On Policy Manager I have the policy set for clients to check for updates every 30 minutes. However on the clients they all update once and usually all to the same version and then don't update again until the following day.
For example right now Policy Manager shows it has Version 2017-02-17_17 and all clients have 2017-02-17_03
Has anyone else seen behavior like this? PM Server is 12.31 and clients are 12.30 and 11.61 mixed (v11.x on XP stations)
