Unable to get a console up running in vsphere client

[OleWilliam]

I have installed the esxi 5.0 on a physical host.

I have on this installed the vMA.

I can not get the console on the vMA up running after starting the vMA virtual machine.

The message in the console window header is:

Unable to connect to the MKS: Failed to connect to server <esxi hostname>:902.

Same problem experienced for the vCenter server Appliance.

After starting the same message appear in the console window header.

Please make sure you don't have a firewall blocking the necessary ports (902, 903)

see http://kb.vmware.com/kb/1012382 for a complete list of ports.
