Having issues with users reconnecting a disconnected Citrix Virtual Apps and Desktops session? These keys might help you. Citrix support confirmed, that they help starting at Server 2016 VDA.

Fastreconnect is a feature that was introduced by Microsoft to enhance session reconnect through RDP, but through Citrix ICA it seems that is does not improve anything.

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Reconnect
FastReconnect REG_DWORD 0

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Ica\GroupPolicy
EnforceUserPolicyEvaluationSuccess REG_DWORD 0

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 $_
    }
}

ChatGPT is an artificial intelligence language model that has been trained on a massive dataset of written text, allowing it to generate human-like responses to a wide range of queries and questions. As part of the OpenAI project, ChatGPT is one of the most sophisticated AI language models available today, capable of understanding and processing natural language input in a way that was once considered impossible.

The development of ChatGPT and other AI language models like it has been driven by a desire to create machines that can more effectively communicate with humans. With the ability to understand and generate language, these models have the potential to transform many industries, including customer service, education, and healthcare. By enabling machines to understand and respond to human language, we can create more efficient and personalized interactions between humans and machines.

One of the key benefits of AI language models like ChatGPT is their ability to learn from vast amounts of data. By analyzing large amounts of text, these models can identify patterns and relationships within language, allowing them to generate responses that are both accurate and contextually appropriate. This has significant implications for areas such as natural language processing, machine translation, and text analysis.

However, the development of AI language models like ChatGPT also raises important ethical considerations. As these models become more sophisticated, there is a risk that they could be used to create convincing fake news or other forms of disinformation. Additionally, there are concerns that these models could be used to create biased or discriminatory responses, particularly if they are trained on data that reflects societal biases.

Ultimately, the development of ChatGPT and other AI language models is a significant step forward in our ability to communicate with machines. While there are certainly challenges and risks associated with this technology, the potential benefits are vast, and it is likely that AI language models will play an increasingly important role in our lives in the years to come.

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:

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

or

HKEY_CURRENT_USER\Software\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.

If you need to renew the Always On VPN IKEv2 server certificate, here are three lines that will help you. Assuming you have the right certificate and the thumbprint, execute the following commands on the VPN server:

$cert = Get-ChildItem -Path Cert:\LocalMachine\My\ | where { $_.Thumbprint -eq “thumbprint” }

Set-VpnAuthProtocol -CertificateAdvertised $cert

Restart-Service RemoteAccess
