Disabling the AutoSandbox Question

I have an issue with our business application ending up in the AutoSandbox and causing an issue. I know how to disable it on each client and just searched and found out how the change the group setting using the console expert settings but what I am not sure of is if I have to do anything to push those settings out to the clients. Is this automatic? How long does it usually take (I only have about 60 clients running now). I believe it is but just want to confirm.

The avast! clients receive the new rules almost immediately.
