tank u for helping me ... but i think it won't work, ..."where "appname" is the .exe name of the application that is hanging" it's because of the firewall i think, however the frozen application is not the firewall, but the prog that wants to reach the net [first time, no rules defined yet] ... i've tried almost all firewalls ... but all makes the computer died [shorter or longer time], maybe i've denied an important win prg to access the net ? maybe wrong win-network-settings ? [dhcp, behind router, dinamic-ip, pppoe] do it have any sense to do a memory dump of the sysem after the "hanging" is over ? [during the slow-down i can't do anything ...] all drivers are new or almost new, factory drivers ... except "nvidia integrated firewall", that one isn't installed, so it shouldn't "work", can cause a non-installed prog fault ?
