Due to the number of agents we have this becomes a bit of a nightmare to try and push the latest update to the client machines. Due to this I worked out what the script number was that ran when this was scheduled then using views in the system I push updates if it's not at the latest version.
Truth be told that I only bother with servers at the moment and try and pick off workstations when I have the time (rarely) but it works well.
I'd post the procedure but don't want the wrath of Brendan :+) as if Kaseya wanted us to be able to do it that way I'm sure they'd make it more accessible.
