MDT – Use MDT cross domain / workgroups

Published / by Rens Hollanders / 2 Comments on MDT – Use MDT cross domain / workgroups

Hi there,

Just a short post of something I had to deal with very recently, an MDT environment that is cross domain / workgroup connected.

Basically I had two challenges:

  1. Connecting to different shares based on DefaultGateway
  2. Connecting to shares in a domain and in a workgroup

The following example of the bootstrap.ini, does just that:

As you can see here, I use the DefaultGateway section to process from which location the machine is going to be deployed, to choose the designated deploymentshare for this particular location.

Next thing, is making sure the authentication of the shares is going smoothly. My first try was using the “LocationServer.xml“, this seemed to solve my problem of having multiple shares. Unfortunately, when you use LocationServer.xml it will destroy your authentication settings, since they are not parsed through while processing the xml file. Leaving you with a question to authenticate (again!) with the target share.

/rant the not parsing of the credentials while using LocationServer.xml is something that goes back since 2010. A thread on social.technet answered by Keith Garner,ย reports that a bug was filed, butย it did never make it to any new release of MDT ๐Ÿ™

So how did I get around this, by putting all the common denominators in the default section, and all the anomalies in the DefaultGateway subsection. Giving me the opportunity to use the same account, but use a different UserDomain. This means you can use the same account (a domain account for the machines in the domain, and a local account for the machine in the workgroup)

Also since the deploymentshare outside the domain, cannot be resolved by DNS, you’ll need to map this share based on an ip address.

Now doing the same thing for the CustomSettings.ini, gives me to opportunity, to put logfiles for each machine on the same location where it has been deployed.

Happy deploying ๐Ÿ™‚

Cheers! Rens

 

MDT2013 – Powershell ‘BESERK’ mode, configure everything with Powershell!!!

Published / by Rens Hollanders / 5 Comments on MDT2013 – Powershell ‘BESERK’ mode, configure everything with Powershell!!!

Very recently, deploymentreseach’ Johan Arwidmark, blogged about configuring your DeploymentShare properties (which are saved in .\Control\Settings.xml) with Powershell.

Some time ago I started working on some Powershell scripts myself, mostly oriented on configuring the bootstrap.ini and customsettings.ini, and creating some folders within the MDT Workbench.

While I never had gotten the time and energy to finish it, Johan’s blog basically pushed me over the edge, and then it happened… I went BESERK /cannot compute ๐Ÿ˜›

beserk

The result you can find in the following script which not only configures your deployment share properties, but also configures:

  • Bootstrap.ini
  • CustomSettings.ini
  • Modifies “.\Scripts\Litetouch.wsf” to use the _SMSTSPackageName variable
  • Configure DeploymentShare Properties
  • Creates a folderstructure within MDT
  • Creates selection profiles within MDT

The script! Updated @ 2014-03-20

Basically this script can be divided into five pieces:

1. Constants

The constants that I have declared are the variables that represent the value that is shown, by modifying these values, you can customize and personalize this script for your own purposes. This script is primarily intended for new to be configured deployment environments, so keep in mind that using this script on existing environments will overwrite all content within the bootstrap.ini and customsettings.ini!

2. Configuring Bootstrap.ini and Customsettings.ini

Basically I use a multiline string for both my Bootstrap.ini and CustomSettings.ini and within that line of code, on certain places I call my variables. This way the variables will be used for input, instead of having to change a server name every single time on every single row of code.

3. Configuring the DeploymentShare properties

This part we already know from Johan / deploymentreseach, however I’ve took the liberty to customize it to my wishes, and fully write out all the available settings in .\Control\Settings.xml

4. Configure a logical folderstructure within the MDT Workbench

This part is quite new, I now know again thanks to Johan and Roger the Young a PSDrive can be browsed from a powershell command prompt, just type: dir ds001: and you can actually see and browse the MDT Workbench ‘folder structure’.

figure 1.1: Browse PSdrive

psdrive

If you want to browse any further, just type dir DS001:\Applications or “DS001:\Operating Systems” (note that if you use spaces in your folders, you need to use quotes “”)

5. Configure selection profiles for Driver and Packages selection

The last thing I wanted to do is configure pre-configured selection profiles which can be uses for injecting certain drivers, targeting packages, creating media etc.

What has changed since 2014-03-20

The script needed some simplification to avoid having to enter the same values at different places. Also now the script creates an entire deployment share for you. So now there is no need to create an deploymentshare with MDT before executing this script. Lastly the ZTIDiskpart.wsf will be modified to calculate with binary metrics. So a 100 Gb disk partition specified will actually end up as an 100 Gb disk partition instead of 98,7 Gb.

Closing

Is this the right way to do it, I have no clue, what I do know is that I never want to configure a deploymentshare manually ever again, so this script definitely helps me. Also, adjusting the values of the constants declared is a fraction of the effort I have to put in vs. going through “Create folder” wizards for the 50th time.

Special thanks go out to scripting wizard Roger the Young a.k.a. “DrillSergeant” and Johan Arwidmark, for giving me renewed inspiration to continue to develop this script in what it has become.

ps I. forgive my powershell language, using words as constants, variables, properties and values, are perhaps not used in the correct way! -im still trying ๐Ÿ™‚

ps II. also I can imagine this script can be simplified drastically, and I don’t mind if you do, as long as you share it back with me, like I shared it here with you ๐Ÿ˜€ Or as the Germans say: “wiedersehen macht freude”

MDT 2012 Settings for fully automated LTI deployment, Part I: Bootstrap.ini

Published / by Rens Hollanders / 16 Comments on MDT 2012 Settings for fully automated LTI deployment, Part I: Bootstrap.ini

So based on some blogs I’ve read and a recent project I have worked on to realize a fully automated Operating System Build, I wanted to share my settings just to clarify which settings need to be present within the bootstrap.ini and the customsettings.ini.

Part I: Bootstrap.ini

First of all, there is the bootstrap.ini. Customizing the bootstrap.ini affects all the settings which a machine will be booted with. In my case it was necessary to provide a static IP configuration because the server back-end where I had a test virtual machine to my disposal had no active DHCP running, therefore it is necessary to specify the IP configuration for one or more machines.

If we want to do this for one machine, we need to have a unique identifier which the settings can be applied to, in this case it would be the MAC Address of the virtual machine which in our case will not change automatically (VMware HyperVisor, on Hyper-V you need to specify a static IP). Therefore we set our Priority to MAC Addres 1st, and then the Default configuration options 2nd because we want those options to be applied to all clients.

[Settings]
Priority = MACADDRESS, Default

Then it is time to configure our network adapter, in case of a virtual machine it is likely that we have only one network adapter present. Therefore we need to specify the MAC Address of that adapter between the “[ ]”.

Next we specify the number of available network adapters, in case there is one we set our “OSDAdapterCount” to 1.
If there is no DHCP available we set the OSDAdapter0EnableDHCP to FALSE to make sure that when the machine boots into WinPE no instruction will be executed to request an dynamic provided IP address.

By specifying the following settings we provide our adapter configuration as we would normally do in Windows also when we want to specify a static IP address:

OSDAdapter0IPAddressList=Enter the machine’s IP address here
OSDAdapter0SubnetMask=Provide the correct subnet here
OSDAdapter0Gateways=Provide the gateway address
OSDAdapter0DNSServerList=Provide multiple DNS servers by using “,”
OSDAdapter0DNSSuffix=Provide the DNS Suffix so that machines that are not domain joined can still communicate with domain joined servers and computers

[00:00:00:00:00]
OSDAdapterCount=1
OSDAdapter0EnableDHCP=FALSE
OSDAdapter0IPAddressList=192.168.1.45
OSDAdapter0SubnetMask=255.255.255.0
OSDAdapter0Gateways=192.168.1.1
OSDAdapter0DNSServerList=192.168.1.11,192.168.1.12
OSDAdapter0DNSSuffix=contoso.local

*Note: working with multiple network adapters needs further explaination and luckely another MDT Exprert “Andrew Barnes a.k.a. Scriptimus Prime” has written a nice blog about that:ย MDT 2012: Automating Network Interface Configuration

Now we have specified our IP configuration based on MAC Address we can specify our Default settings which will be applied to al machines who will connect to the MDT deploymentshare.

Obviously we need a connection to our deploymentshare which is located on the network, with the property “DeployRoot” we specify the network location where the share is located.

By specifying “SkipBDDWelcome” we skip the screen where we can chose for running a new deployment, so that the wizard will automatically advance to the customized MDT wizard for deploying machines.

It is also possible to specify the keyboard layout allready, this is especially handy when you need to authenticate to your deployment share by password with keyboard symbols and characters.

[Default]
DeployRoot=\\servername.contoso.local\deploymentshare$
SkipBDDWelcome=YES
KeyboardLocalePE=nl-US

Then off-course it is time to configure our user account which is used to connect to the deploymentshare. No additional rights other then Read, List and Execute are necessary so an specified service account with ‘Domain User’ rights will do the trick if you set your NTFS and Sharing permissions right on the deploymentshare!

UserID=mdt_sa-account
UserPassword=P@55w0rd
UserDomain=contoso.local

So far my first part of explaining how to realize a fully automated deployment.
