  1. Hi Bezalel, I would agree that the procedure is more complicated than need be there are a couple of reasons for this though: 1) Credentials are not embedded in the build because we have a policy.. no domain credentials are to be stored in plain text.. anywhere.. (I added provision for the script to have credentials embedded in it however, and this has been used when rebuilding large numbers of machines outside of hours.. kinda bending policy here..) 2) Management doesn't want to fork out for storage for roaming profiles.. (C'mon.. What the hell?!!!) 3) The script is designed to request credentials/computer name by default (machines need to be labeled/tagged at build/rebuild time, so can't really be automated in a sane fashion..) 4) Drivers.. blah.. I had 3 days to knock the whole thing together.. I would have liked to build a database for PCI ID's/drivers.. but 3 days wasn't gonna cut it! 5) WSUS.. it is handled by a GPO, but do you really want to leave it up to users to keep installing updates for the next few days? The script just forces installation of ALL updates on the spot Aside from that - I think what I've put together _should_ be easier to maintain (eg. adding drivers) for whoever replaces me.. this place is run on a shoe-string, I doubt they will get someone who has the know-how to build up driver inf's for.. interesting hardware.. Whereas this process will allow them to basically extract drivers from *.zip/*.exe etc.. dump them in a folder and give it a whirl.. if something doesn't install on it's own, add the driver installer executable to the respective post_install batch file with a silent switch.. and be done with it.. Oh, on another note - do you get much trouble with multiple drivers for the same PCI ID? or are you fixing inf's by hand on conflict? Cheers, Mike
  2. I just thought I would document what I have done for a "one image to rule them all" build here - in case the information is useful to other people.. Outline of what this does: 1) Basic installation on any hardware platform (only NIC+Mass storage are included) 2) Detect machine type (desktop/laptop) and model (bios model) 3) "Fix" computer accounts in A/D (explained later on..) 4) Join domain, download drivers for model and install 5) Install software (configurable per machine) 6) Copies user profiles (if found for that computer) 7) Updates via WSUS/Windows update etc.. Why in gods name does it do this "stuff"?! I inherited this network in a rather sad state: * No standard hardware (a quick scan of the network yeilds ~60 different configurations) * No standard naming convention (Bob1, Warehouse2, Lenovo-123456) * Slow (aging hardware, domain migration, patch bloat..) * Software on many machines is non-standard (eg. alot of the workstations have one-off pieces of software installed) Now for the fun part.. <Image Path>\i386\Templates\image.sif [Unattended] UnattendMode=FullUnattended OemPreinstall=Yes TargetPath=\WINDOWS NtUpgrade=No OverwriteOemFilesOnUpgrade=No OemSkipEula=Yes DUDisable=Yes DriverSigningPolicy=Ignore ExtendOemPartition=1 ForceHALDetection=Yes Repartition=Yes OemSkipWelcome=1 UnattendSwitch=Yes OemPnPDriversPath = Drivers\Nic [GuiUnattended] AdminPassword=<password here> EncryptedAdminPassword=Yes OEMSkipRegional=1 TimeZone=290 OemSkipWelcome=1 [Identification] JoinWorkgroup=RIS_BUILD [GuiRunOnce] Command0=%SYSTEMDRIVE%\INSTALL\post_install.cmd Only relavent code is included for brevity.. so a very basic sif..

If a valid mac address is found.. get further configuration from a folder on the WDS server (name, software to install) Create a cmd file in the all users startup folder, for subsequent reboots.. Show the "prompter", which requests a username/password/computer name, "fixes" computer accounts, saves the username/password in the registry for autologon, and reboots.. CHECK_DOMAIN Try and connect to the domain controllers netlogon share, post a message if it fails.. INSTALL_DRIVERS Calls the get_mode_drivers.vbs script, which determines the computer model, then looks on the WDS server for drivers for that model, then copies them locally. This script has a "failsafe", which copies everything from driverpacks.net.. Use DPINST.EXE to install PnP drivers Note: some hardware configurations don't have drivers that install cleanly (eg. nvidia graphics cards), so the driver_post_install.cmd can be used to run driver executables to "fix" things like that.. SET_RESOLUTION Some software we use will not install if the resolution/colour depth are set too a low level.. Uses QRes to (try) change the resolution INSTALL_SOFTWARE Ug.. not gonna go into any detail on my software installation scripts here (happy to answer questions though..), needless to say, I have written a set of scripts that behave somewhat similar to apt-get/yum etc.. (eg. software is installed as a "package", packages can have dependcies etc..) COPY_USER_PROFILES Does what it says, profile backup script included below to show how it works.. WSUS_UPDATES calls the wsus_update.vbs script, then reboots.. 3 times for sanity CLEANUP Remove autologon information, remove the script "bootstrapper" from the all users profile, then self destruct Phew! hope that high level description is enough for you guys.. feel free to ask questions..

Computer Model: ABC123 Search order: ..\A ..\AB ..\ABC ..etc In other words, match as close as possible to the model name, this way, computers with different revisions (ABCv1, ABCv2, ABCv3) can be grouped into ABC! wsus_update.vbs is not included here - it was poached from: http://www.vbshf.com/?p=13 That's all for now guys - feel free to ask any questions you like!
