Hi, Today I set ESXi 7.0 update 3 servers to get an IP address from DHCP server, the host got an IP address, but it didn’t register name with DHCP.

 What is the solution? 

You must open this file in a text editor.

/etc/dhclient-vmk0.conf

Add this line:

send host-name "yourservername";

For Example:

 send host-name "Host-24";

Exit and save the file and reboot the host.

Note: The ; at the end of line is very important, Don’t forget that.

Finish 🙂
