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:

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”

Having issues with print redirection on Citrix Workspace for Mac OS? Try installing the HP Color LaserJet 2800 Series PS print driver on your terminal server (Server 2019 and newer). It sounds dumb, but Citrix Universal Print Driver (UPD) uses Postscript data that is developed by HP. You can read more about this in the Citrix article at the end of the page.

To install this print driver, open printmanagement.msc on your VDA. Open up Print servers > Servername > Drivers > Add Driver

Select x64

And then Windows Update to check for drivers through Windows Update service.

If you don’t find the driver, manually download it through Windows Update Catalog, extract it with Winzip or 7Zip and select Have Disk…

Migrating the Citrix Site database to a new database server is pretty straight forward but needs to be planned since there is a downtime when making the switch.

First of all, take a backup of the database with SQL Server Management Studio and restore the database on the new server:

Select the file that has just been backed up.

Run a new query with CTRL + N and add the DDC’s (Delivery Controller) computer account:

create login [domain\ctx1$] from windows

Make sure the computer account has proper roles under Security > Logins > domain\ctx1$ > right click > properties (the computer account needs to have all permission ending with _ROLE in all three databases).

Step 1 is to remove the old database connection string:

Add-PSSnapin Citrix*
Set-LogSite -State Disabled
Set-MonitorConfiguration -DataCollectionEnabled $false
Set-LogDBConnection -DataStore Logging -DBConnection $null
Set-MonitorDBConnection -DataStore Monitor -DBConnection $null
Set-MonitorDBConnection -DBConnection $null
Set-AcctDBConnection -DBConnection $null
Set-AnalyticsDBConnection -DBConnection $null
Set-AppLibDBConnection -DBConnection $null
Set-ProvDBConnection -DBConnection $null
Set-BrokerDBConnection -DBConnection $null
Set-EnvTestDBConnection -DBConnection $null
Set-SfDBConnection -DBConnection $null
Set-HypDBConnection -DBConnection $null
Set-OrchDBConnection -DBConnection $null
Set-TrustDBConnection -DBConnection $null
Set-ConfigDBConnection -DBConnection $null -force
Set-LogDBConnection -DBConnection $null -force
Set-AdminDBConnection -DBConnection $null -force

Step 2 is to check whether you are able to connect to the new database server. If that does not work, the SQL Server Ports (UDP 1434 for SQL Server Browser and a high port for the SQL server instance) need to be enabled in Windows Firewall. You might also need to enable TCP/IP in SQL Server configuration manager if you are using SQL Server Express.

$SQLServer = “ctxdb\sqlexpress”
$SiteDBName = “citrixsite”
$DBConnectSite = “Server=$SQLServer;Initial Catalog=$SiteDBName;Integrated Security=True”
Test-AdminDBConnection -DBConnection $DBConnectSite
Test-AcctDBConnection -DBConnection $DBConnectSite
Test-AnalyticsDBConnection -DBConnection $DBConnectSite
Test-AppLibDBConnection -DBConnection $DBConnectSite
Test-BrokerDBConnection -DBConnection $DBConnectSite
Test-ConfigDBConnection -DBConnection $DBConnectSite
Test-EnvTestDBConnection -DBConnection $DBConnectSite
Test-HypDBConnection -DBConnection $DBConnectSite
Test-LogDBConnection -DBConnection $DBConnectSite
Test-MonitorDBConnection -DBConnection $DBConnectSite
Test-OrchDBConnection -DBConnection $DBConnectSite
Test-TrustDBConnection -DBConnection $DBConnectSite
Test-ProvDBConnection -DBConnection $DBConnectSite
Test-SfDBConnection -DBConnection $DBConnectSite

Step 3 is to set the new database connection string

Add-PSSnapin Citrix*
$SQLServer = “ctxdb\sqlexpress”
$SiteDBName = “CitrixSite”
$LogDBName = “CitrixLogging”
$MonDBName = “CitrixMonitoring”
$DBConnectSite = “Server=$SQLServer;Initial Catalog=$SiteDBName;Integrated Security=True”
$DBConnectLog = “Server=$SQLServer;Initial Catalog=$LogDBName;Integrated Security=True”
$DBConnectMon = “Server=$SQLServer;Initial Catalog=$MonDBName;Integrated Security=True”
Set-AdminDBConnection -DBConnection $DBConnectSite
Set-ConfigDBConnection -DBConnection $DBConnectSite
Set-AcctDBConnection -DBConnection $DBConnectSite
Set-AnalyticsDBConnection -DBConnection $DBConnectSite
Set-AppLibDBConnection -DBConnection $DBConnectSite
Set-ProvDBConnection -DBConnection $DBConnectSite
Set-BrokerDBConnection -DBConnection $DBConnectSite
Set-EnvTestDBConnection -DBConnection $DBConnectSite
Set-OrchDBConnection -DBConnection $DBConnectSite
Set-TrustDBConnection -DBConnection $DBConnectSite
Set-SfDBConnection -DBConnection $DBConnectSite
Set-HypDBConnection -DBConnection $DBConnectSite
Set-LogDBConnection -DBConnection $DBConnectSite
Set-LogDBConnection -DataStore Logging -DBConnection $DBConnectLog
Set-MonitorDBConnection -DBConnection $DBConnectSite
Set-MonitorDBConnection -DataStore Monitor -DBConnection $DBConnectMon
Set-MonitorConfiguration -DataCollectionEnabled $true
Set-LogSite -State Enabled

In Step 4 Citrix services need to be stopped and started (Do NOT use Restart-Service!)

Get-Service Citrix* | Stop-Service -Force
Get-Service Citrix* | Start-Service

Step 5: Check if are connections are OK

Get-AcctServiceStatus
Get-AdminServiceStatus
Get-AnalyticsServiceStatus
Get-AppLibServiceStatus
Get-BrokerServiceStatus
Get-ConfigServiceStatus
Get-EnvTestServiceStatus
Get-HypServiceStatus
Get-LogServiceStatus
Get-MonitorServiceStatus
Get-OrchServiceStatus
Get-TrustServiceStatus
Get-ProvServiceStatus
Get-SfServiceStatus

Optionally, you can check if the new connection string is configured for every service that needs the database.

Get-MonitorDBConnection
Get-AcctDBConnection
Get-AnalyticsDBConnection
Get-AppLibDBConnection
Get-ProvDBConnection
Get-BrokerDBConnection
Get-EnvTestDBConnection
Get-SfDBConnection
Get-HypDBConnection
Get-OrchDBConnection
Get-TrustDBConnection
Get-ConfigDBConnection
Get-LogDBConnection
Get-AdminDBConnection

If you are having problems with Citrix Studio and Storefront being very slow on load, this article might help.

On Studio/Storefront startup, Windows tries to verify code integrity by checking the certificate revocation list (CRL) on the internet. If the server has no internet connection, this will result in the MMC being basically unusable. To fix this, CRL checking can be unchecked in the Internet Settings (intetcpl.cpl):
