LAPS Winform

*UPDATE*

I have created the *final* iteration of this WPF form which can be found here

*UPDATE*

I didn’t like having to remote desktop into my domain controller and couldn’t figure out if there was a LAPS tool included in RSAT tools so I decided just to make my own and to add some extra features.

I wanted the GUI to look pretty much identity to the actual LAPS GUI. You can see the difference below:

You might be able to see that I  changed the “Set” button to say “Set and Update”. This was because I wanted the form to also attempt to update the group policy settings on the computer so that it would get a new password a lot quicker than the original GUI.

There’s not much else I can say, I will leave the entire script below for you to copy and paste. You will need to add the domain controller for your environment in the $domaincontroller variable at the top of the script. I have converted this to an EXE and run whenever I need it, never skips a beat. Let me know how you get on with it. Enjoy!

Server Reboot Script

Running a little low on content this last few months, plus I’ve been busy with other work stuff.

I had the requirement to create a PowerShell script that would get the uptime of a server and then decide whether or not the server needed rebooting.

I also wanted the script to randomize the reboot of the servers, that way if there are multiple servers that need rebooting at once, they don’t cause a power spike or resource issues on the hosts. I did this by creating a random number between 1 and 5 and then if the number equals 5, the server is rebooted. If not then the server isn’t rebooted.

This is the script that I ended up with and what is currently being tested:

$loglocation = "C:\scripts\reboot\log"
$dateforfile = Get-Date

#GETS UPTIME IN DAYS
$lastbootuptime = Get-WmiObject win32_operatingsystem
$uptime = (Get-Date) - ($lastbootuptime.converttodatetime($lastbootuptime.lastbootuptime))
$uptimeindays = $uptime.days

#GETS RANDOM NUMBER
$randomnumber = Get-Random -Minimum 1 -Maximum 6

if ($uptimeindays -ge "14"){

 Add-Content -Path "$loglocation\$env:COMPUTERNAME.txt" -Value @"
=====================================================================================
Server restarted at:
$dateforfile
This was an immediate shutdown as the server had been up for $uptimeindays days
"@

 Restart-Computer -Force

}elseif ($uptimeindays -lt "14" -and $uptimeindays -ge "7"){

    if ($randomnumber -eq "5"){

        Add-Content -Path "$loglocation\$env:COMPUTERNAME.txt" -Value @"
=====================================================================================
Server restarted at :
$dateforfile
This was a random restart as uptime was only $uptimeindays days
"@
        Restart-Computer -Force
    }else{

        Add-Content -Path "$loglocation\$env:COMPUTERNAME.txt" -Value @"
=====================================================================================
Server NOT restarted
$dateforfile
This was not randomly restarted. Uptime is currently $uptimeindays days. Random number was $randomnumber
"@
    }
}else{

Add-Content -Path "loglocation\$env:COMPUTERNAME.txt" -Value @"
=====================================================================================
No restart required
$dateforfile
No restart required since uptime is only $uptimeindays days
"@
}

The first time I created this script and set it up as a scheduled task, nothing happened. Turns out that I needed the -Force parameter in order for the server to be rebooted.

This will later be used in a group policy without the log creating as that is only necessary in the testing stage.

Enjoy!

 

Creating a Logon Script To Cleanup User Directories

In this post, I’ll discuss how I created a PowerShell script that runs when a user logs out of a terminal server and cleans up a directory in their home folder that was filling up with space due to application crashes.

This is the script I created:

$username = $ENV:USERPROFILENAME

$testpath = Test-Path -Path "$username\AppData\Local\Microsoft\Windows\ApplicationFolder"

if ($testpath -eq $true){

 $items = Get-ChildItem - Path "$username\AppData\Local\Microsoft\Windows\ApplicationFolder"

 foreach($i in $items){

  Remove-Item -Path "$username\AppData\Local\Microsoft\Windows\ApplicationFolder\$i" -Recurse -Confirm:$FALSE

 }

}else{}

This code will get the users profile root path and then check if the application folder exists, if it doesn’t then the script ends. If it does exist, the script will cycle through each entry and remove it.

The -Confirm:$FALSE parameter was added because the script kept asking for confirmation when deleting each item. This stops this behaviors and deletes each item without a confirmation prompt.

Now that I have the script and it is working as expected, I create a local group policy that will use:

Name – “powershell.exe”

Parameters – “-F “C:\path\to\file.ps1”

You can see this in the screenshot below:

Logoff script group policy

 

This group policy was added under:

User Configuration – Windows Settings – Scripts (Logon/Logoff) – Logoff

Hopefully you can replicate what I have done and don’t experience any issue. Note that you might need to change the script execution policy on the machine before this works properly. Just something to keep in mind if the group policy isn’t working. Enjoy!
