How to Change Your Mac OS X (Snow Leopard) Computer Name?

ORIGINAL : http://www.dbuggr.com/yakimeshi/change-os-snow-leopard-computer/

1. 

Apple menu > System Preferences > Advanced Network > WINS tab

Specify WINS NetBIOS Name and Workgroup names.

2.

Apple menu > “System Preferences” > “Sharing”.

Type in the new Mac computer name in the “Computer Name” text field at the top of the window. If sharing is turned on the text describing the type of sharing should reflect your newly changed name.

3.

Open the “Terminal” application and enter in the command:

sudo scutil –set HostName [NewMacComputerName]

4.

Next flush the DNS cache on the Mac by entering the command:
dscacheutil -flushcache

5.

Finally reboot the Mac and if your home router provides DNS services like mine does reboot that as well.
