Logon prompt to accept policies

Hi,

At my place of work, we would like to implement something at Logon to where users’ consent for proper use of informational assets and security & confidentiality policies. We have to main entry points, NT/W2K and Novell. There will be an accept or not accept answers returned.

Could this be done through login scripts for NT/W2K/Novell or only through a third party software.

Thks,Vinh
