(Powershell script) Move Computer to Windows 8 OU based on prior OU set in OSD variable in OSD

Question

We have Windows 7 and Windows 8 machines that get configured through SCCM 2012 OSD. In my task sequence I have the computer joined to an OU based on the drop down selection. However I cannot write something into the javascript to put a computer into the
sub ou labeled windows 8. I would like to write a powershell script that will put the computer into the sub OU based on what was selected earlier.
Example: Computer is joined to Sales OU in our organization. There is a sub OU called Windows 8 under the Sales. If Sales is selected then it should join that subOU Windows 8.  Has anyone accomplished this task before? How would I write this? I have enclosed
a photo of what my OSD looks like. Very simple. This hta exports the OSDDomainOU variable out and the apply network settings task sequence grabs it and joins it to the selected OU.

Answer 1

I would use a switch statement and it would be something like this
function Set-OSDVariable
Param (
[string]$OSDVariable,
[string]$OSDVarValue
$tsenv = New-Object -ComObject Microsoft.SMS.TSEnvironment
$tsenv.Value($OSDVariable) = $OSDVarValue
function Get-OSDVariable
Param (
[string]$OSDGetVar
$tsenv = New-Object -ComObject Microsoft.SMS.TSEnvironment
$tstOSDVar = $tsenv.Value("$OSDGetVar")
return $tstOSDVar
$osddomainou = Get-OSDvariable -OSDGetVar "osddomainouname"
switch($osddomainou)
"external" { Set-OSDVariable -OSDVariable "osdomainnameou" -OSDVarValue "win8 external ou" }
The function included in the script above sets OSD Variables and I call it on the switch statement. Follow that format for the rest of the possible OU's. I've also included a function to get the variable too.
