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

Roughly a year ago I had an issue with grey screen on Windows Server 2022 with Citrix Virtual Apps and Desktops. A script helped clear out some registry key but there seem to still be problems with sessions with grey screens. Check out my post from last year: https://www.ajni.it/2023/03/citrix-virtual-apps-and-desktops-2203-grey-screen-connectionfailure-in-eventviewer/

There is a new fix that seems to be better and does not clear any registry keys. Instead it activates Citrix Universal DLL Injection. After upgrading the VDA, make sure this value is set:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CtxUvi]
“UviEnabled”=dword:00000001

This helped in my environment.

As a normal user without admin rights, you can theoretically kill the Windows Guest OS (for example if you are connected through Citrix or Remote Desktop Services) by safely removing the VMXNET3 adapter on the bottom right. This is very bad and is apparently “by design”.

To hide the icon proceed as folow:

With the VM powered off, click Edit Settings > Options > General and configuration parameters. Add row and then type devices.hotplug. As a value insert FALSE. You can then power on your machine.

Updating VMware Tools on a Citrix Provisioning Master Image used to be very time consuming. Nowadays it has gotten a little better, but you still have to do a few extra steps because of the vmxnet3 network adapter. Here are the steps that I took when upgrading to the newest Vmware Tools that came with ESXi 8.0 update.

• Start the Master VM
• Once booted up, add a new E1000E network card
• Check in device manager if the E1000E/Intel network card can be seen
• Shutdown VM
• In the Provisioning console, change the mac address of the target device to that of the E1000E network card
• Disconnect vmxnet3 NIC (uncheck connect on power on)
• Start Master VM. Beware that the E1000E NIC is emulated and is painfully slow. I had instances where it took 15 minutes to boot up!
• Once booted up, start VMware Tools upgrade through Vcenter (interactive)
• Visual C++ Redistributable might be installed, you might need to reboot
• Let boot
• Start Vmware Tools upgrade again (interactive)
• Run the installer
• Shutdown VM
• Disconnect E1000E NIC (uncheck connect on power on)
• Connect vmxnet3 NIC (check connect on power on)
• Boot
• Once booted, fully remove E1000E fully
• In device manager, show hidden devices and delete the greyed out Intel NIC

This time there are no references. I had to try and error myself.

This neat software makes it possible to convert an OST file into a fully functional PST file. You can even export single items inside the OST file if you would like to. But what’s an OST file? An OST file gets created by Outlook whenever you create a new Outlook profile. It is the current locally synchronized copy of your mailbox. With this format you cannot do much. A PST file, on the other hand, is a functional archive of an outlook profile. So why is there a need for an OST converter like Stellar Converter for OST?

When your OST file becomes inaccessible or gets corrupt, you are not able to access your mailbox items. The OST file gets corrupted due to several reasons, & you will come across with below-mentioned errors:

• “Your offline folder file could not be configured \\ComputerName\FolderName\Outlook.ost”
• “The operation failed due to a registry or installation problem. Restart Outlook and try again. If the problem persists, please reinstall.”

So in this case, you need to convert the OST file to PST to get access to all your mailbox items.
