1. 21/10/2002W2K RIS - HEPix Fall 2002 Remote Installation Services Michel Jouvin LAL / IN2P3 Jouvin@lal.in2p3.fr

2. 21/10/2002W2K RIS - HEPix Fall 2002 What is RIS MS implementation of a PXE server to allow system installation through the net Advantage over older technologies –No need for a specific floppy : PXE client available in modern BIOS –Integration with AD allows control on who can install what on a specific machine –Based on imaging technologies –Several preconfigured images can coexist on the server

3. 21/10/2002W2K RIS - HEPix Fall 2002 RIS Server… Preferrably a DC but not mandatory –If not a DC, DHCP server must be registered (authorized) RIS Management done in RIS server properties in ‘ActiveDirectory Users and Computers’ tool DHCP –Address and bootfile discovered through DHCP Can be provided by different servers (normally) –Bootfile = Client Installation Wizzard (OS chooser) –Allow to restrict access to known (pre-staged) clients

4. 21/10/2002W2K RIS - HEPix Fall 2002 … RIS Server BINL : Bind Information Negociation Layer –TFTP server –Management of images –Discovery of NIC driver during Setup startup –AD interaction : computer account creation –Possible generation of computer names based on customizable template

5. 21/10/2002W2K RIS - HEPix Fall 2002 RIS Client BIOS based PXE client –No configuration needed – Generally through F12 –Often buggy : BIOS upgrade needed (Dell Latitude) –Generally requires address and bootfile in the same DHCP transaction (one DHCP server for both) Floppy based PXE client –Generic but limited list of supported (PCI only) NIC No miniPCI support : don’t work with laptops Generated with Rbfg.exe in REMINST\Admin\I386 –Accept address and bootfile from different DHCP servers –GUID based on MAC address (NIC) instead of computer

6. 21/10/2002W2K RIS - HEPix Fall 2002 Client Installation Wizzard… File booted through PXE (OS Chooser) –Authenticate the person doing the install Logged in event viewer –Ask configuration parameters (computer name…) –Select image to install –Launch installation (flat or Riprep images) –Default CIW require F12 REMINST\OSChooser\I386\Startrom.exe Use (rename) startrom.n12 to suppress F12

7. 21/10/2002W2K RIS - HEPix Fall 2002 … Client Installation Wizzard Form based interface –Forms described in OSCML (HTML 2.0) Forms files in REMINST\OSChooser Easy to customize –Parameters passed to installer through variables –Preconfigured set of parameters attached to each images several per image similar to unattended.txt options

8. 21/10/2002W2K RIS - HEPix Fall 2002 Images Location –Both under \REMINST\Setup\language –One directory per image –Image directory name can be changed Enumeration redone each time by OS Chooser 2 types of system image –Flat image : CD like distribution –Riprep image : copy of an installed and configured system (with applications)

9. 21/10/2002W2K RIS - HEPix Fall 2002 Flat Image Can install on every computer Run standard setup (pretty long) Added to RIS through RIS management tool –Can be done manually by copying the CD and building the Template subdirectory Flat image with the same system version/SP must exist for a Riprep image installation to start –Don’t integrate SP if used by Riprep image Generally restricted to administrators

10. 21/10/2002W2K RIS - HEPix Fall 2002 Riprep Images Differences from flat images –Includes deployment of applications –Deployment much faster than flat image (#20mn) –Target computer must have the same HAL type Built with Riprep.exe (similar to Sysprep) –Install and configure a system with application –Run Riprep from \\RIS_Server\REMINST\Admin\I386\\RIS_Server\REMINST\Admin\I386 –Riprep uses sysprep.inf as input Sysprep.inf (in \Sysprep folder) allows a subset of SIF options –Riprep reset registry on the Riprep computer

11. 21/10/2002W2K RIS - HEPix Fall 2002 Image Management SIF files –Describe installation options for an image Domain to join, computer name, drivers path… –Reside in I386\Template subdirectory of the image –File organised in section (like an INI file) –Several set of options per image Name presented to the user is defined in OSChooser section SIF ACLs –SIF access done with the user authenticated by CIW –ACLs can be placed on SIF files or Template subdir to restrict access to image (template) to some users

12. 21/10/2002W2K RIS - HEPix Fall 2002 Driver Addition (Flat Image) Create under I386 $OEM$\$1 subtree Create a subdirectory/subtree where to place drivers –Ex: Driver, or Driver\NIC, Driver\Video… Copy the drivers in the appropriate location In SIF file [unattended] section, add : OEMPreinstall = yes OemPnpDriversPath = DriverPath DriverPath is a semi-colon separated list –Drivers must reside in the listed directories, not subdirectories

13. 21/10/2002W2K RIS - HEPix Fall 2002 Driver Addition (Riprep Image) Must be done before running Riprep –Not necessary if flat image used is already configured On the reference computer, create a directory/tree Put the drivers in the appropriate location In Sysprep.inf file [unattended] section, add : OemPnpDriversPath = DriverPath Before running Riprep, be sure to deinstall all unknown devices (from Device Manager)

14. 21/10/2002W2K RIS - HEPix Fall 2002 Driver Addition (Miscellanous) New driver can be added to an existing images by copying them in the appropriate location –No need to rebuild the image If the NIC used by RIS client is not supported by standard drivers, the driver (and.INF) must also be added to the flat image I386 directory –Require restart of binlsvc service Reconstruct PNF file corresponding to the INF file (long) –Easier to add new driver than replace…

15. 21/10/2002W2K RIS - HEPix Fall 2002 Server Troubleshooting Standard RIS logs in event viewer (DHCP and BINL) : not very detailed/helpful Detailed BINL logs –Define (DWORD) value Debug to 1 in HKLM\System\CurrentControlSet\Services\Binlsvc\Par ameters –Logs are in %SYSTEMROOT%\Debug\binsvc.log Need to be copied (locked) and opened with Wordpad

16. 21/10/2002W2K RIS - HEPix Fall 2002 Installation Troubleshooting GUI Setup part –Log in setupapi.log in %SYSTEMROOT% –Default log level is non verbose Define (DWORD) value LogLevel to xFFFF in HKLM\Software\Microsoft\Windows\CurrentVer sion\Setup –For flat images, must be done by adding the value to hivesft.inf –For Riprep images, must be set on the computer used to build the image

17. 21/10/2002W2K RIS - HEPix Fall 2002 Current Problems/Restrictions New NIC integration –Difficult if older driver version exists (Intel Pro 100) –SP3 required on server but not enough… CIW assumes QWERTY DCHP restriction for BIOS based clients -Tested with Intel and 3COM agents Drivers path limited to 10 elements in SIF files Only one sytem disk (with one partition) -Target computer must have a disk equal or greater to source computer

18. 21/10/2002W2K RIS - HEPix Fall 2002 Documentation on RIS W2000 Server Deployment White Papers –W2000 Server Deployment Planning guide – Ch. 8 –Remote Operation System Installation –Technical Guide to Remote Installation Services –Step by Step guide to Remote OS Installation Lot of KB articles –Mainly for toubleshooting installation start problems –Keywords : RIS or PXE Machine or NIC vendors support sites –Ex : Intel
