In some environments, administrators may want to prevent end users from copying and pasting between their vDesktop and their thick or thin client. The proper way to prevent the copy and paste functions is via the group policy of the vDesktops.
This is defined in the PCOIP.ADM template available on any View Connection Server in the \extras subdirectory. This setting can be found in Computer Configuration\Admin Templates\PCoIP Session Variables\Not Overridable Admin Settings\Configure PCoIP Virtual Channels.
Within this setting, there is an allowed and disallowed list. If a virtual channel is listed on both the allowed and disallowed list, it will be disallowed. In View 4.6 and later, the virtual channel responsible for the clipboard (mksvchan) no longer needs to be explicitly mentioned. Instead, the administrator can simply check the disable clipboard processing on the PCoIP host and enable the policy.
