Set up Windows XP disclaimer screen?

[gotnho]

I'm trying to set up some disclaimer like screen for computers on business network. What i'm looking for is just a screen that pop up some where in the loggin in process, before or after, that just say like "This is company properties blah blah blah .....". Curretnly i have no idea how to implement this so if some one can help me out that would be awesome. Thanks.
