Last week I cloned some Citrix XenApp servers by a customer, after multiple reboots I saw boot message:

VMware image customization is in progress …

Solution:

Open the Registry Editior, path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\BootExecute

Remove the value: sysprepDecrypter.exe , result:

Press OK, reboot the server and.. the problem is solved!

I’m currently working on a project with Citrix Provisioning 6.1 build 1082 / XenApp 6.5 RP1 running on a VMware vSphere 4.1 build 721871 cluster, we discovered some boot “time” problems at the target VM’s, some of our Citrix XenApp 6.5 targets take more then 5 minutes to get past the bootstrap portion of the boot process.

Solution:

BUG0321533: Booting in a VMware environment can take more than 4 minutes to get past the bootstrap portion of the boot process. This has only been reported using ESX 4.1

Download hotfix: here

1. From Provisioning Services server machine, backup the following file: ARDBP32.bin

For Windows 2008 this file is located in (default) "C:\ProgramData\Citrix\Provisioning Services\Tftpboot".

2. Copy the following file included in the hotfix folder to the "Tftpboot" sub-directory indicated above:

ARDBP32.bin

3. Back up the following files from the Provisioning Services-installation-folder\TSBboot folder (Default is C:\Program Files\Citrix\Provisioning Services\TSBboot):

TSBBDM.BIN

4. Copy the following files from the hotfix folder to the Provisioning Services-installation-folder\TSBboot folder (Default is C:\Program Files\Citrix\Provisioning Services\TSBboot):

Installed this hotfix:

Hotfix XAE500W2K8030 – For Citrix XenApp 5.0 for Windows Server 2008 x86
http://support.citrix.com/article/CTX122563

Set the following policy’s:

Citrix Policy’s: Default Policy - User Workspace – Time Zones – Do not estimate local time: Enabled
Citrix Policy’s: Default Policy – User Workspace – Time Zones – Do not use Clients’ local time: Disabled

Local policy: Computer Configuration > Policies > Administrative Templates >Windows Components > Terminal Services > Terminal Server > Device and Resource Redirection > Allow time zone redirection: Enabled

I rebooted the Citrix servers and the Client Time Zone is active for the Citrix users.

I was called yesterday that local printers and some network printers arn’t mapped in a user Citrix session. Normally you can choose and test with restarting from the Windows Print Spooler en Citrix Print Management Service but… there was no Citrix Print Management Service.

With CtxCpsvc10.exe you can Uninstall, Install the Citrix Print Management service and you can recreate the ctx_cpsvcuser user with the correct startup credentials in the service.

In my case I used: cpsvc.exe –install to install the Citrix Printer Service

Result: Citrix Printer Service installed.

Today I got many problems with my Citrix 4.5 farm, by opening Presentation Server Console i got this error:

Error code 0 (0) occurred while attempting to execute ‘C:\Program Files\Java\jre1.5.0_11\bin\javaw.exe’ with working directory ‘C:\PROGRA~1\Citrix\ADMINI~1\ctxload.exe

In de Application Eventlog I receive MSI install errors by opening Presentation Server Console:

After installing Citrix Webinterface 5.1 on my Windows 2003 R2 SP2 64-bit VM i get the following error:

ISAPI Filter ‘C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_filter.dll’ could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see http://go.microsoft.com/fwlink/?LinkId=29349.

To resolve this error you must prepare your IIS and ASP.NET 2.0 to an 64-bit application.

ASP.NET 2.0, 64-bit version

To run the 64-bit version of ASP.NET 2.0, follow these steps:

1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command to disable the 32-bit mode:

   cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0

3. Type the following command to install the version of ASP.NET 2.0 and to install the script maps at the IIS root and under:

   %SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i

4. Make sure that the status of ASP.NET version 2.0.50727 is set to Allowed in the Web service extension list in Internet Information Services Manager

Result:

Enable32bitAppOnWin64           : (BOOLEAN) False

Finished installing ASP.NET (2.0.50727).

And my Citrix Webinterface is working:

Performance technisch kan je er voor kiezen om Macromedia Flash te disablen op een Citrix omgeving. Dit kan op Farm niveau worden uitgeschakeld:

Daarnaast kan er worden gekozen om dit uit te schakelen in het register. Deze sleutel zorgt er ook voor dat er geen popups verschijnen indien er een Flash animatie gestart wilt worden of een Active X applicatie geinstalleerd moet worden.

Open binnen het register het volgende path:

HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\ActiveX Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}

Maak een DWORD aan genaamd “Compatibility Flags” met waarde: 0×00000400 (1024 in decimal)

Er zijn nogal wat problemen omtrent Windows Terminal Servers/Citrix op VMware ESX servers. Wat zijn nou de beste instellingen om performance te waarborgen.

Om dit allemaal uit te zoeken ben ik bezig geweest bij een klant die performance problemen ervaren. Deze klant heeft meerdere ESX hosts, een host heb ik gepakt om bezig te gaan met de performance problemen. De host en VM’s hebben de volgende specificaties:

ESX Host Configuratie:

Model: HP ProLiant DL380 G5

Processors: 8 CPU x 1,999 Ghz

Processor Type: Intel® Xeon® CPU  E5335 @ 2.00 Ghz

Number of NICs: 6

OS: VMware ESX 3.5 u4

I just stumbled upon the Citrix Visio stencils created by Daniel Feller

For quite a few years, I’ve developed a set of Visio stencils that I’ve used, along with many of my coworkers, to create detailed design architectures for a Citrix solution. The stencils have morphed over the years and I have now consolidated them into a single package.  This one stencil has just about everything you will need to create detailed Citrix solution diagrams.  Included are items for the following products:

• XenApp
• XenDesktop
• XenServer
• NetScaler (includes rack-mountable stencils and NetScaler MPX)
• WANScaler (including the new Branch Repeater)
• Access Gateway
• Application Firewall
• Provisioning Server
• EdgeSight
• Password Manager
• Workflow Studio

I’m always looking for ideas on what’s missing so there can be one comprehensive stencil set for Citrix solutions. Drop a comment and let me know what else is needed.
