SCCM 2012 Subnet Boundaries. IDs and Subnet Masks: Thank YOU, Jason Sandys.

Recently, in my new SCCM 2012 environment a couple of W7 laptops started to display a worrying issue. The Config Manager client was not showing all the tabs, nor were there enough Policies and all the Components were listed as Installed but the necessary ones weren't enabled.

Every search on Google came back with Boundary (and Boundary Group) issues yet my logs (ClientLocation and and LocationServices) seemed to be saying all was well. Clearly something was wrong. It was late, I was stressed and worried. Then after many 'wrong links' I finally landed on the Oracle's page. He that shall be known as Jason Sandys. In one of his posts he talks about the Evil of Subnet IDs. In short the issues described in the post are exactly the issues I am facing: VLSM and thus overlapping boundaries.

So, without further ado, head on over to this post and drink your fill.

If you are suffering from strangeness with the client and resetting, re-installing or other fixes aren't working then you may well be in the same boat.
