Here is a diagram of my home lab which I have done up. All machines are VMs other than the main ESX server is a physical.

We will start with View 4.6 setup straight away. A few guides that got me to successfully implement my View environment are as below: a step by step installation was helpful http://paulslager.com Kendrick provide me the idea how the event database is configured. http://kendrickcoleman.com/index.php?/Tech-Blog/configurin...
