Thanks both of you. marian, i use xp as a sharing pc and pclos access uses it good.
but using pclos as a internet sharing pc, i.e. using as a server, it is difficult.
No firewalls here. used Firestarter, with or without it, is the same result. Dad had AVG Firewall in XP (which i hate extremely and very much!) i disabled that too, no use still. It connects, but no net sharing.
mokmeister, you misunderstood me. no bridges needed here.
