Installing applications and packages dynamically during OSD

I wrote a post way back where I used a Powershell script to query AD group description for Applications to install dynamically during OS deployment in Configuration Manager. There was a couple of comments and recently a request to extend that script to also install packages dynamically during OS Deployment. The old post can be read here:

So here it is as promised, this script will install both applications and packages/programs during OS deployment dynamically.

It will read the description of AD groups and match it using a Prefix and Suffix to identify groups used for Applications / Packages. In the Description field for AD groups used for applications we add the application name and for packages we the packageID and program to run like shown below.

To use it:

  1. Save the script below and edit the following lines so it matches the environment it is run in
    $Prefix = “A.”
    $Suffix = “.i”
    $SiteCode = “060”
  2. Create a package with the script so we can run it in a Task Sequence
  3. Add the script to the Task Sequence using the run Powershell script command
  4. Add an Install Application Step using these settings.

    With the following condition so it is skipped if the are no applications to install
  5. Add an Install Packages Step using these settings.

    With the following condition so it is skipped if there are no packages to install


The script:

# Written by Johan Schrewelius / Jörgen Nilsson
# Version 1.1
# Added fallback to _SMSTSMAchineName if OSDComputerName is missing
# Thanks to Daniel Marklund for testing and adding features (Nested groups)!
# Version 1.2
# Update 2/12/2017: Added support for PackageID:Program in description attribute – Limitation: Application name must not start with SiteCode

$Prefix = “A.”
$Suffix = “.i”
$SiteCode = “060”

$tsenv = New-Object -COMObject Microsoft.SMS.TSEnvironment

$CmpName = $tsenv.Value(“OSDComputerName”)
if(!$CmpName) { $CmpName = $tsenv.Value(“_SMSTSMachineName”) }

$ADObjectDN = ([ADSISEARCHER]”samaccountname=$($CmpName)`$”).Findone().Properties.distinguishedname
$AllGroups =([ADSISEARCHER]”member:1.2.840.113556.1.4.1941:=$ADObjectDN”).FindAll()

$DescList = $AllGroups.Path `
| Where { ($_ -replace ‘^LDAP://CN=([^,]+).+$’,’$1′).StartsWith($Prefix) -and ($_ -replace ‘^LDAP://CN=([^,]+).+$’,’$1′).EndsWith($Suffix) } `
| Foreach { ([ADSI]”$_”).Description }

$AppCount = 1
$PkgCount = 1

$DescList | Where { !$_.StartsWith($SiteCode) } | Foreach { $tsenv.Value(“COALESCEDAPPS” + ($AppCount++).ToString(“00”)) = “$_” }
$DescList | Where { $_.StartsWith($SiteCode) } | Foreach { $tsenv.Value(“PACKAGES” + ($PkgCount++).ToString(“000”)) = “$_” }

That is it.
