How to change IIS WebServer Name using powershell

Hi all

Last week I cloned 40 IIS WebServers (W2K16) from VMWARE VM with newSid generation in order to swap old IIS Webservers (W2K8).

All new servers have correct netbios and hostname, but in IIS console the "name server" that appears is the name from orignal VM that I used to clone.

So I look for powershell CMDlet to rename IIS name server.

Also I if you know any other settings in IIS that should be renamed / modified all your feedback shall be welcome.

Thank you for your help
