Citrix Virtual Apps and Desktops 2203+ grey screen/ConnectionFailure in Eventviewer

March 19, 2023 by AJNI No Comments

Having grey screen issues with CVAD 2203+ and higher on Windows Server 2022 Terminal server? I had this issue occurring on Citrix 2212. Try running this script. It might help you out. Do a VM backup or snapshot before running the script, just to be sure.

$iddHwId = “VEN_5853&DEV_1003”
$pnpDispDevPath = “HKLM:\SYSTEM\CurrentControlSet\Enum\SWD\RemoteDisplayEnum”

try
{
    $iddDevEntries = Get-ChildItem -Path $pnpDispDevPath -ErrorAction Stop| Where-Object Name -Match $iddHwId
}
catch
{
    Write-Output “Failed to query remote ID device entries”
    Write-Output $_
    return
}

if ($iddDevEntries.Count -eq 0)
{
     Write-Output “No remote ID device entries found.”
     return
}

$iddDevEntries | ForEach-Object {
    
    $devName = ($_.Name -Split “\\”)[-1]
    
    try
    {
        Remove-ItemProperty -Path $_.PsPath * -ErrorAction Stop
        Write-Output “Cleared values for $devName”
    }
    catch
    {
        Write-Output “Failed to clear values for $devName”
        Write-Output $_
    }
}

This saved my day:

Outlook 2016/2019/365 Problems connecting to Exchange Online mailbox

January 3, 2023 by AJNI No Comments

One or a few users are not able to connect to their mailbox using the newest Outlook version there is? Well the issue might be TLS 1.2 not being active on the user’s side.

Just set this registry key and you should be good to go:

HKCU\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings

DWORD SecureProtocols 00000A80

HEX A80 or decimal 2688 enables TLS 1.0, 1.1 and 1.2, while decimal 640 only enables TLS 1.0 and 1.1.

Windows Server 2019/2022 Freezing/Very Laggy Taskbar

December 27, 2022 by AJNI 4 Comments

Having odd issues with the task bar/random task bar freezing on Windows Server 2022 RDS? Or explorer.exe using around 10% of the CPU for every user that is logged in? This might save your day. This issue occurs if you have MS Teams installed on the RDS.

First of all, export the registry path HKLM\SYSTEM\Software\Microsoft\TIP\TestResults\27641370 and look at the file size. If it is around 40MB in size, then you have the same issue.

To resolve the issue, delete the key and disable the TabletInputService service (Touch Keyboard and Handwriting Panel Service). Afterwards, take ownership of C:\Program Files (x86)\Common Files\Microsoft Shared\ink\TabTip32.exe and C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe and rename both executables into TabTip32.exe.orig/TabTip.exe.orig.

After that, reboot your server.

Expand Boot Disk in Windows Server 2022 – Delete Recovery Partition

August 16, 2022 by AJNI No Comments

Windows Server 2022 is new and has to be the best Windows Server there is right? Not at all. Microsoft has added a recovery partition (like in Windows Client versions) that prohibits you from expanding the boot disk like you usually would in older Windows Server versions.

Anyway, here are a few diskpart commands that will help you delete the recovery partition and allow you to expand the boot disk:

diskpart

list disk

select disk 0

Make sure partition 4 is the 523MB Recovery partition

select partition 4

delete partition override

Publish Click Once Applications on Citrix Virtual Apps and/or Desktops

August 15, 2022 by AJNI No Comments

Just recently I learned that Microsoft ClickOnce Applications are a pain in the ass and cannot be published as Published Applications the usual way through Citrix Virtual Apps and Desktops.

Usually the message below shows up before starting or installing the application (which is on a user basis – I absolutely hate that. Thanks for that Microsoft and Developers). If you try to publish the file ending with .application nothing will happen.

Creating a BAT file and publishing that bat file will show the prompt and the desired application will start:

cd /d “C:\Windows\Microsoft.NET\Framework\v4.0.30319”

start dfsvc.exe

start “C:\Program Files (x86)\Internet Explorer\iexplore.exe” “http://webserver/app”

This does also work:

start “C:\Program Files (x86)\Internet Explorer\iexplore.exe” “\\fileserver\share$\bestsoftware.application”
