This is just another way to do it: an adware/spyware free /etc/hosts for your laptop or home network.
On Windows XP if you are not joined to a domain there will be no
Securitytab option available.
Today I was in such an hurry to remotely connect via Remote Desktop Protocol to a Windows host in my network. For things like that, I used to stick with Remmina (GTK+ remote desktop client).
