No Site System Listed in Boundary

[wudevr 0]

Our old SCCM server died.
I removed the old server's objects from the System Management container in AD. 
I've built a new SCCM server. Different Server name and Site Code.
I have enabled and run all the Discovery Methods.
The issue I have is that when I check the properties of the Boundary that is created, the Site Systems tab is empty. 
There is no Site System listed.
How do I correct this?

I created a boundary group, added the boundary to it. Now I can add the site system.
