Back to Basics – Restoring the SMSDP Variable

Once upon a time, in a ConfigMgr environment far, far away. There was a variable named SMSDP… 🙂

There are times when its useful to figure out what DP you are currently using, and back in ConfigMgr 2007, when integrated with MDT, there was a variable for that: The SMSDP variable .

Here is a script for ConfigMgr Current Branch that sets that variable:

# Script for setting the SMSDP variable in ConfigMgr Current Branch

# Create TS environment object
$TSEnv = New-Object -ComObject Microsoft.SMS.TSEnvironment

# Get the boot image package ID
$BootImagePackageID = $TSEnv.Value("_SMSTSBootMediaPackageID")

# Get DP from _SMSTSHTTP variable for boot image package
$SMSDPUri = [System.Uri]"$($TSEnv.Value("_SMSTSHTTP$BootImagePackageID"))"
$SMSDP = $SMSDPUri.Host

# Set SMSDP Variable 
$TSEnv.Value("SMSDP") = $SMSDP

Just paste the above script in a Run PowerShell Script action in the task sequence, and you're all set.

To verify the variable in WinPE, start PowerShell, and type in the following:

$TSEnv = New-Object -ComObject Microsoft.SMS.TSEnvironment
$TSEnv.Value("SMSDP")
