Problem to publish the project

Hi,
I created one more site below like for deploying VS 2012 projects
http://dl.dropbox.com/u/40211031/t409.png

and then deploy the project using these
Service url: http://vs2012
Site/application: vs2012/Start

but I then get this error. Why?
Error    1    Web deployment task failed. (Could not connect to the remote computer ("vs2012"). On the remote computer, make sure that Web Deploy is installed and that the required process ("Web Deployment Agent Service") is started.  Learn more at: http://go.microsoft.com/fwlink/?LinkId=221672#ERROR_DESTINATION_NOT_REACHABLE.)       0    0    Start
