This is a test environment. I have ESXi installed and created a couple of VM's. I was able to get to the console without any issues. I then installed VCenter and added my ESXi server to it. I have 3 Vm's (2008r2-Vcenter server, Win2012R2, and ESXi). The 2008r2 VM when I go to the console I get Unable to connect to MKS - internal error. However if I load the 2012 server the console works fine. I have both Vcenter and ESXi in DNS. I even created a host file on the machine for both. Not sure what I am doing wrong. Any help is appreciated.
