I give the registry entry, DisableRogueDetection to 1, a try because I don't think a packet filter will do any good (I tried it and my FW service was crashing almost immediately). The server is running now for 15 minutes and so far so good. I hope this will be the solution. I'll let you know if the log is staying clean! For now I want to thank you all for the support. Greetings, Leo
