Hi Natster,
Any task you run (even a config refresh) will update the client to the version of the server. To check the version of the client, open the client properties window under the 'Client' tab. And, yes, if your clients are disconnected from the console you cannot run a task. To help me investigate this problem, can you give me more details about your scenario? Were the clients connected with the console, then you updated the console (since the version is different) and they showed disconnected? What is the version of the console and what version is displayed in client properties? Please describe the steps you used.
Adina
