I'm looking for a scripting command which would force all machines in a given group to synchronize with the server. In the scripting guide, I see the command "ForceSync", but it appears that "ForceSync" needs to be run from the client you want to sync. Is there an overload for this command that the guide doesn't talk about which takes more parameters? Am I looking at the wrong command? Is this just not possible?
Just not possible I'm afraid - force sync from EEM is a function of the application itself, it can't be done with the API.
You could restart the Client Manager service on the machines - that would give you the same effect - I can't see why that would not work but it could be nasty - make sure you stop it cleanly and nicely if you go down that route.
