Web Interface 5.2 and Presentation Server 4.0

Error message ”Citrix online plug-in could not contact the server” when trying to access applications with the Citrix XenApp plug-in.

Recently I helped upgrading a WI to version 5.2. The customer was running Presentation Server 4.0. After the upgrade everything worked fine for all users running WI with the XenApp Web plug-in. A few users, no more than 20, was running the XenApp plug-in (The new name for the old PN agent). These users could not launch any applications 🙁

The application enumeration worked fine, but trying to launch an app would show the error ”Citrix online plug-in could not contact the server”.

After some troubleshooting I found the following solution:

Edit the WebInterface.conf file.

Change the value RequireLaunchReference=On to RequireLaunchReference=Off.

That solved the issue.

Afterwards I found this Citrix technote describing the necessity to change this value. Even though it’s not exactly the same issue:

First Non-Citrite on Citrix TV

I recently delivered a session on the upcomming Citrix feature Power and Capacity Manager for the Danish Citirx Usergroup. This session is publicly available at Citrix’s own web-channel Citrix TV. To my best knowledge, I’m the first Non-Citrite to be broadcasted through Citrix TV – I personally find that very cool 🙂

Check out the session on Citrix TV (Please be aware that the session is in Danish):

CUGtech Autumn 2009

I have just returned from CUGtech in Norway. CUGtech is the norwegian Ctirix User Group’s autumn event. It has been a great pleasure attending.The event was extremely well organized, with great sessions and friendly people.The event was held in Dr. holm Hotel in Geilo. Even though Geilo is all most 4 hours by train from Oslo, it’s a great location. CUGtech had the hotel for them self, the conference facilities was good, great food and a beautiful view.

I attended some great sessions presented by Shawn Bass, Dr. Benny Tritsch, Rich Crusco, Rick Dehlinger, Alex Yushchenko and Rene Vester. Most of the sessions was recorded and will hopefully be available on the website later.

A big thanks to the norwegian Citrix User Group for a fantastic event.
