I only have a single site. Instead of setting each boundary group to assign a site, what's the best way to assign all clients to a single site?
Based on the clients you can use single boundary group .
I have 4000 Client i created below in single boundary /group . Subnet based discovery and created collections .Now i split task for each collection and easy to manage .
Client - 2
2000+ client in 4 different locations
I use primary server and created different boundary group and Installed Distribution point/Group each client location .
