Hello there, I've read an earlier post about Inventor 2009 and NOD32 where the solution was to go to http --> Web browsers and check everything saying "autocad": https://www.wilderssecurity.com/showthread.php?p=1329391 It doesn't help me though. I need for users to connect to "Content Center" through a "Vault" server. If i have NOD32 enabled i can't connect. It stalls for about 5 min and then nothing happens. If i disable webaccess protection it works fine but it's not a preferred solution. I've tried to add the server ip under "Excluded addresses" but that makes no difference. I'm not sure where to go now?
