Building a vSphere Home or Learning Lab – Part 2

In Part two, we will install the VMware vSphere Client for Windows, create forward and reverse DNS (which is a prerequisite for installing vCenter in any form) and then we will install the VMware vCenter Server Appliance (VCSA) to manage our ESXi VMs
