Prerequisites are

Setup SQL database first and grant appropriate access

Ensure target Image has
Dot Net......Support\DotNet35\dotnetfx35.exe
Visual J#......Support\JSharp20\vjredist20se_x86.exe
JRE......Support\JRE1.6\jre-6u14-windows-i586.exe

And the setting >>>Control Panel - System - Hardware - Driver Signing: Ignore or the silent install will pause for a confirmation


If Administration is to be done from this server then include as these are needed before you can install the management consoles, the management consoles are not installed as part of the XenApp Install
Java Runtime Version 5 Update 9 required for the CMC.....Support\JRE1.5\jre-1_5_0_09-windows-i586-p.exe
Microsoft Primary Interoperability Assemblies 2005 required for the CAMC ......Administration\Delivery Services Console\setup\vs_piaredist.exe

Make sure you have already created the mf20.dsn first in the C:\Program Files\Citrix\Independent Management Architecture using the ODBC Create File DSN into that location

Sample mf20.dsn is

[ODBC]
DRIVER=SQL Server
UID=DBUSERNAME
DATABASE=DATABASENAME
WSID=SERVERNAME
APP=Microsoft Data Access Components
SERVER=SQLSERVERNAME
Description=Citrix Datastore

Run >>>>> PATHTO\unattendedinstall.exe PATHTO\mps.msi PATHTO\NathanJoin.txt or NathanCreate.txt (these are the names of the unattended install files) CTX_ODBC_PASSWORD="Enterthepassword" CTX_MF_ADD_LOCAL_ADMIN=Yes

Sample unattended answer files are...

App-V: New command line for running CMD prompts inside the bubble

Ever wanted to open a command prompt for a Virtual Application without editing the package's OSD file?  In Microsoft Application Virtualization 4.5 you no longer have to edit the virtual apps OSD to get a command prompt, just run the following command in START -> RUN:

Sfttray.exe  /exe cmd.exe "APPNAME"

This is great for running various utilities within the Virtual Apps user context like:

Regedit  - See the registry as the application sees it
Explorer  - Open and view the contents of the Q drive (see note below)

Note: To view the contents of the virtual drive using Explorer.exe, you will need to check the "Launch folder windows in a separate process" option in Explorer ->Tools ->Folder Options -> View then close and reopen Explorer.
One Caveat: This will not work with Process Monitor.  You will still need to edit the OSDs and use the prelaunch command string if you're wanting to use Process Monitor for troubleshooting.  See the Knowledge Base article below for more information:

On the xendesktop image (windows 7 client) navigate to c:\program files\citrix\virtual desktop agent and edit the file workstationAgent.exe

Add the following keys indicated in bold below the entry

<appsettings>
            <add key="LogToCDF" value="1" />
            <add key="LogFileName" value="c:\xdc.log" />
            <add key=OverwriteLogFile' value="1" />

Check through the logfile located in the root of C: called xdc.log

Some good links, hints and tips can be found here

For some reason citrix dont include this option intheir icaclient.adm template so heres one with it included.

NOTE It's an unmanaged Policy so you will need to change the fileter settings to see it

Instructions are detailed here  http://support.citrix.com/article/CTX123001

I quite often get requests to check for those sessions that are in a disconnected state in the farm and force them to logoff. In this particular scenario people wanted user profiles copied back to the server before their thin client device went through the scheduled reboot which occurred every night. Below is a vbscript that will do this.

IF you previously used APP-V applications on Windows 2003 you will need to edit the OSD file for every application and add the following entry     <OS VALUE="Win2008R2TS64"/>

Without this it will creat an error in the event log with an event ID of 3017 Could not load OSD file........

This will then show up in the console on the Windows 2008 R2 servers

Since writing this 4 years ago there are new options available. Check out the entry level Netscalers available as these would have been included in the design if there were available then.

The private hotfix is attached to this post and needs to be manually copied to each XenApp 5 Server to the "C:\program files\Citrix\ICA Client"  directory
