Updating the DNS Search domains and FQDN Hostname for an ESXi Host.

 Here is a quick tip for anyone that has deployed an ESXi host from a home network or received DHCP values that didn't match your intended configuration.


I deployed a machine that I want to use in my home lab, but my default Comcast domain is displayed as the FQDN.
I have already changed this in the DCUI , but it persists in the vSphere client.

The configuration is found on the default TCP/IP stack, Click Networking

Select the TCP/IP Stacks tab

the DNS configuration shows my Domain name as hsd1.fl.comcast.net ,but my proper domain name is in the search domains box. Lets clean this up.

Edit the Default TCP/IP Stack - note the Domain name and Search Domain fields.

Update the Domain name and Search Domains fields to remove and replace the incorrect domain.

Refreshing the host client shows the updated values!


Hope it helps!
