Changing host name on vCentre Appliance

Just a quick one

In my lab environment I use the virtual centre applicance. As it was setup quite quickly i never bothered adding the VCA to my testing domain at initial setup. Needed to test some domain stuff so decided to add it today.

Process is quite simple to add the VCA to the domain

  1. In your Active directory DNS create both a forward and reverse lookup entry for the VCA
  2. Under Networks cofiguration ensure you have the DNS in your AD configured
  3. On the same screen change the hostname of the VCA to the FQDN you have created ( has to be the FQDN rather than just the appliance name. this is in the form : VCA.domainname.tld )
  4. Reboot is required
  5. After Reboot you have to go to the authentication screen and enter the AD credentials and domain name

After doing all of this you will notice that you can no longer log into the vCentre client , you get the following error

vsphere_client

If you are using the built in certs then to fix this issue you have to go to Admin tab and toggle ” regenerate SSL certificate” setting

If you are using 3rd party certs then they need to be updated to reflect the new host name.
