Its a bit laborious but for each process shown you can view the sockets it holds, and what port numbers they are on. The display is very helpful identifying the nature of the port as well (ie vt, arpavt, nsstatus). I've requested an enhancement that would present the information in port/socket order but its still 'doable' as is. ---- Jim "seMPEr" Wowchuk Internet: [log in to unmask] Vanguard Computer Services Compu$erve: 100036,106 _--_|\ Post: PO Box 18, North Ryde, NSW 2113 / \ Phone: +61 (2) 888-9688 \.--.__/ <---Sydney NSW Fax: +61 (2) 888-3056 v Australia
