Policies and tasks are delivered as part of a normal agent / server communication, so if the machines cn communicate with ePO, they should be receiving policies. I would check that the machines have the policy assigned that you expect them to, and that there are no policy assignment rules that could be overriding this.
Are policies for all products affected, or just a subset?
In ePo, when I view policies assigned to PC, it shows Agent policies which I have assigned to an OU.
Where on client side can I check which policies have been assigned ?
At first it seems that client gets agent policy, but not tasks assigned to OU ?
For some odd reason, it started to work. External clients are gettings tasks aswell now. Why ? Unfortunetaly no clue.
Unfortunately at the client end you can only confirm the policy applied by observing the effects - so if you have a policy that sets a specific agent-to-server communication interval, you can apply this policy and then check in the agent monitor that it's been applied. The actual policy files themselves on the client machines are encrypted and only Support can read them. (It's one of the first things that is done when it appears that policies are not applying.)
Try making a simple change to a policy assigned to a machine, and then apply the policy and check on the client that it's applied. If it is, then at least we know that policies are being enforced correctly.
