"Someone from 188.8.131.52, port 2557 wants to connect to port 135 owned by 'Distributed COM Services' on your computer" I just installed Kerio 2.1.5 and on dial-up I get this type of messages popping up every minute. IP numbers change every time. Is this normal or someone is really trying to connect to my computer?. The IPs are mainly from my provider's domain. Should I block these requests?? I permitted a couple of times and nothing happened. Win98 - KAV 4.5 Before I had Kaspersky Anti Hacker and I did not get any of these messages. I appreciate any help. Thanks..
