Citrix Storefront – Adventures in customization – Customization breaks in internet explorer

2017-07-14
I ran into a frustrating issue with my last post (changing the clientname based on the application).  The issue was, it wasn’t working!  Sometimes!  On some versions of IE!  On some Operating Systems! WTF. On Windows 10, IE11 or Edge it worked fine.  On Windows 7 or Server 2008 R2 with IE11 it worked…  SOMETIMES. […]

Citrix Storefront – Adventures in customization – Assign a custom clientname to an application

2017-07-13
I have set a personal goal to avoid creating more than a single store for Storefront.  With that, I’ve been working on customizing Storefront for our organization and occasionally a problem comes up that requires a unwieldy solution…  Like creating multiple stores. An example of this is we have an application that configures itself based […]

Check for NUMA within a VM guest with Powershell

2017-07-06
I have only tested this in VMWare, but it seems to work.  I have shamelessly stole the main code from here:   [crayon-5970bc879052f425992711/] I was going to use this to detect NUMA and configure a network adapter RSS based upon NUMA configuration…   But I’m getting lazy and am going to ignore it.  But I […]

Remove Ghost devices natively with Powershell

2017-06-28
We’ve been looking at using Base Image Scripting Framework (BISF) as our new preparation and personalization platform for our PVS farm.  In our current world we have a bunch of features and tweaks that are not apart of BISF so I’ve been writing some additions so that we achieve feature parity. One of the features […]

Citrix Provisioning Services Target Device Upgrade Woes

2017-06-27
We are running Citrix PVS 7.7 and we are attempting to upgrade to Citrix PVS 7.13 for the vDisks.  Starting with PVS 7.7 you are supposed to be able to do an in-place upgrade of the tools.  Our experience with this has been less than positive, with a success rate of ~50%.  This post is […]

Citrix Storefront – Performance Testing and Tuning – Part 6 – Testing Peak Load

2017-06-13
In part 5 I figured out our peak load against our existing infrastructure.  In this part I’m going to test against a Storefront server to see if it can handle the baseline load. This is the counters used for PNA launches: The loads to test are: Peak Rates (in per second) PNA Logon PNA App Launches […]

Citrix Storefront – Performance Testing and Tuning – Part 5 – Establishing a Peak Load

2017-06-06
In part 1 I setup a script to load test our Citrix Storefront server, as a user logging in through the website.  Part 2 was users connecting via PNA.  In this part I’m going to examine our existing load.  In order to do so, I only want to count the following users: Users must have logged […]

AppV5 – System Environment Variables Gotcha’s

2017-06-05
We had an application that has its environment configured via ‘system environment variables’.  System environment variables differ from ‘user’ environment variables in that they are global so all users see them, and in a native Windows environment, they are stored in a different location; but still in the registry.  So it seemed, like everything else App-V, […]

Citrix Storefront – Performance Testing and Tuning – Part 4 – PerfMon Counters, PNA Logon

2017-06-02
In looking at the performance of the Citrix Storefront Server, one of the thing I want is to understand what Storefront is doing at each stage of a session life cycle.  There are two session-types that I’m curious about, a web browser based connection and a PNA connection.  I’m going to examine a PNA based connection […]
