So to summarize:
- You have forward and reverse DNS entries on the local DNS servers specified in the installer wizard (use nslookup to verify from your workstation; not ping)
- You have NTP available locally and the target ESXi host as well as the workstation from which you're launching this installer wizard have their times in sync (do not point vCSA at external NTP)
If these two bullets above are true statements, check that your vCSA ISO download is not incomplete by comparing the hash to the one posted on the my.vmware.com portal. A corrupt download somewhere is know to cause failures.
