Manage Citrix NetScaler X with IE9

NetScaler X

After an upgrade of a NetScaler from 9.3 to NetScaler X (NetScaler 10) I wasn’t able to manage it from Internet Explorer 9 (IE9).  All you would see is a grey bar on top and a white screen Bedroefde emoticon

I’’ve only been able to test this with a non-default (nsroot) username .

This is a known problem at Citrix, but unfortunately it isn’t solved (yet). Enabling or disabling the compatibility mode as described on this thread at Citrix forums didn’t solve the problem for a compete 100%. The ‘best’ workaround is to set the browser mode to Internet Explorer 8.

Should Citrix buy Lakeside Software?

Written by Ingmar Verheij on August 2nd, 2012. Posted in Citrix, Opinion article

Citrix Lakeside Software?Citrix has a history of buying companies to expand their product range (NetScaler, XenSource, App-DNA, etc.) and to improve their existing products (sepagoProfiles aka Citrix User Profiles, Ems-Cortex aka Citrix CloudPortal Services, Kaviza aka VDI-in-a-Box, etc.)

During Citrix Synergy Barcelona in 2011 Citrix announced the acquisition of App-DNA, resulting in the Citrix AppDNA product (rebranded from App-DNA AppTitude). With Citrix Synergy Barcelona 2012 coming in two months I wondered if Citrix should buy Lakeside Software and if they’ll announce it in Barcelona.

The Citrix ICA file explained and demystified

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.

“Citrix and the curse of version 6”

Once upon a time there was a successful independent software vendor based in the sunny Ft. Lauderdale, Florida.

Started in 1989 with $3 million in funding the company now has an estimated market value of $14 billion dollar.

This growth is achieved by developing products that help companies solve their issues and enable them to pursuit their goals. Products like XenApp (former Presentation Server (former MetaFrame (former WinFrame))), XenDesktop, XenServer, NetScaler, Branch Repeater, Provisioning Server and many (many!) more (product matrix).

With the release of each new version of a product more features are added,  problems are solved and raises the bar for the competition. Both companies as IT professionals embrace each new versions with a loud applause, lots of marketing and geek speaks. All version except that feared version : 6

Each time Citrix releases a version 6 of a product the experts cringe and take a step back to evaluate the product from a safe distance, with the necessary precaution.  In their minds it sounds “version 6….6…6…!”

How come? Well, do you remember XenApp 6? The version that was required for 2008R2 but got released before it was really finished (no separate roles for data collector and desktop server, and quite buggy). Or XenServer 6 (got some nasty bugs)… or Provisioning Server 6 (got some nasty bugs)…. or recently Branch Repeater 6 (6.1 is released, consider upgrading to 6.1 or skip 6.0).

XenDesktop is at version 5.6, with high expectation of new release announcements for the coming Citrix Summit/Synergy in October…

Dear Citrix,


Could you please skip version 6 for XenDesktop?
