannot be created.

This is normal and expected for the first domain controller in a new forest. Click Yes to proceed.

14. On the Location for Database, Log Files, and SYSVOL page, type the location in which you want to install the database, log, and system volume (SYSVOL) folders, or click Browse to choose a location, and then click Next. Note You can safely accept the default locations unless you know that you have a reason to change them.

15. On the Directory Services Restore Mode Administrator Password page, type a password to use to log on to the server in Directory Services Restore Mode, confirm the password, and then click Next.

16. Review the Summary page, and then click Next to begin the installation. 17. After the AD DS installation completes, click OK to restart the computer.

Configuring Client Settings By default, Domain Name System (DNS) clients are configured to allow Dynamic Host Configuration Protocol (DHCP) to automatically assign the clients' IP addresses, DNS server addresses, and other settings. The TCP/IP configuration steps in this section are required only if a DHCP server is not available. Configure the following settings for each DNS client: TCP/IP settings for DNS Host name and domain membership The following procedures require you to log on with an account that belongs to the Administrators group on the client computer. To configure client settings on a computer running Windows XP 1. On the computer that you want to configure to use DNS, click Start, point to Control Panel, and then click Network Connections. 2. Right-click the network connection that you want to configure, and then click Properties. 3. On the General tab, click Internet Protocol (TCP/IP), and then click Properties.

4. Click Use the following IP address. 5. In IP address, type the address of the client computer. 6. In Subnet mask, type the subnet mask of the domain controller. 7. In Default gateway, type the address of the default gateway of the domain controller. 8. Click Use the following DNS server addresses. 9. In Preferred DNS server, type the IP address of the DNS server that you installed in Installing and Configuring AD DS and DNS. Important Do not use the IP address of a DNS server that is provided by your Internet service provider (ISP) as a primary or alternate DNS server. 10. Click OK, and then click Close. Note It is not necessary to restart the computer at this time if you intend to change the computer's name or domain membership in the following steps. 11. In Control Panel, double-click System. 12. On the Computer Name tab, click Change. 13. In Computer name, type the name of the computer (the host name). 14. Click Domain, and then type the name of the domain that you want the computer to join.

15. If a second Computer Name Changes dialog box appears, in User Name, type the domain name and user name of an account that has permission to join computers to the domain. 16. In Password, type the password of the account. Separate the domain name and user name with a backslash, for example, domain\user_name.

17. Click OK to close all dialog boxes.

Advanced DNS Configuration In most cases, deploying Active Directory Domain Services (AD DS)–integrated Domain Name System (DNS) on a small, Windows-based network requires little configuration beyond the initial setup. Occasionally, however, you may have to perform additional configuration tasks, such as adding resource records to handle unusual situations or configuring automatic removal of outdated resource records.

Adding resource records Resource records store information about specific network computers, such as the names, IP addresses, and services that the computers provide. In most cases, Windows-based computers use dynamic update to update their resource records on DNS servers. This dynamic update process eliminates the need for an administrator to manage the resource records. However, if your network contains computers that are not Windows-based or if it contains computers that you want to designate to handle e-mail, you may have to add host (A) resource records to the zone on your DNS server. Important When the Active Directory Domain Services Installation Wizard installs and configures DNS on the new domain controller, it creates resource records that are necessary for the correct operation of the DNS server on the domain controller. Do not remove or change these resource records. Change or remove only those resource records that you add yourself. Host (A) resource records associate the DNS domain name of a computer (or host) to its IP address. You do not need to have a host (A) resource record for all computers, but you must have one for any computer that shares resources on a network and that must be identified by its DNS domain name. Windows 2000, Windows XP, and Windows Server 2003 clients and servers use the Dynamic Host Configuration Protocol (DHCP) Client service to dynamically register and update their host (A) resource records in DNS when an IP configuration change occurs. Windows Vista and Windows Server 2008 clients use the DNS Client service to dynamically register and update their host (A) resource records in DNS when an IP configuration change occurs. You can manually create a host (A) resource record for a static TCP/IP client computer (or for a computer running non-Windows operating systems) by using the DNS Manager administrative tool. To add a host (A) resource record to a DNS zone 1. On the DNS server, click Start, point to Administrative Tools, and then click DNS. 2. In the console tree, right-click the applicable DNS zone, and then click New Host (A). 3. In Name (uses parent domain if blank), type the name of the computer (host) for which you are creating a host (A) resource record. 4. In IP address, type the address of the computer for which you want to create a host (A) resource record. Important Make sure that you type the address correctly and that you assign it as a static address (not one that is assigned by DHCP). If the address is incorrect or changes, client computers cannot use DNS to locate the host.

2.1 Configuring Microsoft Hyper-V and preparing to server virtualization

Hyper-V™ is a new role in Windows Server® 2008 that provides you with the tools and services you can use to create a virtualized server computing environment. This guide introduces Hyper-V by providing instructions for installing this role and configuring a virtual machine for testing purposes. Hyper-V Operating System Requirements Hyper-V is only available bundled with the 64-bit (x64) version of Windows Server 2008. It is not available with the 32-bit version of Windows Server 2008, nor is it available for any other members of the Windows operating system family. Availability is further limited to the Standard, Enterprise and Datacenter versions of Windows Server 2008 (Hyper-V is not included with Windows Server 2008 Web Edition). Hyper-V is available in both Windows Server 2008 Full and Core installations. Hyper-V CPU Requirements As indicated in the previous section, a 64-bit CPU is required by Hyper-V. 64-bit processors from both Intel and AMD are supported (excluding Itanium), although the processors must support a number of key virtualization features in order for Hyper-V to run.  Hardware assisted virtualization - Processors with support for hardware assisted virtualization provide an additional privilege mode above ring 0 (referred to ring -1) in which the hypervisor can operate, essentially leaving ring 0 available for guest operating systems to run. Processors with Intel VT or AMD-V support include hardware assisted virtualization.  Hardware based Data Execution Prevention - Hardware based Data Execution Prevention (DEP) allows the processor to mark sections of memory as non-executable. This feature is available in processors with AMD NX and Intel XD support. Details of the CPU type installed in a system can be obtained from the hardware vendor. Specific CPU features are available in the specification provided by the CPU manufacturer. Enabling Hardware Assisted Virtualization Although a CPU may include hardware assisted virtualization support, this feature is not enabled in default factory settings on many systems. If Hyper-V indicates during installation that the host system's CPU type does not support virtualization, restart the system, enter the BIOS configuration menu and ensure that the appropriate virtualization feature is enabled. Hyper-V Memory Requirements In order to deploy Hyper-V virtualization on a server it is essential that the system have sufficient memory to host both the parent partition (which requires a minimum of 1GB of RAM) and the guest virtual machines. The precise requirements will depend on the number of virtual machines that will be run concurrently, further taking into consideration the memory needs of each specific virtual machine. Networking Requirements Virtual machines will use the physical network adapters installed into the host system to communicate with the external network. If the host system is to be managed remotely, an additional network adapter will need to be installed for this purpose.

Step 1: Install Hyper-V You can use Server Manager to install Hyper-V. To install Hyper-V 1. Click Start, and then click Server Manager. 2. In the Roles Summary area of the Server Manager main window, click Add Roles. 3. On the Select Server Roles page, click Hyper-V. 4. On the Create Virtual Networks page, click one or more network adapters if you want to make their network connection available to virtual machines. 5. On the Confirm Installation Selections page, click Install. 6. The computer must be restarted to complete the installation. Click Close to finish the wizard, and then click Yes to restart the computer. 7. After you restart the computer, log on with the same account you used to install the role. After the Resume Configuration Wizard completes the installation, click Close to finish the wizard. Step 2: Create and set up a virtual machine After you have installed Hyper-V, you can create a virtual machine and set up an operating system on the virtual machine. Before you create the virtual machine, you may find it helpful to consider the following questions. You can provide answers to the questions when you use the New Virtual Machine Wizard to create the virtual machine.  Is the installation media available for the operating system you want to install on the virtual machine? You can use physical media, a remote image server, or an .ISO file. The method you want to use determines how you should configure the virtual machine.

How much memory will you allocate to the virtual machine?

 Where do you want to store the virtual machine and what do you want to name it?

To create and set up a virtual machine 1. Open Hyper-V Manager. Click Start, point to Administrative Tools, and then click Hyper-V Manager. 2. From the Action pane, click New, and then click Virtual Machine. 3. From the New Virtual Machine Wizard, click Next. 4. On the Specify Name and Location page, specify what you want to name the virtual machine and where you want to store it. 5. On the Memory page, specify enough memory to run the guest operating system you want to use on the virtual machine. 6. On the Networking page, connect the network adapter to an existing virtual network if you want to establish network connectivity at this point. Note If you want to use a remote image server to install an operating system on your test virtual machine, select the external network. 7. On the Connect Virtual Hard Disk page, specify a name, location, and size to create a virtual hard disk so you can install an operating system on it. 8. On the Installation Options page, choose the method you want to use to install the operating system:  Install an operating system from a boot CD/DVD-ROM. You can use either physical media or an image file (.iso file).  Install an operating system from a boot floppy disk.  Install an operating system from a network-based installation server. To use this option, you must configure the virtual machine with a network adapter connected to the same network as the image server. 9. Click Finish. After you create the virtual machine, you can start the virtual machine and install the operating system.

Step 3: Install the operating system and integration services In the final step of this process, you connect to the virtual machine to set up the operating system. As part of the setup, you install a software package that improves integration between the virtualization server and the virtual machine. Note The instructions in this step assume that you specified the location of the installation media when you created the virtual machine. The instructions also assume that you are installing an operating system for which integration services are available. To install the operating system and integration services 1. From the Virtual Machines section of the results pane, right-click the name of the virtual machine you created in step 2 and click Connect. The Virtual Machine Connection tool will open. 2. From the Action menu in the Virtual Machine Connection window, click Start. 3. Proceed through the installation. Notes  When you are at the point where you need to provide input to complete the process, move the mouse cursor over the image of the setup window. After the mouse pointer changes to a small dot, click anywhere in the virtual machine window. This action "captures" the mouse so that keyboard and mouse input is sent to the virtual machine. To return the input to the physical computer, press Ctrl-Alt-Left arrow and then move the mouse pointer outside of the virtual machine window.  After the operating system is set up, you are ready to install the integration services. From the Action menu of Virtual Machine Connection, click Insert Integration Services Setup Disk. If Autorun does not start the installation automatically, you can start it manually. From a command prompt, type: %windir%\support\amd64\setup.exe.

After you have completed the setup and integration services are installed, you can proceed to test the virtual machine by customizing it to suit your testing goals. For example, you can view or modify the virtual hardware that is configured for the virtual machine. From the Virtual Machines pane, right-click the name of the virtual machine you created in step 3 and click Settings. From the Settings window, click the name of the hardware to view or change it. In our case, we will use the same operation (Step 2) create 3 VM’s of Linux Debian or Ubuntu virtual servers with 1G ram and 30gb HDD for each of them and attaché to them real NIC,s for them inside of our host server (bridged) mode and install Linux OS’s from ISO’s .
