I have (3) Windows-2003-Servers. That is all that I need NOD32 Anti-Virus for. I have read that the 5-Bundle NOD32 Business is good for 1 Server, and 4 Workstations. I have also read that you can't buy less than 5 licenses. How can I buy 3 licenses for NOD32 for (3) Windows-2003-Server? I've tried contacting ESET on the phone, but I've never gotten through.
