To deploy the vCSA from the ISO image is to mount it to e.g. your local host, start the "installer.exe" from the "\vcsa-ui-installer\win32\" directory, and follow the steps in the wizard.
For the deployment to work properly, make sure that you've created a Host-A. and PTR record for the vCSA on your DNS server(s), i.e. forward, and reverse lookp need to work!
