The XenApp planning and installation documentation uses the following terminology.
Multi-user environment
An environment, including XenApp and Terminal Services, where applications are published on servers for use by multiple users simultaneously.
Application servers
The farm servers that host published applications.
Infrastructure servers
The farm servers that host services such as the data store or the license server. Typically, they do not host published applications.
Production farm
A farm that is in regular use and accessed by users.
The ICA Client This is the original name of the client software that seemed to work fine for ten years. If we were scientists, this would be our ‘control.’ Historically there were Program Neighborhood, Program Neighborhood Agent, and Web packages available. You could use any of the three packages to connect to seamless published apps or to full desktops.
The XenApp Plugin This is the new (current) name for the ICA client.
Member servers to ZDC communication
The ZDC will send an IMA ping to each MetaFrame server periodically to make sure that they are still alive. This happens by default every 60 seconds.The ZDC also requests a load level from a server if it has not received a load update for more that 5 mimutes.
Grace Period for Data Store and License Server
Background
License Server will work normally with MetaFrame Presentation Server after the MetaFrame Server looses the connectivity to its Data Store.
RegScanner(RegistryScanner)- Scan and find values in the Registry. XDPing - The XDPing tool is a command-line based application which automates the process of checking for the causes of common configuration issues in a XenDesktop environment. More Info HERE

Check out the latest citrix support tools page for updated info: Citrix Support provides many support tools to help in the troubleshooting of an environment that contains almost all the Citrix product. All support tools are available from the following location: Citrix Knowledge Center - TOOLS
Legacy tools:
Citrix Support have been developing tools to help troubleshooting your Citrix environments for many years now. Below you will find the full list of tools available from Citrix Support along with links to useful resources.
Hi All,
Today I was given a task to get a list of all connected users to terminal servers. So, I thought I would share the process to list terminal server/citrix ica users and kill the required sessions when needed.
List ICA/RDP Sessions:
If we want to get a list of all ICA and RDP sessions list we can
Connect to the server and use the command, query session.
Use any tool to get the list of sessions.
XenApp administrators often encounter a situation which requires to take the XenApp Server “offline” to be troubleshooted. By “offline”, it means the server should not take any more new sessions while keep the existing session untouched.
Usually the administrator will use either the script or AMC to disable the logon of the server so no more sessions can be launched against that server. But disable logon also disable the capability of the remote login to the server to troubleshoot even using RDP protocol.
What and why Citrix? Citrix is a serverbased computing package that incorporates a proprietary network protocol that separates an application’s logic from its user interface allowing clients to run “thin.” Thin clients have little or no secondary storage and are used only as clients depending on the server for software, processing and secondary storage. The proprietary network protocol that allows users to use Citrix technology is the Independent Computing Architecture (ICA).
Prerequisites Explained:
We all know the prerequisites for installing Citrix Xenapp(any version). But if anyone asks us WHY they are considered as prerequisites, why they are important to Citrix? Most of us dont have answer(including me). Hence I am going to explain some of the important prerequisites here:
If we are talking about prerequisites only 3 major roles comes into picture as stated below:
Terminal Services(Remote Desktop Services). Web Server(IIS). Application Server.
