I now have oner server 2003 small business edition with exchange mail server up and running and 5 client pc's. For the moment I'm using mcafee active defense but I'm considering to switch to NOD32. Do you think that's a good idea or is exchange not so well supported by ESET NOD32? Wich prodct(s) would I be needing to secure server and clients? Thanx for your replies!!
