Citrix Registry Hack and Configuration files

Regystry Keys

ICM pings are sent if network traffic is not detected. When a user employs an application that makes constant screen updates, 

ICM pings are not sent. In this instance, a broken network connection causes the session to wait on the TCP time-out. 

When the TCP connection times out, the session goes into a disconnected state(Grace Period). 

This change generates ICM pings on the network connection at the configured rate that is independent of the data sent by the application.

In the registry there's a value called "HonorZPFOverSessionSharing"
\HKLM\SOFTWARE\Citrix\IMA\MFRPC key

The default value of "1" means that zone preference will take priority. Change this to "0" if you always want users to open new applications within their existing sessions.
