Thank you for your response Astalavista! The NAV2002 that I use was inside NIS2002. Things after a while made my internet connection go to bye bye, but when I disable NIS, things go really fine. Right now, I use a different program for firewall. I know that the easiest way is to use the NIS because it is in one package but the firewall from it makes my life harder. Anyway, is there any difference between the NAV2002 and the NAV2005 or 2006 that is coming out? If there're any merits to buying the new one, would some one pls tell me about it?
