Anyone know which processes usually use port 1112? Just tried to use 3com's Network Supervisor and it reported that it was held open by another process... netstat said that it was the firewall client but I couldn't tell "who" the firewall client was holding it for. Ideas anyone? I know there's a util to find out which process\app is using a particular port but I can't remember it right now!! Paul Stratford, Systems Manager PI Global/PI Design
