Session prelaunch and session linger The session prelaunch and session linger features help users quickly access applications by starting sessions before they are requested (session prelaunch) and keeping application sessions active after a user closes all applications (session linger). These features are supported for Server OS machines only.
By default, session prelaunch and session linger are not used. A session starts (launches) when a user starts an application and remains active until the last open application in the session closes.
Unregister the service using the previous instructions.
Copy the files ctxxmlss.txt, clm.dll, wpnbr.dll to the \Inetpub\Scripts folder. ***(If you are running MetaFrame Presentation Server 3.0 then the clm.dll file is no longer needed).***
If you are running MetaFrame Presentation Server 3.0 or Citrix Presentation Server 4.0, locate the file ctxadmin.dll and copy it to a folder called ctxadmin under \Inetpub\Scripts.
If you are running Citrix Presentation Server 4.0, locate the files ctxconfproxy.
The system requirements in this topic are valid when this product version released. System requirements components not covered in this topic (such as StoreFront, host systems, receivers and plug-ins, and Provisioning Services) are described in their respective documentation.
Important: Review the Prepare to install topic before beginning an installation.
Unless otherwise noted, the component installer deploys software prerequisites automatically (such as .NET and C++ packages) if they are not detected on the machine.
Zones within Citrix infrastructures are logical segments within a Citrix farm. Every zone has a data collector (described in the next paragraph). Servers in a zone will communicate with his zone data collector where the data collectors of every zone will exchange information which each other about his zones.
When determine the needs for zones and the amount of zones used the following considerations:
Available bandwidth When there is limited bandwidth available the traffic between the servers within one zone can be too much for the network link.
Application Streaming Application streaming simplifies application delivery to users by virtualizing applications on client devices. Administrators can install and configure an application centrally and deliver it to any desktop on demand.
Use the application streaming feature to install and configure an application on one file server in your App Hub, publish the application using the XenApp publishing wizard, and deliver it to any desktop or server on demand. To upgrade or patch an application, you make the updates only in the location where you stored the application.
When we install any software just by double clicking it, it creates some keys in HKLM and HKCU hives. There might be some settings or keys written to HKCU hive when installing a particular software and if that needs to be applied to all the users who use that software, in normal scenario of double clicking the setup.exe doesnt work. Hence, we need some monitoring tool which monitors all the changes to HKLM and HKCU hives and apply HKCU keys to all users who ever logs in.
Problem: We have published an application in citrix. As most of the companys do, our profile directories are redirected to network share(say G: \\server1\%username%$). The application we published generates some reports and it saves to G:\Appfolder. Now when user opens the ica file in his own computer, application starts and it pulls the G: into the citrix session and the reports will get saved in the folder I gave above. All of a sudden, while generating report the application throws an error, G:\Appfolder doesnt exist or cannot be contacted.

Citrix MetaFrame XP is a remote access/application publishing product built on the Citrix Systems’ thin client protocol and used to connect to any Virtuozzo-based Container.
PVS runs on dedicated servers (VM or physical) and is pretty heavy on network io and should be designed properly while MCS needs nothing more than hypervisor snapshots which, by know, we already have.
When we are going to implement physical targets for both VDI and RDS we need PVS. MCS integrates on the hypervisor storage layer and therefor can’t be used on physical targets. This is the simplest decision of them all!
Let’s look at the different ways we have to drain users from XenApp servers.
Drain maintenace
When dealing with environment that is shared by multiple users, concept of drain-mode maintenance is very important. Drain-mode maintenance is used in scenarios where you cannot move the resources – two most typical examples are VMs that are hosted on local storage (without storage motion capability) and scenario where single operating system is providing environment for multiple users (session motion is technically not possible – don’t want me to get started talking about mutexes and semaphores).
