How to read task sequence variables in a run state


For those times when you need to find out what a variable is set to while running a task sequence, you can run a simple script along with the variable name that you would like to check the value for. As long as the task sequence environment is available and the variable’s value is set to something other blank, it should return the value.

Code Sample

Dim sTSVar, sParameters, oTSEnv, Wsh
Set oTSEnv = CreateObject("Microsoft.SMS.TSEnvironment")
Set Wsh = CreateObject("Wscript.Shell")


Sub Main()
    On Error Resume Next

    If trim(Wscript.Arguments.Item(0)) <> "" Then
        DisplayVariables Wscript.Arguments.Item(0)
        Wscript.echo "No TS variables were passed for the script-" & Wscript.ScriptFullName
    End If
    If Err.number <> 0 then
        Wscript.echo "Error Writing the variable." & Err.Description
    End If
End Sub

Sub DisplayVariables(sParameters)
    Wscript.Echo oTSEnv(sParameters)

End Sub

Runtime Example

Let’s say you named your script readtsvar.vbs. While the task sequence was running you could hit F8 to open a command window and simple run the following:

cscript readtsvar.vbs OSDComputerName

This would return whatever the computer name variable is currently set to.
