on a Windows client, to be sure you're happy with the change, and to re-test that short name lookups such as ping vcsa
(or some other home networked device with a DHCP reservation) functions.The recommendation is to use the FQDN.
Ensure that DNS reverse lookup returns an FQDN when queried with the IP address of the host machine on which vCenter Server is installed. When you install or upgrade vCenter Server, the installation or upgrade of the Web server component that supports the vSphere Web Client fails if the installer cannot look up the fully qualified domain name of the vCenter Server host machine from its IP address. Reverse lookup is implemented using PTR records.
If you plan to use an FQDN for the virtual machine or physical server, you must verify that the FQDN is resolvable.
