Error in CITRIX XenApp

Citrix is the synonym for the virtualization and application infrastructure systems developed by the company of the same name. Main areas are application virtualization, Software-As-A-Service (SaaS), cloud-computing and networking. The two most well-known are Citrix XenApp or Citrix CloudPlatform.

Citrix

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Remote access may refer to the connection to a data-processing system from a remote location, for example through a virtual private network remote desktop software, terminal emulation, or the activation of features of a business telephone system from outside the business's premises.

Remote Access

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.
