Port 44334 (TCP and UDP) is used by Kerio Firewall, so assuming that port maps back to persfw.exe there's nothing to worry about :-) For a more advanced port-to-process mapping tool for Windows, try Port Explorer (http://www.diamondcs.com.au/portexplorer/). As well as port-to-process mapping, it also has packet-sniffing, Send/Receive blocking capability, traffic logging, IP-to-country resolving, bandwidth throttling, various network tools (such as Ping, Traceroute, an advanced Whois client, etc), and many more goodies :-) It also solves all the problems identified with other port-to-process mappers so you can say goodbye to blue screens and inaccurate results :-) All feedback is very much appreciated, just drop me an email Best regards, Wayne
