Server task to a dynamic group

[Phydeauxdawg 5]

I have two dynamic groups, one that has old agents and one that has old anti-virus. It simply queries the installed versions and returns those computers not matching a certain version. I have a task that executes each time a client joins the dynamic group for old antivirus, but I can't assign a server task to a dynamic group for the old agents task. How do I accomplish this? The new computers  show due to the active directory sync. I am trying to make the process as automated as possible.

Membership in dynamic groups is evaluated by agent on clients. If agent is not installed yet, the computer cannot join a dynamic group. If you intend to upgrade agent on clients, you can assign a client task "Remote Administrator Components Upgrade" to a dynamic group.
