The HTTP mirror server doesn't work well in my environment. I want to hand these updates out over IIS. I have my Nod 32 2.7 clients updating fine from IIS, however I can't seem to get my 3.0 clients updating from IIS. I've followed the changes in this post; http://www.wilderssecurity.com/showthread.php?t=194245&page=2&highlight=update.ver But I can't get that to work either. In Wireshark I see Nod 3.0 download the update.ver. It then says no update available in Egui.exe, though there clearly is. If I go to a browser and do http://servername:2221/update.ver it displays in the browser. If I go to :8081/update.ver (IIS) then it prompts for a download. I'm guessing this has something to do with the problem. How does get Nod32 3.x to update from IIS? If this requires Apache, I can load the Apache service up too, that is an option. Thanks!
