Citrix XenApp® is an application virtualization product from Citrix. It allows users to connect to their corporate applications from various computer systems and even mobile devices. XenApp® has grown into a complex software with ever-expanding infrastructures in place. Together with tight integrations with other systems such as Terminal Services, Active Directory, and other third-party authentication services, troubleshooting XenApp® has become more complicated.
This book teaches you how to approach troubleshooting complex issues with XenApp® deployments and understand the problem, find a fix or workaround, determine the root cause, and apply corrective steps wherever applicable. The book progresses to give you an idea about the many supportive components that play an important role in XenApp’s application delivery model and should be considered while troubleshooting XenApp® issues. It also shows you standard troubleshooting processes so that you can resolve complex XenApp® issues in a mission critical environment.
By the end of this book, you will see how and where to use supportive components that help minimize XenApp® issues. Also, we’ll explain various tools that can be useful when monitoring and optimizing entire application and desktop delivery model.

Preface
In today's world, every organization has at least one or two applications that run their entire business.
Accessing these applications becomes mission-critical if the organizations want to sustain their businesses. Any users to get their job done need access to these critical applications.
Citrix XenApp with its FlexCast technology offers a flexible solution to mobilize Windows applications with a highly secure delivery model.
As with a large number of applications nowadays, XenApp requires minimal configuration and installation decisions and an experienced administrator can configure an infrastructure in a matter of minutes or hours. Particularly because installation is a simple process, it is troubleshooting that sometimes becomes difficult. Troubleshooting is not a science, it's an art form; and behind every issue there is a cause, so you must plan for the situation.
With this book, we will cover troubleshooting preparation, general processes, and real-world examples to resolve any XenApp issue in a proper manner.
By the end of this book, you will have enough knowledge to maintain and optimize your own Citrix XenApp environment.
What this book covers
Chapter 1, Basic Troubleshooting Methodology, covers understanding problems, breaking down problems into their affected components, and finally, testing problems.
Chapter 2, Understanding the Citrix® Components
