SCCM Clients not showing update status

I recently ran into an issue at a client site with a new install of SCCM.  We deployed the SCCM agents and out of 1k plus clients, only 12 were showing an update status in the All Software Updates section.  Turns out that post the 1702 build, the Software Update Point Site System needs to be added into the boundary group that the clients are in.  If it is not in there, the clients are not instructed to send their update statuses through their state messages.  Since we had our SUP deployed on a separate server, it bit us.
