Logon script with company policies

I need a script to run on a NT4 domain that will apply to W9x,NT4,2000 & XP PCs.
I have tested a utility called Winoff which forcibly logs the user off when they select an option. The final script needs to work like this:
user logs on and sees a box come up displaying our companies security policies and email policies. The only options are I AGREE and I DISAGREE
now if they select I DISAGREE it will forcibly log them off.
obviously selecting I AGREE lets them carry on loggin in using Windows.
I did a test with a basic DOS batch file and found a couple problems:
By default the script minimises itself to taskbar.So i added line -Start /max logon.bat- which worked fine, and maximised the whole DOS window, but I would have liked the DOS Windows just to stay same size but come to the foreground, infront of everything else, not maximise.
My boss has asked whether we can get a better looking interface as DOS Windows aren't that pretty.
If anyone can help me with some code in something like vbscript or javascript for the test script below I would be very appreciated.
Also, is it possible for script to run before Windows loads on NT4 domain??
How do I stop the users closing script down and ignoring the question??
