In SSMS 2014, when I connect to a server in Object Explorer using my network credentials (I am a domain admin), I can do pretty much everything I would expect as a DBA. But I cannot start/stop/restart services. For instance, if I right-click SQL Server Agent,  the options to Start, Stop, and Restart are greyed out.

Using SSMS 2008R2, from the same client machine using the same credentials connecting to the same server, the options are available and functional when I right-click.

This is true for all servers in our environment.

What do I need to configure in order to be able to manipulate SQL services in SSMS 2014?
