SEPM "Home" page does not relates to PER domain

Hi all,

I have 4 Domains/sites that I manage but each Domain have its own admin to manage their own site.

When one of these admin logs on to their own domain, they see the WHOLE sites of computers, servers, etc and not their own domain/site within the 'Home' tab. I can't find a way to restrist them to see their own domain/site.

Have I missed a settings somewhere to enable this or is there no way of doing this?

Thanks,
