About Secure Gateway:
The Secure Gateway for Windows helps you to secure access to enterprise network computers running Citrix XenApp and provides a secure Internet gateway between Citrix XenApp and user devices. The Secure Gateway transparently encrypts and authenticates all user connections to help protect against data tampering and theft. All data traversing the Internet between a remote workstation and the Secure Gateway is encrypted using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol.
When a GPU is normally present on a physical workstation, this is a great way to accelerate the performance of these applications on a desktop computer. When you’re using these products in a virtual desktop environment, things change slightly. All of the major virtual desktop solutions (VMware View, Citrix XenDesktop and Microsoft RDVH) enable a software GPU in the virtual desktop session when their VM enlightenment drivers are installed into the virtual desktop image.

20000: The Presentation Server Console contains an incorrect server edition or a license mismatch.
99990: Results when a custom administrator with restricted rights runs the following QFARM commands:QFARM SERVER /APP QFARM /APP QFARM /APP <appname> QFARM /ZONEAPP

Session initialization
No matter how an ICA session is invoked (Program Neighborhood, Web Interface, double-clicking an ICA file, etc.), the ICA client engine (wfica32.exe for Win32 clients) fires up and loads the module.ini file from the root folder of the ICA Client. The module.ini file defines the specific capabilities that the ICA client should or can use. Therefore, when troubleshooting, it’s possible (and useful) to change settings in the module.ini to change the capabilities of the ICA Client.

Very Nice article about IMA by Brian Madden: Remember that a Citrix Presentation Server farm is really just a database (called the IMA Data Store), and Presentation Servers are said to be part of the same farm if they’re sharing the same data store. The data store stores all configuration information for all farm servers. When a Presentation Server starts up (or, more correctly, when the IMA service on a Presentation Server starts up), the following process takes place:
