If you want to know how I used task scheduler to run the AOVPN VPN_Profile.ps1 script then read this post.

I am in the middle of a migration project from Direct Access to Microsoft Always on VPN and so far it’s going really well. Both VPN solutions are running side-by-side until I complete the user migration.

In my early days of testing though, I was working from home and wanted to test all of the tweaks and fine-tune adjustments to my VPN_Profile.ps1 script without having to deploy from Configuration Manager each time. (Some of the tweaks I was testing included adding routing, configuring NPS failover and certificate filtering and these will become blog posts in their own right soon.)

Non-Admin account? No Problem.

My test user account did not have any local or domain administrator privileges and I needed a method of quickly redeploying the tweaked VPN_Profile in order to test the new configuration.

I did this through a scheduled task - it’s easy enough to do and this is how I achieved it:

Step 1: Generate the VPN_Profile.ps1 Script

Follow the methods in the Microsoft documentation to generate your VPN_Profile.ps1 script.

Step 2: Obtain the SID for Your Test User Account

Obtain the SID for your test user. To do this, in a PowerShell prompt, run the following command:

Get-ADUser fred.bloggs

Replacing fred.bloggs with the name of your test user account.

Make a note of the SID from the PowerShell output:

Step 3: Edit the VPN_Profile.ps1 Script

Open the VPN_Profile.ps1 script in the ISE of your choice.

In the first ‘Try \ Catch’ block in the script, edit the lines as shown in my screenshot below.

Essentially the following adjustments need to be made:

  • Set the variable $Username to domain\Username eg Mydomain\fred.bloggs (Line 67 in my screenshot) This user name should be your non-privileged test account user.
  • Comment out (by placing # in front of the line) the lines that start with $objuser and $sid (Lines 68 and 69 in my screenshot)
  • Set the variable $SidValue to the SID you obtained from step 2 (Line 70 in my screenshot)
  • Save the script

Step 4: Create a Scheduled Task

  1. Whilst logged in as your test user account, open Task Scheduler using an account with local admin rights:

  2. Right-Click the top node and select Create task…:

  3. Give your task a name, in this example it’s called AOVPN Testing and then click the Change User or Group… button:

  4. The Select User or Group dialog box is displayed:

  5. Type SYSTEM and then click the Check Names button:

  6. Ensure that SYSTEM becomes underlined, then click the OK button:

  7. Back on the General tab, ensure that you tick Run with highest privileges:

  8. Select the Actions tab and then click the New… button:

  9. Type the following in the Program/script text field:

    powershell.exe -executionpolicy bypass -file c:\path\to\your\vpn_deploy.ps1

  10. Click the Yes button when prompted about the arguments:

  11. Check that you have not made any typos, then click the OK button:

  12. To run the task, simply right-click it in the list of tasks and choose Run:

Anytime you make a new change to the VPN_Profile.ps1 script, delete the existing VPN connection settings, launch an elevated Task Scheduler and run the scheduled task again.
