Description

When a user inside a published desktop starts a published application, disconnection occurs.

Environment

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Resolution

Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.

Create WSCReconnectModeUser and modify existing registry key WSCReconnectMode in Master Desktop Image or in XenApp Server hosting, the published desktop can change the behavior of the Receiver.

Create the following key :

64-Bit - [HKEY_CURRENT_USER\SOFTWARE\Wow6432Node\Citrix\Dazzle]
32-Bit - [HKEY_CURRENT_USER\SOFTWARE\Citrix\Dazzle]
Name:  WSCReconnectModeUser
Type: REG_SZ
Value data: 0

Modify the following key from the default value of 3 to zero

64-Bit - [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle]
32-Bit - [HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Dazzle]
Name:  WSCReconnectMode
Type: REG_SZ
Value data: 0

Note: Alternatively, the REG_SZ value WSCReconnectAll can also be set to false if creating a brand new key is not preferred.

Problem Cause

The Receiver default behavior is set to the following value: 
3 =  reconnect on application launch or refresh 
When an application is launched within a published desktop it is seen as an open application which generates a disconnection.
