Client to Server Content Redirection no more working because of License Error
Recently I faced a really strange error with a weird solution. Because I didn’t found this on the web I post this here, maybe it can help someone else too.
We had the issue that users cannot use anymore the Client to Server Content Redirection, means they can’t double-click anymore on *.vsd files to open the file with the XenApp server installed MS Visio.
After some minutes of investigation and checking the Logs on Client, XenApp server and so on we’ve finally checked the EventLog on the Webinterface server and found the following error:
Event 31007
Site path: C:\inetpub\wwwroot\Citrix\PNAgent. The Citrix servers are not licensed to support workspace control. This message was reported from the XML Service at address http://myserver.ch:8080/scripts/wpnbr.dll [com.citrix.xml.NFuseProtocol.RequestReconnectSessionData]. [Unique Log ID: a5e760c4] For specific information about this message, see the Web Interface documentation at http://support.citrix.com/proddocs/topic/web-interface-impington/wi-log-messages-event-ids-hardwick.html.
Now we remembered that we consolidated some Citrix license server’s and changed the license server for this farm some days ago. Of course we rebooted all XenApp servers, but not the Webinterface servers because they don’t use a special license server. A reboot of the Citrix Webinterface server solved this issue.
XenDesktop & XenApp FMA (7.x) HealthCheck – Oops!… I Did It Again
Some months ago I’ve created the Citrix PVS Health-Check Script which is a based on the idea and some parts of code from the Health-Check Script for XenApp 6.x of Jason Poyer (http://deptive.co.nz/) .
Because now XenApp 7 with the Release 7.6 is finally in a state where considering an upgrade of the 6.x farms make sense, I belief that the demand for a XenApp 7.x Health Check Script grows.
So I did it again and took the “HealthCheck framework” to build a new version which combines the Power of the Citrix PS-Snappins for XenDesktop/XenApp and the HTML-Output-Script of the existing HealthCheck Scripts.
The result is a new HealthCheck Script which is usable for XenApp and XenDesktop 7.x and what makes me also happy, with only a few line of more code the Script is downwardly compatible for XenDesktop 5.6 environments.
This is just the first version and I’m sure that more check’s need to be added. Feedback and “Feature requests” are welcome … And to be honest I have not yet a big environment to test my Script, so please be insightfully if you find some bugs and report them to me.
In the first part of the Script you are able to configure some parameters. You can decide if you only want to see the “bad” Desktops on which something it’s going wrong or if you want see everything. In huge XenDesktop environments you want definitely only see the bad machines … ( $ShowOnlyErrorVDI = 1 ) Also you can decide if you want only report XenApp or only XenDesktop or both. The Desktops and XenApps are in two different Tables. It’s also possible to exclude Collections ($ExcludeCatalogs) from the Check, so virtual Desktops which are for testing purposes are not checked.
If you have a feature request or a bug report please post it direct on GitHub.
Update 12.05.2016 (Version 0.95):
– Check CPU, Memory and C: of Controllers
– XenApp: Add values: CPU & Memory and Disk Usage
– XenApp: Option to toggle on/off to show Connected Users
– XenApp: DesktopFree set to N/A because not relevant
If you need a Health Check Script for XenApp Version which are older than XenApp 7.x see http://deptive.co.nz/xenapp-farm-health-check-v2 where it’s an excellent work and the inspiration for my HealthCheck-Scripts!
The code is on GitHub:

Citrix PVS HealthCheck
Problem: There is currently no free tool to check the health status of a Citrix Provisioning Services farm with all Citrix relevant parameters. There are monitoring tools which tell you if a server is up and running or if it’s not, but now tool who gives you a special overview for Citrix Provisioning Services according to how much targets on which server, how much communication retries on which target an so on.
Solution:
Since some year’s I’m using the XenApp Health Check from Jason Poyner (deptive.co.nz) to get daily a status of my environment(s). I really appreciate the work from Jason, if you don’t know it until now, you really need have a look on his blog and on the Script . The mentioned XenApp Farm Health Check Script gave me the inspiration to create a similar Health Check Script for my Citrix Provisioning Server farm. To be honest, and I’m happy that Jason doesn’t mind, that I have “recycled” some parts, or say the “framework” of his XenApp Farm Health Check script to build my Script.
The script I built can be scheduled with a Windows task which trigger a run once a day and send out a email with the attached HTML-Report:
I’ve written the Script to perform the checks in 3 Parts:
Target Devices:
- Ping
- Retry (Threshold configurable, default is 15)
- PVS Disk (Value which I read from PVS farm with get-mcli)
PVS Disk (Value which is written in the personality.ini on the Target)- PVS disk version (V1.2)
- The vDisk-Store *
- PVS Server
- WriteCache Size
* like you can read in my BlogPost “Achieve fastest Citrix Provisioning Target Device” I propose to have the vDisk Store local on each provisioning server. So I can check with that column if the Target is booting from the correct vDisk store. The Master Store is on CIFS and only used for updates of the Image.
vDisks:
- Replication state (PVS don’t replicate anything – but can check if the vDisks on all servers are equal)
- DeviceCount to see how many targets are currently reading from this Image
- Load Balancing algorithm
(Green if Best Effort because I want to have subnet affinity – feel free to change for your need. I have two data centers with two separated subnet’s – so I can guarantee that each target stream from his own data centre as long the server is available. Just in case of an outage of all PVS server in one DC it fail over to the other DC ) - WriteCache Type
- Name & Date of the vDisk
PVS Servers:
- Ping
- Active
- How many device are connected
Don’t forget to register the PVS SnapIn DLL e.g. with .Net Framework 2.0 with the command:
“C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe” “C:\Program Files\Citrix\Provisioning Services Console\McliPSSnapIn.dll”
Otherwise you get a blank output. If you have another .Net Framework version or path, please adjust the path in the command!

Update 12.11.14: Now in version 1.2 it’s possible to define the device collection which should be checked. An other additional feature is that the script shows the version of the vDisk.
Update 15.08.15: Now in version 1.4 it’s possible to have more than just one vDisk store.
Update 16.09.15: Now in version 1.5 the vDisk file name, it’s date and the count of the used disk will be showed.
Update 14.10.15: Version 1.61 New feature, PVS Cache (on disk or Ram) will be reported. / 20.10.2015 1.62: fixed some bugs (see comments)
Update 29.12.15: If you use PVS 7.7 or higher check out the new blog post with the 7.7 Script: http://blog.sachathomet.ch/happy-new-script-pvs-7-7-healthcheck/
Because of the Release of PVS with the new PoSh API the further development of this Script is discontinued. Sorry.
Create published applications XenApp to each server
For testing purposes it can be helpful to have a published application without loadbalancing to every single server of your Citrix Farm. The creation of such application can be easily done with the following example script which create a CMD on every farm server:
Add-PSSnapin Citrix.XenApp.Commands -ErrorAction SilentlyContinue $serverlist = Get-XAServer #Get all server from farm #Mainprogram # loop through all servers foreach($srv in $serverlist) { echo $srv.ServerName New-XAApplication -BrowserName "cmd on $srv" -ApplicationType "ServerInstalled" -DisplayName "cmd on $srv" -FolderPath "Applications/Published Apps/z_admin" -ClientFolder "Administration\cmd" -Enabled $true -CommandLineExecutable "C:\Windows\system32\cmd.exe" -WorkingDirectory "C:\Windows\system32" -AnonymousConnectionsAllowed $false -AddToClientStartMenu $false -InstanceLimit "-1" #-WindowType "1024×768" -ColorDepth "Colors256" Add-XAApplicationAccount -BrowserName "cmd on $srv" -Accounts "domain\USER1" Add-XAApplicationAccount -BrowserName "cmd on $srv" -Accounts "domain\USER2" Add-XAApplicationServer -BrowserName "cmd on $srv" -ServerNames $srv.ServerName }
By the way … if you made a mistake you can remove the created applications by the same foreach-loop with Remove-XAApplication:
$serverlist = Get-XAServer #Get all server from farm #Mainprogram # loop through all servers foreach($srv in $serverlist) { echo $srv.ServerName Remove-XAApplication -BrowserName "cmd on $srv" }

“Cannot complete your request‘” on Netscaler Gateway VPX
In my lab environment I was using a Citrix Webinterface 5.x which was accessible from Internet over a Access Gateway 5 VPX. Since Citrix Store Front is in a fairly usable release (> Version 2.x), I intended to update my lab environment to the current software releases and update my skills to Store Front and Netscaler Gateway VPX.
You can find a step by step Netscaler Gateway intro here http://blogs.citrix.com/2013/07/03/citrix-netscaler-gateway-10-1-118-7-quick-configuration-wizard
Also a very nice guide you can find here, this guide also contains information about how to configure StoreFront for Netscaler Gateway VPX: http://benjamin.eavey.com/2013/07/netscaler-vpx-as-secure-gateway-replacement
Cannot complete your request
After completion of the configuration I was not able to access the my environment from outside. The login to the Netscaler Gateway, the black window, was working fine, but as soon I hit the StoreFront I get this Error:
Because StoreFront is working fine from internal, I assumed that’s not a completely wrong StoreFront configuration. After i had a look into the event viewer on the StoreFront server I can see that something is wrong here:
The crucial indication that’s a problem between the Store Front server and the the Netscaler Gateway in role of Authentication Callback Server I found here:
when I browse to the address https://192.168.x.x/CitrixAuthService/AuthService.asmx you can see a certificate error, so I need to have here a FQDN that match to the installed certificate but I wont communicate outside, so first I’ve defined the internal IP as Callback URL:
Now I’ve changed the Callback URL to the FQDN appropriate to the certificate:
But because the DNS resolve this URL as the external IP which is not accessible over the necessary TCP ports, I was constrained to do a dirty hack … I have edited my host file :
Achieve fastest Citrix Provisioning Target Device
Citrix Provisioning Services is in my point of view an incomparable way to deliver a Software image to a system. It’s not a kind of an known enterprise software deployment, rather it’s a way to stream a virtual disk during runtime to hardware. Beside of PVS, the acronym of Provisioning Services.
This article doesn’t explain what’s PVS and how it works. It only shows my personal best practice to have the fastest PVS target device. It’s maybe not the only one and right solution to work with PVS, e.g. for VDI other approaches would match better. In the last couple of years I was working on multiple projects to introduce PVS OS streaming for XenApp servers on physical hardware or virtualized servers. The following instruction shows my way to deliver the fastest PVS Target for read-only XenApp servers, or in the XenApp replacement this role is Xen Desktop 7.x App Edition called .
In this article I only mention performance relevant topics, I will not talk about HA, continuous availability or about PXE, TFTP and so on.
#1. Reduce reads from disk, make use of Standby Memory for vDisks
The best way to increase performance is to reduce work, in this first step it’s to reduce the hard disk read by reading virtual hard disk files (VHD’s). This can be achieved by make use of the Windows disk cache, this approach is possible on physical PVS servers and as well on virtualized PVS servers on any hypervisor. Using the Windows disk cache means that files which are read from disk, are cached in Standby memory of the Server.
(If you are using XenServer as hypervisor have a look to the IntelliCache feature, http://blog.citrix24.com/how-does-intellicache-work. )
To make use of the file cache you need:
- The vDisk on local drives, no CIFS share, no NFS share.
- A plenty of memory to the PVS.
Having the vDisk’s on local disks is not the common way to work with PVS, keep in mind that you have to synchronize the files on all servers in PVS farm.
You can check if the file cache is used properly by having a look in the resource manager. If you have nearly no free memory and have a lot of use standby memory it’s a good sign:
To have a deep dive look in the cache use RamMap and keep an eye to File Summary:
#2. Use Target Device Write Cache on Ram
The second second way to increase performance is to use fastest possible storage, hard disk drives are quite fast today, solid state disks are faster but Ram is still the fastest memory. Because we need on the Target device only the Write Cache it doesn’t matter that the Ram is a transient memory.
A short performance comparison:
With AS SSD Benchmark you can measure the speed of your disk.
Target Device with WriteCache on Ram:
Target Device with WriteCache on local disk:
( AS SSD Benchmark is Freeware and you can download and donate on: http://www.alex-is.de/PHP/fusion/downloads.php?cat_id=4&download_id=9 )
Keep in sight the Memory
When you working with Write Cache in the Target device Ram you must appreciate the dangers of it … If you are running out of WriteCache the Target Device, perhaps a XenApp server with 50 users on it, will reboot immediately .
(By the way … Citrix Provisioning Services 7.1 offers a great new feature, it’s the possibility to Cache to Ram with overflow to hard disk. Do not use it … it doesent work proper! Waiting for a hotfix.)
- Plan the amount of real used Memory:Think how much of the Ram you will use for WriteCache, give as much as possible and consider the real memory usage of a fully loaded server. e.g. if you have a XenApp server as Target device with 16GB of Memory you can allocate 6GB for WriteCache and have still 10GB Memory for the XenApp servers. If you have special memory hungry application on the server you need maybe an other segmentation. It doesn’t exists a recipe, have a look on your currently productive servers about the used memory.
- Reboot your Target device periodically to reset the used cache.
- Reduce usage of Write Cache by redirecting as much as possible to an other disk drive, of course this is only possible if you still have a local disk attached to the Target Device.Good candidates to redirect are:
- Printer Spooler
- Pagefile
- EventLog
- EdgeSight database
- Monitor your Write Cache, a way to do this is e.g. using this small Powershell script on the PVS server with a scheduled task:
(If you have PVS 7.1 with the newest Hotfixes I recommend to use WriteCache on Ram with overflow to hard disk)

#3. Avoid if possible cross Data centre streaming
- If you have different subnet’s, make use of subnet affinity in the load balancing configuration on the vDisk.
- If you have one subnet over more data centres, create a store with the vDisk for each data centre and let only provide servers from the corresponding data centre this store. With this way you can still switch fast to a cross data centre configuration in a case of a PVS server outage in a data centre.

Issue by creating a PVS 7.1 farm
If you try to create a new Farm and the Provisioning Services Configuration Wizard stuck on a “Not responding” during the Database Server step maybe you have to many databases on the Server:
Workaround: Use the DbScript.exe to get the Database creation script and create the database with this script directly on the DB server:
Citrix DSCHECK doesen’t work … “No resource module ImaMsgsUI.dll found.”
When you try to make a Citrix Datastore validaiton with DSCHECK you receive the error message :
” No resource module ImaMsgsUI.dll found. “
Cause:
Probably you are on a Citrix server with UAC,
Solution:
Launch the command line with administrative privileges, “run as administrator” before you make the dscheck.

Check Citrix XenApp published application properties with a PowerShell script
To avoid troubles with session sharing, you have to keep in mind that you set the application properties which are relevant for the session and his virtual channels in the same way.
This is for example the properties like color depth or the audio setting.
To check this, I’ve written a small PS script which loops trough all application, reads the application properties and shout if something is not like expected.
Show all apps which are not published as 32bit Color:
#======================================================================== # Created on: 5.11.2013 # Created by: Sacha T. http://blog.sachathomet.ch # Filename: apps_not32bit_Office.ps1 #======================================================================== write-host "This Script show all Apps in Workergroup National which are not in 32 bit color depth published" Add-PSSnapin Citrix.XenApp.Commands #$applications = Get-XAApplication #Gets the published applications $applications = Get-XAApplication -WorkerGroupName National foreach($app in $applications){ #Check to see if the application audio is disabled if($app.ColorDepth -ne "Colors32Bit"){ $app_no32b+= "$app is not published in 32 bit.`n" } } echo "`nApps not 32bit: " echo $app_no32b Write-Host "Press any key to continue …" $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
Change the green Workergroup to your workergroupname, it’s also possible to run this script without the parameter -WorkerGroup, but then all published content will be recognized as “non-32-bit”.
If you want see which application has audio disabled just change the attribut in the loop:
---<snip>--- foreach($app in $applications) { #Check to see if the application audio is disabled if($app.AudioType -eq "none") { $app_noaudio+= "$app audio is currently disabled.`n" } } echo "`nApps Audio disabled: " echo $app_noaudio ---<snip>---
This easy loop you can recycle to check every application attribute, all possible attributes of an app you can get with an
Get-XAApplication -BrowserName "thebrowsernameofourapp"
Have a look into the StoreFront 2.x Subscription Database
Last days I had to deal with Citrix StoreFront 2.0 and found out that a numerous issues still exists and that some things are still not implemented to configure in the StoreFront MMC SnapIn.
Session timeouts and settings like enable or disable of features like workspace control still must be handled over the config-files. But this is all well documented the official documentation of Citrix.
But seems there is no possibility to have a look into the subscription database from Citrix Storefront which is now with version 2.0 in a proprietary non-MSSQL format. For this reason I created this small script (execute it on the StoreFront server):
#======================================================================== # Created on: 22.10.2013 # Created by: Sacha T. blog.sachathomet.ch # Filename: GetSubscriptedStoreFrontApps.ps1 #======================================================================== #define some variables #$domainname = "anotherDomain" # use that if your user is in another domain $domainname = $env:userdomain $storename = "StoreFront" # Change this to your Store-Name $subinfofile = "C:\temp\temp-subscriptions.csv" Write-Host Query StoreFront apps in domain $domainname in Store $storename $username = Read-Host "Please enter username to query" #Add Module for Citrix StoreFront Import-Module "C:\Program Files\Citrix\Receiver StoreFront\Scripts\ImportModules.ps1" #Change username to domain SID $objUser = New-Object System.Security.Principal.NTAccount($domainname, $username) $strSID = $objUser.Translate([System.Security.Principal.SecurityIdentifier]) #delete old Subcriptionexportfile Remove-Item $subinfofile -ErrorAction SilentlyContinue #Create new Subcriptionexportfile Export-DSStoreSubscriptions -StoreName $storename -FilePath $subinfofile ##Add a caption to the file, this is needed to process csv $content = Get-Content $subinfofile Set-Content $subinfofile sid.app Add-Content $subinfofile $content #Read all Lines in CSV from this User which are not unsubscribed import-csv C:\Temp\temp-subscriptions.csv -delimiter "."| Where-Object {$_.sid -like "$strSID*" -and $_.app -notlike "*unsubscribed*"}| Format-Table -Property app #wait to read the result - usefull if started from WindowsExplorer with "Run in PowerShell" Write-Host "Press any key to continue …" $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
When I’ve created this script I found out that deleted apps wont be removed from the subscription database and as well users who leave the company will still have records in the database after they are deleted in the AD. So within the years, the subscription database will have a lot of orphan data in the database. Seems that an automated clean-up does not exists.
There is a way to delete the records, have a look to forum post of Duncan Gabriel Thread:
Delete user subscriptions? http://forums.citrix.com/thread.jspa?threadID=334609
