You don’t need XenDesktop for a virtual desktop

Written by Ingmar Verheij on February 1st, 2013. Posted in XenApp (Presentation Server), XenDesktop

XenDesktop 7For years Citrix has a product to host applications from a centralized locations offering great flexibility and efficiency, called Citrix XenApp. In 2008 Citrix released XenDesktop, the VDI solution from Citrix. With this first release of XenDesktop it was possible to (only) publish a desktop hosted on a single user operating system (like Windows XP, Vista or 7).

Citrix has tried to choose an appropriate name for their products to help customers understand what product offers what solution (and reducing the ridiculous times they rename their products). Although this is an admirable attempt they failed to reach that goal.

A lot of customer assume that with XenApp they can (only) publish applications and with XenDesktop (only) desktops, how wrong can they be?

The Citrix Receiver (XenApp plugin / Online plugin / ICA Client / WinFrame client) has a file association with the .ICA extension. This means that each time you open a file with the .ICA extension the Citrix Receiver is launched to interpret the file (and act upon the content of the file).

In this article I’ll explain how the .ICA file is constructed, what sections and properties are commonly used and how you can create the file.

Receiver 11.05 for Windows CE fixes disappearing smartcard in Citrix session (UZI pas)

UZI pas

Last year I wrote an article about a smartcard (UZI pas) that couldn’t be used from a Windows CE 6 thin client in a Citrix XenApp environment. The problem seemed to be solved with a private client and installing Hotfix Rollup Pack 6 on the server.

Months later, when the customer started testing again, we discovered a new issue: The smartcard reader device disappeared from the session!

It took 4 months and 5 Citrix support engineers (Ross, Shane, Romulo, Brian and finally Anthony) before we solved the issue with an updated Citrix Receiver for Windows CE 11.05 (I’ve provided the files below).

Set Citrix policies via PowerShell

Written by Ingmar Verheij on June 13th, 2012. Posted in XenApp (Presentation Server), XenDesktop

Since Citrix XenApp 6.0 and XenDesktop 5.0 policies are configurable via a new method. As a bonus Citrix made it possible to configure the policies via Group Policy Objects (GPO’s) in Active Directory.

This is especially useful if you want to set Citrix policies unattended, or automated. This way you can use it in a deployment or incorporate it in your own (provisioning) tool.

In this article I’ll explain how you can set Citrix XenApp 6.5 policies in a GPO via a PowerShell script from a remote machine. You can execute the commands from any domain joined machine, there’s no need to execute the script from a Citrix server or Active directory Domain Controller.
