I have two ESXi(5.5) hosts, each with 2-4 virtual guests installed and up and running on them. I just installed vCenter and vSphere WebClient on a separate physical server with no issues, however when I login to the vSphere WebClient, either as a local server admin or a domain admin, all inventory(hosts, datacenters, datastores, etc...) show up empty. There is NOTHING. Do I have to somehow register the ESXi servers with the new vCenter server, or am I missing something else...? Thanks in advance.
