Can't create new build definition in TFS 2010

When I start create my first build definition for Team project I face the following error:

TF225001: Creating a build definition requires a build controller be defined for this team project collection. 
There may not be any controller configured or you may not have permission to view them.

So after little search I figure it out it will be as the following

 

So now if you create a new build definition you should see the following screen

but the problem that I didn't choose network service so I have the following error \"Cannot start service TFSBuildServiceHost on computer\" and after good search on event log I found that this because failure of the login so I change it to be a network service as the previous configuration.
