Just a basic question/problem

I have everything successfully installed (finally) and can see and discover all my machines.  However, when I try to push the client out to them for management, it fails. 

Are there specific settings that need to be changed or ports that the install goes through?

I am on a Win 2008 r2 server hard wired directly through a switch to my machines (lab environment) which are all win7. 

Any help is appreciated.
