Task Sequence Variables

Hi All,

I have created a task sequence with custom variables. I would like to carry over those variables to the OS Setup portion which actually the variables are not available any more.
What is the best way to go about it?

Do i have to export the variables in a file and re-import them in the OS set up ?

So to give some background i am building with DHCP however in the last step after the config manager client set up i would like to set up static ip addresses. Those ip addresses have been inputed on winPE during the task sequence start.

    Assuming this is the same question from Reddit, has this not been resolved by using the Microsoft.SMS.TSEnvironment COM object from within your PowerShell script to access the task sequence variables and their values?

    Hi @mmtechsupport ,

    Agree with Jason, we could export SCCM task sequence variables with PowerShell.

    Please refer to this article:

    Sorry, but no. I'm not at all saying to export or dump the variables.

    As noted, if this is the same as the Reddit thread, the problem is that you cannot directly access task sequence variables within a PowerShell script run during a task sequence as if they were PowerShell variables without using the Microsoft.SMS.TSEnvironment COM object.

    So i have now resolved it

    Thank you all for help

    I had to do 2 things.

    First - make the variables available to PowerShell.
    Second - do that inside the PowerShell script - NOT in a discreet TS step.

    Works fine!
