2 2 RIS Overview Remote OS Installation Overview Remote Install Server Components Remote Install Client Components How the Remote OS Installation Process Works RIS Server and Client Requirements Network Cards Supported by RIS Boot Disk

3 3 Remote OS Installation Overview

4 4 Remote Install Server Components Boot Information Negotiation Layer (BINL) Trivial File Transfer Protocol Daemon (TFTPD) Single Instance Store (SIS)

5 5 Boot Information Negotiation Layer (BINL) Added during the RIS installation process and provides overall management of the RIS environment Responsible for answering client computer network service requests Responsible for querying Active Directory on behalf of the client computer Responsible for ensuring that the correct policy and configuration settings are applied to the client computer during the OS installation Ensures that the client is passed the correct files Makes sure the correct RIS server services a prestaged client Creates the client computer account object within Active Directory if the client computer has not been prestaged

6 6 Trivial File Transfer Protocol Daemon (TFTPD) Server-side TFTP service Responsible for hosting specific file download requests made by the client computer Used to download the CIW and all client dialog boxes contained within the CIW for a given session

7 7 Single Instance Store (SIS) Responsible for reducing disk space requirements on the volumes used for storing RIS installation images. When RIS is installed as an optional component, the administrator is prompted for a drive and directory where to install RIS. Attaches itself to the RIS volume and looks for any duplicate files that are placed on that volume. Creates a link to any duplicates found, thus reducing the disk space required.

8 8 Types of Remote Boot- Enabled Client Computers Computers with PXE DHCP-based remote boot ROMS Computers with network cards supported by the RIS boot disk

9 9 PXE Remote Boot Technology Remote OS Installation uses the PXE remote boot technology to initiate the installation of an OS from a remote source to a client hard disk. The remote source, a server that supports RIS, provides the network equivalent of a CD-based installation of Windows 2000 Professional or a preconfigured RIPrep desktop image. Windows 2000 Professional OS is currently the only installation option supported by RIS. Once images have been posted on the RIS server(s), end users equipped with PXE-based computers can request to install those images from any available RIS server on the network. Users can install the OS without administrator assistance, which saves both time and expense normally associated with OS installations.

10 10 CD-Based Installation Similar to setting up a workstation directly from the Windows 2000 Professional CD-ROM Differs from CD-ROM setup insofar as the source files reside across the network on available RIS servers

11 11 RIPrep Image Format Allows a network administrator to clone a standard corporate desktop configuration. After installing and configuring Windows 2000 Professional, its services, and any standard applications on the computer, the administrator runs a wizard that prepares the installation image and replicates it to an available RIS server for installation on other clients.

12 12 How the PXE Remote Boot Technology Works PXE is a new form of remote boot technology. PXE enables companies to use their existing TCP/IP network infrastructure with DHCP to discover RIS servers on the network. Net PC/PC98-compliant systems can take advantage of the remote boot technology included in the Windows 2000 OS.

13 13 PXE Remote Boot ROM Boot Process

14 14 The RIS Boot Disk Provided by Windows 2000 for computers that do not contain a PXE-based remote boot ROM so that a remote boot disk can be created for use with RIS Used with a variety of PCI-based NICs Eliminates the need to retrofit existing client computers with new NICs to take advantage of the Remote OS Installation feature Simulates the PXE remote boot sequence and supports frequently used NICs

15 15 RIS Architecture

16 16 How the Remote OS Installation Process Works The process is the same for both the PXE remote boot ROM and the RIS boot disk boot processes. The process of contacting an RIS server and selecting an OS image is accomplished in a few steps. The process is simple from an end user perspective. An administrator can guide the user through a successful OS installation by predetermining the installation options available. An administrator can also restrict the OS image(s) available to a user, thus ensuring the correct OS installation type is offered to the user for a successful installation.

18 18 CIW Installation Options

19 19 RIS Server Hardware Requirements Pentium or Pentium II 166 MHz; 200 MHz or faster processor recommended 64 MB of RAM; 96 to 128 MB if additional services such as Active Directory, DHCP, and DNS are installed 2 GB minimum hard disk or partition dedicated to the RIS directory tree; RIS requires a significant amount of disk space 10 or 100 mbps NIC; 100 mbps preferred

20 20 RIS Server Software Requirements DNS DHCP Active Directory

21 21 RIS Client Hardware Requirements Pentium 166 MHz or faster processor Net PC client computer 32 MB RAM minimum; 64 MB recommended 800 MB hard disk drive Supported PCI Plug and Play NIC Optional: PXE-based remote boot ROM version. 99c or later

25 25 Tasks to Configure RIS Authorize RIS servers Set RIS server properties Set RIS client installation options Set RIPrep image permissions

26 26 Authorizing RIS Servers Specifying the RIS servers that are allowed to run on the network can prevent unauthorized RIS servers, ensuring that only RIS servers authorized by administrators can service clients. Unauthorized RIS servers will be automatically shut down. An RIS server must be authorized before it can service client computers.

31 31 Setting RIS Client Installation Options Enables an administrator to control the options presented to different groups of users during the CIW. Four options can appear on the CIW: Automatic Setup, Custom Setup, Restart A Previous Setup Attempt, and Maintenance And Troubleshooting.

32 32 Restart A Previous Setup Attempt Provided in case the installation of the OS fails for any reason Enables administrators to customize the CIW to ask a series of questions about the specific OS being installed When restarting a failed OS setup attempt, the end user is not asked these questions again. Instead, Setup restarts the file copy operation and completes the OS installation.

33 33 Maintenance And Troubleshooting Provides access to third-party hardware and software vendor tools. Range from system BIOS flash updates and memory virus scanners to a wide range of computer diagnostic tools that check for hardware-related problems Available before installing and starting the OS on the client computer If the option to display the Maintenance And Troubleshooting menu is enabled, user access to individual tool images is controlled in the same way as OS options, by setting specific end user permissions on the individual answer file (.sif) for that tool.

35 35 Changes to RIS Policy Take effect only when the policy is propagated to the computer One of the following is done to initiate policy propagation: Type secedit /refreshpolicy user_policy at the command prompt, and then press Enter. Restart the computer. Wait for automatic policy propagation, which occurs at regular, configurable intervals; by default, every eight hours.

36 36 Setting RIPrep Image Permissions Enables administrators to guide users through the selection of the unattended OS installation appropriate for their role within the company. When an OS image is added to an RIS server, the image will be available to all users serviced by that RIS server.

37 37 Create an RIPrep Image Many organizations use disk imaging or cloning software to build and maintain standard desktops. Cloning software enables administrators to configure a client computer exactly how they want it, and then make a copy of that image for installation on client computers on the network. Remote OS Installation supports creation and installation of standard desktop images using RIPrep images. Before an RIPrep image can be created, the following tasks must be completed: Create the source computer Configure the workstation

38 38 Creating the Source Computer The Remote OS Installation feature is used to remotely install the base Windows 2000 Professional OS. Once the OS is installed, applications or application suites, including in-house LOB applications, are installed. The workstation is configured to adhere to company policies.

39 39 Configuring the Workstation When creating RIPrep images, understanding the relationship of user profiles, the changes made to an RIPrep source computer, and the desired result for users that log on to computers installed using the RIPrep image is important. Applications that carry the “Certified for Windows” logo properly separate user- and computer-specific configuration settings and data. Certified applications are also available to all users of systems later installed with the resulting RIPrep image. Non-Windows 2000–compliant applications may perform and/or rely on per-user configurations that are specific to the profile of the user actually installing the application prior to running RIPrep, rather than to all users of the system.

40 40 Configuring the Workstation (con’t) Applications that remain specific to that user may result in the application or configuration setting not being available or not functioning properly for users of computers installed with the RIPrep image. Some non-application configuration changes, such as the wallpaper specified for the user desktop, are by default applied only to the current user’s profile and will not be applied to users of systems installed with the RIPrep image. Any applications or configuration settings desired for use must be thoroughly tested. Some configuration settings can be copied directly from the profile where they were applied.

41 41 RIPrep Requirements The destination computer is not required to contain hardware identical to that of the source computer used to create the image. The destination computer’s disk capacity must be equal to or larger than that of the source computer. All copies of Microsoft software made or installed using RIS must be properly licensed. All copies of other software made or installed using RIS must be properly licensed.

42 42 RIPrep Limitations RIPrep currently supports replicating a single disk–single partition Windows 2000 Professional installation to an available RIS server. The OS and all applications must reside on the C partition prior to running the Remote Installation Preparation Wizard. The Remote Installation Preparation Wizard currently allows source image replication only to available RIS servers; source replication to alternate drives or media types is not supported. Replication of encrypted files is not supported. Changes made in the source computer’s registry before running the Remote Installation Preparation Wizard are not maintained in the installation image. Modifications to replicated installation images are not supported.

43 43 Installation Image Sources The Remote Installation Preparation Wizard is used to create an installation image of a client computer that was originally installed using a retail version of Windows 2000 Professional. RIPREP.SIF must be modified to include the PID number. The PID is a unique identification number specific to each copy of Windows 2000 Professional used to identify the OS installation and track the number of copies installed throughout an organization.

44 44 Including the PID in the RIPREP.SIF File Open the RIPREP.SIF file located at \RemoteInstall\Setup\applicable_language\Images \applicable_image_name\I386\Templates\RIPREP.SIF. Type ProductID = “xxxxx-xxx-xxxxxxx-xxxxx” into the [UserData] section of the RIPREP.SIF file. The PID for each client installation is randomly generated using the PID entered in the RIPREP.SIF file.

45 45 Create an RIS Boot Disk A boot disk must be created to support existing client computers that do not have a PXE-based remote boot-enabled ROM but that do have a supported network adapter. The RIS boot disk works like the PXE boot process: Turn on the computer, boot from the RIS boot disk, press F12 to initiate a network service boot, and the CIW is downloaded and starts. The rest of the RIS process is identical regardless of whether the client was booted using a PXE boot ROM or the RIS remote boot disk.

47 47 Verifying an RIS Configuration RIS provides the ability to check the integrity of the RIS-enabled server. The RIS configuration can be verified if the server is suspected of failing, if inconsistent behavior is present, or if an RIS volume needs to be restored from backup. The Check Server Wizard checks whether all of the settings, services, and configuration options are correctly set and functioning.

49 49 Managing RIS Client Computers Prestaging RIS client computers Finding RIS client computers

50 50 Prestaging RIS Client Computers The process of creating a valid client CAO within Active Directory. After RIS client computers are prestaged, the RIS servers can be configured to respond only to prestaged client computers. Ensures that only those client computers that have been prestaged as authorized users are allowed to install an OS from the RIS server. Saves time and money by reducing or eliminating the need to fully preinstall the computer. Enables administrators to define a specific computer name and optionally specify the RIS server to service the computer. This information is used to identify and route the client computers during the network service boot request. The appropriate access permissions must be set for users of the prestaged client computer.

54 54 Finding RIS Client Computers Active Directory can be searched for RIS client computer accounts by using their computer name or GUID. The Show Clients feature searches for all client computers that are prestaged for this RIS server. The search process can include the entire Active Directory structure or can be limited to a specific domain. The search process returns a list of the client computers and displays them by their computer name and GUID.

55 55 GUID for Client Computers Overview The manufacturer supplies the computer’s GUID. The GUID must be in the form {dddddddd-dddd-dddd-dddd- dddddddddddd}, where d is a hexadecimal text digit. Valid entries for the client GUID are restricted to the following: 0 1 2 3 4 5 6 7 8 9 a b c d e f – A B C D E F. Dashes are optional and spaces are ignored; brackets {} must be included.

59 59 Initiating Policy Propagation Type secedit /refreshpolicy machine_policy at the command prompt, and then press Enter. Restart the computer. Wait for automatic policy propagation, which occurs at regular, configurable intervals; by default, occurs every eight hours.

60 60 RIS Frequently Asked Questions and Troubleshooting Frequently Asked RIS Questions Troubleshooting RIS

61 61 Symptom: Command Settings Are Not Being Processed During the Unattended Installation Cause: When using the “OemPreinstall = yes” setting in an.sif file, the correct directory information is required Solution: Change the directory information to \RemoteInstall\Setup\applicable_language\Images \applicable_image_name\$oem$

62 62 Symptom: Language Choice Options Are Not Displayed During the CIW Session Cause: By default, RIS uses the WELCOME.OSC file to manage the client installation image choices. For multiple language installation image options, the default WELCOME.OSC file needs to be replaced with the MULTILND.OSC file. Solution: The CIW uses the WELCOME.OSC file located in the \RemoteInstall\OSChooser folder to manage client installation image choices. After WELCOME.OSC is removed and MULTILNG.OSC is renamed to WELCOME.OSC, the CIW will also offer a menu of multiple language choices to the user. The WELCOME.OSC file can be edited to create custom language options.

63 63 Symptom: The Client Computer Is Prestaged to an RIS Server But Is Being Serviced by a Different Server Cause: When a client computer is prestaged into a domain with multiple domain controllers, the replication delay of the CAO information can cause a client computer to be serviced by another RIS server Solution: Wait for the computer account information to be propagated during the next scheduled replication session or modify the replication frequency between the domain controllers

64 64 Symptom: Following the Restoration of a Backup of an RIS Volume, RIS No Longer Functions Properly Cause: Backup restored the volume without an SIS directory Solution: Verify the configuration of the RIS volume and then restore the volume again
