I have just received my 50 users ESET NOD32 Anti virus Business edition user name / password to download the system and deploy on our network. First of all I need to know which product I need to download and install? when I go to the download page it lists many files. Should I start with "ESET NOD32 2.7 for Win NT/2000/XP/2003/Vista (32-bit/64-bit) - LAN Update Server" or any other product? My first goal is to install the AV software to the clients, then to use it for my 1 W2K Server and Exchange Server. Please guide me.
