Missing XML file for Offline-Plugin 6.0.1 for Merchandising Server

If you are already working with Merchandising Server, you will probably know this problem.

Citrix provides an update for his Offline –Plugin that eliminates 45 bugs. The update 6.0.1 is available as regular download since many weeks now but if you try to find the update on your Merchandising Server you won’t find it. Even a manual rescan of the available plugins doesn’t help 🙁

The reason is a missing XML file, which Merchandising Server needs to control the installation and configuration of the plugins. Apparently Citrix won’t make this XML file available to the public, see Citrix Blog: App Streaming-6.0.1 LCM Update

I have therefore taken the time to have a look at the following resources:

Citrix-TV
Citrix eDocs
Metadata Reference

and finally created my own XML file.

To save your time, I will provide you with the XML file needed here: XenAppStreamingMetaData.xml

On the Merchandising Server it is now possible to upload the actual Offline-Plugin together with the new XML file. After that step you can deploy the update through standard deliveries as usual.

Why Citrix doesn’t provide this file itself is a miracle to me. In fact this behavior doesn’t help to convince people to use Merchandising Server. I hope Citrix is rethinking the way they provide updates to Merchandising Server in the future…

AAC and IE 8.0

Some days ago, Microsoft officialy released IE 8.0. Since IE 8.0 will be available trough Windows Update soon, more and more users will hit existing AAC deployments with this browser. Unfortunately this is not working as expected. This is, how an AAC portal page looks like in IE 8.0 with default settings:

Portal
OWA

The layout is crushed, links are missing and OWA is nearly unusable 🙁

A small change in the file C:\Inetpub\wwwroot\CitrixSessionInit\NUI.aspx solves the display issue by forcing IE 8.0 into IE 7.0 compatibility mode.

It is sufficient to add the following line in the header of the NUI.aspx file:

<meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE7″ />

Your header might look like this after the change:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Citrix Access Gateway</title>
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1" />
<meta name="CODE_LANGUAGE" content="C#" />
<meta name="vs_defaultClientScript" content="JavaScript" />
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5" />
<link rel="SHORTCUT ICON" href="themes/default/images/favicon.ico" type="image/vnd.microsoft.icon" />
<base id="baseElement" href="" runat="server" />
<link id="cssElement" rel="stylesheet" href="" runat="server" />
<!--[if IE]>
<style type="text/css">

Immediately your portal is rendered again as it should be 🙂

Portal
OWA

This is not a final solution for the problem, but until Citrix releases a fix for this issue it will do…

Update – AAC tuning, part 4

I had to upgrade the document, because a customer wanted to set the color of the bar to a dark blue. The caption inside the bar could not be read anymore after this change, so we had to change the color of the caption to white. This way we got the contrast needed back. How to do that is added to the document now.

The howto is written in german. A translation into english is not available at the moment. Since the pdf utilizes a lot of pictures, you might be able to understand it anyway. As soon as i find the time, i will provide a translated version. Until then, you can download the german version here: AAC4_5_CustomizeLogonPoint_Rev1.1_DE.pdf

AAC hotfix AAC450W003 and CAG hotfix 4.5.7 available

A few days ago, Citrix released the hotfixes AAC450W003 and hotfix AG2000_v457. Beside a couple of bug fixes, there are some really interesting things in these releases:

Hotfix AAC450W003 invalidates some parts of my last posting in “AAC tuning, part 3”. A couple of months ago, i asked Citrix to allow customers to change the caption of the RADIUS input box on the logon page. In my last article i showed a way to change the caption easily for RSA and SafeWord deployments and pointed out a way to change the text with a little script in case of another RADIUS solution. However this solution had some unwanted side effects and so i’m glad that Citrix came up with a solution for all deployments. The procedure described in the first section of “AAC tuning, part 3” stays valid but is now applicable for all RADIUS deployments too, given you installed hotfix AAC450W003 correctly.

Vista is now supported with AAC 4.5, but it is still beta. This means, that you are now able to check Vista clients through EPA-scans, provided by Citrix. My first tests have been successfull. CAUTION: If you use EPA-scans from EPAFactory/Accario you have to wait for an update from Accario to support AAC 4.5 HF03. This should be available around the 20th of Mai.

The list of supported AV scanner and personal firewalls has become a little longer. McAfee 8.5i, Symantec AVE 10.0, Symantec Endpoint Protection 11.0 and Trend Micro 8.0 are now officially supported at last.

The download and readme for AAC can be found here: CTX117123, AAC45W003

The download and readme for CAG 4.5.7 can be found here: CTX117123, Hotfix AG2000_v457

Update: PNAgent Filter for Web Interface 4.6

Not long ago, i had to implement the PNAgent Filter for Web Interface 4.6. It turned out, that the code itself of the modification didn’t need any changes from WI 4.5 to WI 4.6. To allow for an easy implementation, i nevertheless created an updated archive of the modification and updated the files for WI 4.6. Therefore all it needs is to replace one file, without the hassle to copy and paste code blocks to the right locations.

Download FilterApps4.6

This modification gives an administrator the power to hide Published Applications from the user. The only thing he has to do is adding a “#” sign in front of the application description. Very handy, if you use PNAgent to populate the Desktop and Start Menu and do not want the published Desktop to appear in the context menu of the PNAgent in the taskbar.

Access Gateway hotfix 4.5.6

Citrix released HotFix 4.5.6 of the Access Gateway Standard, which eliminates another couple of bugs. Before the update to version 4.5.6 the number of connections from the Secure Access Client and Citrix Presentation Server Clients could be different in the Real-Time Monitor or on the Statistics tab in the Administration Tool. Another fix adresses this issue: When users are logged on to the Advanced Access Control option through the Access Gateway, when users logoff, the session is not disconnected. Users must manually disconnect by right-clicking the Secure Access Client and selecting Disconnect.

If the Access Gateway appliance is upgraded to version 4.5.6, and Access Gateway Advanced Edition with hotfix AAC450W001 is installed on a server in the internal network, users are prompted to install the ActiveX control each time a connection is created. Currently, the file web.config has the following at the end of the file:

<add key="SACCodebase" value="net6helper.cab#version=4,5,0,122" />
</appSettings/>
</configuration/>

The version number needs to be changed to the correct version and build number for 4.5.6, which is 4,5,6,111.

The full list of fixes and the download can be found here.

Access Gateway hotfix 4.5.5 Rev. B

After the summer holidays and several very busy weeks, i have found the time again to carry on with these pages 🙂

Citrix released Revision B of the Access Gateway HotFix 4.5.5 today, which eliminates a couple of bugs. After the update to version 4.5.5 some CAG Standard installations experienced a freeze every 10 to 20 minutes or even worse 2 to 3 crashes/reboots a day. The “reason” for this behavior was the configuration of more than one STA on the CAG Standard. After the update to Rev. B this bug should be eliminated.

Additional fixes for the SAC roll out and the EPA download are included. Furthermore the SAC should close now more reliably in AAC deployments. The full list of fixes and the download can be found here.
