If you are having issues with some users having freeze issues and high response time in Citrix Director, this registry key might help you. It happens in conjunction with dedicated GPUs on notebooks. The key disabled GPU acceleration for Citrix Workspace App.

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICA Client\Graphics Engine] “HWacceleration”=dword:00000000

If you need to perform a packet capture under Windows without having to install Wireshark, here are some netsh commands:

netsh trace start capture=yes tracefile=c:\net.etl persistent=yes maxsize=4096 filemode=circular overwrite=yes report=no

When you are done with your capture do:

netsh trace stop

This will take some time.

You will see the files under C:\net.etl and net.cab

This quick script shows you if and where inheritance is deactivated. You can also set in the parameters how deep or how many levels inheritance is checked.

# Function to check inheritance up to the specified level
function Check-Inheritance {
    param (
        [string]$directoryPath,
        [int]$currentLevel,
        [int]$maxLevel
    )

    # Exit if current level exceeds max level
    if ($currentLevel -gt $maxLevel) {
        return
    }

    # Get the ACL of the directory
    $acl = Get-Acl -Path $directoryPath

    # Check if inheritance is disabled
    if ($acl.AreAccessRulesProtected) {
        Write-Output "$directoryPath - Inheritance is disabled"
    } else {
        #Write-Output "$directoryPath - Inheritance is enabled"
    }

    # Recursively check subdirectories if current level is less than max level
    if ($currentLevel -lt $maxLevel) {
        $subdirectories = Get-ChildItem -Path $directoryPath -Directory
        foreach ($subdir in $subdirectories) {
            Check-Inheritance -directoryPath $subdir.FullName -currentLevel ($currentLevel + 1) -maxLevel $maxLevel
        }
    }
}
# Function to check inheritance up to the specified level
function Check-Inheritance {
    param (
        [string]$directoryPath,
        [int]$currentLevel,
        [int]$maxLevel
    )

    # Exit if current level exceeds max level
    if ($currentLevel -gt $maxLevel) {
        return
    }

    # Get the ACL of the directory
    $acl = Get-Acl -Path $directoryPath

    # Check if inheritance is disabled
    if ($acl.AreAccessRulesProtected) {
        Write-Output "$directoryPath - Inheritance is disabled"
    } else {
        #Write-Output "$directoryPath - Inheritance is enabled"
    }

    # Recursively check subdirectories if current level is less than max level
    if ($currentLevel -lt $maxLevel) {
        $subdirectories = Get-ChildItem -Path $directoryPath -Directory
        foreach ($subdir in $subdirectories) {
            Check-Inheritance -directoryPath $subdir.FullName -currentLevel ($currentLevel + 1) -maxLevel $maxLevel
        }
    }
}

To execute the script:

Check-Inheritance -directoryPath $rootDirectory -currentLevel 1 -maxLevel 3 

As a follow up to my last article regarding Microsoft Teams NEW Addin missing in Outlook https://www.ajni.it/2024/03/microsoft-teams-lightweight-teams-meeting-addin-in-outlook-missing/, this script might help you if there are still some issues especially on Terminal Services/RDS 2019/2022.

This script registers Microsoft.Teams.Addin.Loader.dll as the current user, so it has to run at logon.

if (-not ($NewTeamsPackageVersion = (Get-AppxPackage -Name MSTeams).Version)) {
Write-Host "New Teams Package not found. Please install new Teams from https://aka.ms/GetTeams ."
exit 1
}
Write-Host "Found new Teams Version: $NewTeamsPackageVersion"

$TMAPath = "{0}\WINDOWSAPPS\MSTEAMS_{1}_X64__8WEKYB3D8BBWE\MICROSOFTTEAMSMEETINGADDININSTALLER.MSI" -f $env:programfiles,$NewTeamsPackageVersion
if (-not ($TMAVersion = (Get-AppLockerFileInformation -Path $TMAPath | Select-Object -ExpandProperty Publisher).BinaryVersion))
{
Write-Host "Teams Meeting Addin not found in $TMAPath."
exit 1
}
Write-Host "Found Teams Meeting Addin Version: $TMAVersion"

$TMAParam= '/s /n /i:user "C:\Program Files (x86)\Microsoft\TeamsMeetingAddin{0}\x86\Microsoft.Teams.AddinLoader.dll"' -f $TMAVersion
Start-Process "C:\windows\System32\regsvr32.exe" -ArgumentList $TMAParam

A follow-up on the last post here is another way to run msiexec through PowerShell.

For example, here is how you can install OCS inventory agent with some parameters. OCS is an open source inventarization system.

Start-Process -FilePath .\OCS-Windows-Agent-Setup-x64.exe -ArgumentList ‘/S /NOSPLASH /NOW /SERVER=https://inventory.ajni.it//ocsinventory /TAG=”a” /SSL=0’
