start service when get login prompt

Hi Team,

I am using DRBL environment on Ubuntu. When my machine starts some times it's not starting lxdm & nslcd service. Because of that i didn't get graphic mode & also not able to authenticate user as nslcd is also stops. I have to login as root and restart these two services, then i am able to start my work.

Is there any way so that i can set these two services restart when booting?
