We are having an issue were it seems our security servers randomly stop responding and our load balancer (F5) sends an alert out.
When verifying the logs we see the following:

I opened a ticket with VMware and they told me that this is related to old version of the view client and that the only way is upgrading the clients.... Great..... I asked them if there are ways to block old client and they said there is none...
So now I'm trying to find a way of notifying the users with old clients to upgrade.
Being this in a university, we can't control the versions students have installed so what I would like to do is to create a script that somehow will verify their client version and spit out a message asking them to upgrade.
Does anyone know of a way to identify the client version? I check the Volatile Environment and there does not seem to be an entry there..
