Intermittent problems launching Controller via Citrix, caused by disconnected sessions, triggered by third-party program (for example Symantec)

Troubleshooting


Problem

Customer is deploying Controller via Citrix. Specifically, they have created a Citrix published application which launches the client executable (CCR.EXE). Intermittently, users find that they cannot launch Controller. During troubleshooting, the I.T. department find that these 'bad' users have a 'disconnected' session on the Citrix server. If they manually logoff that Windows session, then the 'bad' user can then successfully launch Controller. What is causing these 'disconnected' sessions, which stop users from launching Controller in the future?

Symptom

User clicks on the Controller icon (inside the Citrix StoreFront website), and the application launch process appears to start OK, for example:

However, afterwards the Controller client application never appears.

Some other symptoms will occur (which vary depending on environment). Some examples are:



(1) Cannot start app "Controller"


(2) If the user right-clicks on the black 'Citrix' icon, and chooses 'Connection Center'...

...then there is no server name under 'Active'
- In other words, the Citrix client does not think that the Windows user has an active Citrix session (despite the fact that there are several processes running on the Citrix server, running under the user's Windows logon name)
