Change Server Name


I was hoping someone can help

I want to change my server name but not sure if I am doing it right?

I logon to my server —Login to the Rcon

I then type into the rcon server.hostname ********* ( this is not the server name just a example )

nothing happens tried with and without a space?

thanks for reading
