Citrix Printer Roaming…

2017-07-27T00:01:01+00:00 September 24th, 2014|Uncategorized|

If you happen to use Citrix policies to configure printer roaming in your XenApp and/or XenDesktop environment, you may have had issues with session printers.  There are a variety of solutions out there to handle printing, and even Citrix has their Universal Print Driver.  Before this was available, however, if you wanted to do printer roaming in Citrix and only Citrix, you had to use their policies.  I found my head meeting the desk repeatedly when I tried to clear up the network session printers available to an endpoint.  In this XenApp 6.5 and XenDesktop 5.6 scenario, when a user switched from using one physical endpoint to another, Citrix policy was configured to add the geographically nearest printer and make it default.

Citrix Printing

The part where the printer was added and made default worked like a charm.  I was happily able to switch between a laptop and a Wyse device in different locations and have the default printer switched accordingly.  Unfortunately, after doing this with multiple devices in an environment with multiple printers, the list of available printers started adding up.

Citrix Printing

This may be a feature that you want to keep, and let the users decide where to send their print jobs.  On the other hand, if you don’t think users need to be able to exercise free will to such an extent, you may want to have that list cleared at each connection.  To do this, there are some hot fixes you should know about.  Actually, there are quite a few possible hot fixes you could try to use to fix this problem.  I did, and it took some time to find the right one(s).

First up: Download Hotfix Rollup Pack 4 for Citrix XenApp 6.5 (http://support.citrix.com/article/CTX140111)

Note that XA650W2K8R2X64R04 is designed for x64 architecture on Server 2008 R2.

Then apply the fix to the presented desktop server(s), and make the following key in the registry of the PD:

HKLM > Software > Citrix > Ica > PrintingSettings

Then create a new Dword entry with a hexidecimal value of “1”:

DeleteNetworkPrinters         1

Citrix Printing

Simple, right?  Now any presented desktops you are using should dispose of extra session printers at each connection.  And if you are using XenDesktop 5.6, you need to make the change on the VM endpoints themselves.  In this case, install Hotfix Rollup XD560VDAWX64400 (version 5.6.400) for XenDesktop Virtual Desktop Agent Core Services x64 (http://support.citrix.com/article/CTX138551).

If your client VMs are 32 bit, get XD560VDAWX86400 (http://support.citrix.com/article/CTX138550).

Install this patch for the Virtual Desktop Agent (VDA) and then, again on the client VMs, have the same registry edit applied:

HKLM > Software > Citrix > Ica > PrintingSettings

Then create a new Dword entry with a hexdecimal value of “1”:

DeleteNetworkPrinters         1

That’s it!  Test it according to your deployment method and you should see those printers disappearing.  If you want them to stick around, change the value of DeleteNetworkPrinters from “1” to “0.”

Major Citrix Recognition!

Publishing MS Word Viewer through Citrix XenApp 6.5…

2017-07-27T00:01:03+00:00 June 19th, 2013|Uncategorized|

Recently, I moved over to the Coretek virtualization team.  It’s a great opportunity to work with new technologies and implement them as part of our Virtual Clinical Workstation solution.  

Citrix is one of the technologies that plays a major part in the solution.  As part of a virtualization implementation we are working on, I was tasked with publishing the Microsoft Office viewers through Citrix XenApp 6.5.  Now, I have a pretty extensive background in software installation and configuration on Windows desktops; however, publishing them through Citrix was new to me.  

The way a published application’s files and registry keys interact with a desktop operating system are fundamentally different.  Therefore, I was surprised to find when I attempted to open a Word document in the published Word viewer by double clicking on the .doc file — the file itself would not open, but the Word viewer would only open up an “Open” dialog.

 

1.BrowseDialog

So, being pretty new to Citrix — and given that it’s a pretty complex application that is comprised of multiple policies, application configurations, and settings, which can redirect content and drive mappings — troubleshooting issues like this can be challenging (and of course, you must also consider all the AD policies applied as well).  In the end, the solution to this particular issue was pretty simple…

Fortunately, once I was able to rule out that content redirection or drive mappings might be the cause, I found a Citrix KB article that addressed the exact issue I was having.  You can read the article here: http://support.citrix.com/article/CTX128151

In short, I had to add a special parameter (“%**”) at the end of the Word Viewer’s Command Line in the Citrix AppCenter (where published applications are stored).  The default parameter contains only one asterisk (“%*”). 

 

2.Location.Command.Line

 

Hopefully this tip will help if you experience the same issue!

 

 

 

How to create nice-looking icons for Citrix published apps

2017-07-27T00:01:07+00:00 October 17th, 2012|Uncategorized|

Problem:

A customer of mine has a handful of web applications which are published with XenApp 6.5 and PNAgent, have shortcuts on the desktop, and are launched via a URL with Internet Explorer.  So, the default icon that the user sees on their desktop is the typical Internet Explorer blue e icon for every one of them.  The customer wanted to assign a distinctive and representative icon to each of the web based applications, but didn’t have all of the icons for them.

 

How I worked through it:

We first tried to assign some ICO files that we found to those applications; but while they looked good when we downloaded them, they looked horrible when presented to the user.  The colors were way off, which looked unacceptable to the customer:

 

 

So, I searched around on the web to find out why the custom icons looked so bad, but couldn’t find a lot of concrete information about it.  I found a Citrix support article (http://support.citrix.com/article/CTX126458) that was very brief, but did say one critical thing:  any icon files assigned to published applications that are larger or smaller than 32×32 pixels will downgrade to only an 8-bit color depth.  This is what I experienced in the above screenshot of the icon for the published application.  However, if the icon file is sized at exactly 32×32 pixels, it will retain up to the full 32-bit color depth.

Given this information, and messing around a bit with some icon files, I was able to prove out a process to ensure your custom icon files will show up as expected when assigned to published applications.

 

Process:

  1. Obtain a reference file that you want to turn into the new icon
    – This file can be in at least a ICO, PNG, GIF or JPEG format
    – It is preferable to have a file that already has a  transparent background (ICO, GIF or PNG) unless the background color is acceptable or the image is meant to take up the entire 32×32 pixel canvas

    Here is an example of the icon file that I tried originally, but looked bad on the published application because the size was 64×64 pixels (please see the “How I worked through it” section above for a screenshot of what it looked like in XenApp) 

  2. Open file in image editing software (like GIMP or Photoshop)
    Optional: If the image has a background that is not transparent and you want the final icon to have a transparent background  then proceed to cutout image that you want in the final icon file and paste it onto a new canvas with a transparent background
  3. Orient the image on the canvas as needed and re-size the canvas to 32×32 pixels
  4. Edit/touch-up as necessary
  5. Export to PNG or GIF (to keep transparency)
  6. Convert to ICO file
    – Browse to www.converticon.com
    – Browse for the new PNG or GIF file that was just created
    – Export to 32×32 pixel ICO file
  7. Upload file to a XenApp server in the farm that is hosting the published application
  8. Assign the icon to published application (XenApp 6.5 specific steps)
    – Open AppCenter
    – Open Application Properties of Published Application
    – Select Shortcut Presentation
    – Click “Change icon…”
    – Select “Choose an icon from a file on an IMA server”
    – Browse for and select the ICO file
    – Click OK, then OK

Here is what the re-sized icon then looked like after I assigned it to the published application:

 Happy iconing!

 

 

Useful Periodic Citrix EdgeSight Reporting

2017-07-27T00:01:08+00:00 October 27th, 2011|Uncategorized|

I am often asked by customers, “With EdgeSight, what reports should we monitor on a daily, weekly, monthly, or yearly basis?”

EdgeSight is a powerful, but sometimes complex tool.  Based upon my experiences, there are several reports you can schedule to run on a daily basis that will give you a good snapshot of the health of your environment. 

Here is the list of daily reports which I recommend to my customers in order to monitor the health of their XenApp environment:

  • XenApp Summary: XenApp performance data (login time, active sessions, ICA session latency, and CPU and memory usage).
  • XenApp Server Utilization: Average CPU, average memory, and peak concurrent sessions for XenApp servers.  This report contains information about the most heavily loaded servers.
  • Session Client and Server Startup Duration: Average Session client startup duration (CSD) and server startup duration (SSD).  Displays login duration.

By monitoring these three reports, a XenApp administrator will be able to quickly identify if any one of the servers or users has experienced issues over the past 24 hours.  In one instance, the Session Client and Server Startup Duration report was useful in identifying a delay at login that only occurred for the first login after a reboot. 

While you will not necessarily be able to identify a root cause with these summary reports, you will have enough data to begin the troubleshooting process.
