I have setup an ESXi lab with in a physical host, hosting two nested ESXi hosts. All this hosts are version 5.1
I have created a Windows server 2012 R2 virtual machine (which I promoted to DC) at the physical host level and another Windows server 2012 R2 to install vcenter server. I have joined this machine to the domain.
I had to install the vcenter server in the Windows server 2012 R2 utilizing the media for version 6 because I can't find the media for the vcenter server for 5.1. The installation was successful and now I am trying access the vcenter server using vsphere client from my computer as I accessed all host directly but I am getting the attached error when trying to sign in.
What could be happening? Any help is greatly appreciated!
