Hi! I have a Vcenter 5.1 esxi server that I wish to manage my 2 vmware hosts. If I connect to the hosts directly (192.168.1.116 or .117) with the vsphere client, I get a message that they are being managed by 192.168.1.115 (the vcenter server). But if I log into the vcenter 5.1 server with the vmware web client (as admin@system-domain account), I see nothing, including a "0" for the very Vcenter server I am logged into. From the home screen, If I click into Vcenter, I get the "getting started page". If from the home screen I choose administration, I get a dropdown to choose my vcenter server, and the list is blank. Just a note, this server ran vcenter 5.0 previous to my boss upgrading it. This server was the ESXi 5.0 vcenter server, and the Ip address remained the same. Can someone please help me understand why it can't see itself, and how to register 116 and 117?
