Citrix Provisioning Server Links

Some must read links about Citrix Provisioning Server before you start playing with it.



xenapp 6 issues and tips

black screen during logon (= no logon feedback to user)

this one is annoying.  While the user is logging on to the desktop, the ICA client only displays a Black Window, untill the user is logged on.
Citrix forum thread here :
best workaround until citrix delivers a server side fix : disable citrix enhanced logon feedback. Citrix KB here , regkey is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Logon\DisableStatus (64 bit os)

server hanging during shutdown

known, fixed issue.  Servers hang during a shutdown, which is risky with sheduled reboots at night.
more info, citrix kb & citrix forum

Progressive Compression causes flickering in a published internet explorer

from the citrix forums :

1. Obtain an experimental private fix from Citrix Technical Support that will disable Off Screen Surfaces from an ICA level. This can be obtained by contacting Citrix Technical Support (if you have a support agreement) and referencing Citrix Problem Report #236384. At this time, we have a fix for XenDesktop 4.0 available and other products would require development of the fix as required.


2. Disable the Off Screen Surfaces feature from the client side by changing the EnableOSS registry entry located under:

HKEY_CURRENT_USER\Software\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Thinwire Graphics\

citrix list of recommended hotfixes :

citrix came up with a list of recommended hotfixes for XenApp 6 & Windows 2008R2 (SP1)  here : http://support.citrix.com/article/CTX129229

qfarm /load gives 20000 and no license server found

check http://support.citrix.com/article/CTX125363 & request limited release hotfix if applicable.

Client Drives Cannot be Accessed in XenApp 6.0 Running on VMWare ESX

issue between vmware tools & citrix client drive mapping.  only happens when a full vmware tools install (including vmware shared folders) has happened.
more info, here at citrix KB

hide and disable windows libraries

not exactly an issue, currently the only way i’ve found to hide & disable windows libraries is :










get rid of power shell & server manager icons for all users

only found an old skool solution for this.  Remove user access to the shortcuts before the profiles get created.  Done via GPO.  More here @ technet

default printer & devices reveals too much information

create a folder called printers.{2227A280-3AEA-1069-A2DE-08002B30309D} on a desires place in the start menu.

or publish / creaste shortcut with as command : C:\Windows\explorer.exe” ::{2227A280-3AEA-1069-A2DE-08002B30309D}

or publish / create shortcut with as command : RUNDLL32 SHELL32.DLL,SHHelpShortcuts_RunDLL PrintersFolder

install telnet client & dsa.msc

Like to have these two on all my servers for troubleshooting :

PS C:\Windows\system32> Import-Module ServerManager
PS C:\Windows\system32> Add-WindowsFeature RSAT-ADDS-Tools
PS C:\Windows\system32> Add-WindowsFeature Telnet-Client

provisioning services vs w2k8r2 system reserved partition

2 nice posts on http://www.vmwareinfo.com about provisioning Windows 2008 / Windows 7 with Citrix Provisioning services.

one post explains howto create a Windows 2008R2 server without a 100MB system reserved partition

and one post that explains how to get rid of that 100MB partition if it’s already there

Citrix Quick Launch

The citrix online plugin v11 was the last version to include the Citrix Program Neighbourhood, forcing citrix admins to migrate to configure a program neighbourhood agent site, or a web interface.   While this was a good move, this might make simple troubleshooting a bit harder.

Therefore citrix created the Citrix Quick launch.  Citrix Quick Launch can connect to a server over ICA, or to a published application.  You can even create a .ICA file with it.  download here

Edit : Citrix has updated Citrix Quick launch to version 2.1 .  Please note that you do need to have the citrix online plugin installed AND if you’re using Windows 7, you might need to copy and register TabCtl32.ocx from a Windows XP/2003 box.

software restriction policies on a SBC environment

As a best practice, you should always consider Software restriction policies to harden our SBC environment (pre Windows 2008 R2), with hash rules.
