Pull Dp concept

When a package is distributed to a PullDP, DistMgr creates a PkgXferMgr job and added to the queue.- PkgXferMgr processes the job and creates a PullDP notification in the PullDPs WMI.- PullDP reads the notification and starts the download from a assigned Standard DP based on priority.- Once the notification is written, PkgXferMgr monitors the job for next 10 hours (max value hardcoded). Every 60 mins.- If the status is not received from the PullDP, it will mark the distribution as Failed and it creates a Status Message and DistMgr processes the message.- if a package is successfully downloaded in the PullDP, even after it exceeds the 10 hours, it will send the status to MP and it will drop a file in Distmgr.box.- DistMgr will check the existing status in the PkgStatus table.- Since the PkgXferMgr already dropped a failed status, it will ignore the status which has been sent by PullDP.- So the status will stay as failed. But content is distributed. However clients won’t work due to status marked as failed in Database.-  It is by design in CM12 R2.- Above hardcoded values can be changed in ConfigMgr 2012 R2 SP1 using AdminUI.
