HI Freinds, I want to display a policy page during logon to all users,i want to do this via group policy is it possible via GPO if yes how do i do it Thanks Kumar.

To display a html page with this message, you can do using a script. But if you want display a message popup the way is Computer Configuration\ Windows Settings\ Local Policies/Security Options Policy: Interactive logon: Message text for users attempting to log on AND Interactive logon: Messagetitle for users attempting to log on
