If the computer is a member of a domain - as it is in your case, policy
retrieval happens when the system starts or at the defined IPSec policy
polling interval(default 180 minutes) AD Policy.
If you manually stop and start Policy Agent - i.e. net stop policyagent
and net start policyagent - it should read the policy and apply it
immediately.
