Salut!
Nu-ti trebuie cont...mergi in control panel/panou de control-network and sharing/retea si partajare (windows 7)sau network connections/conexiuni la retea (win XP)-click dreapta pe adaptorul de retea-properties/proprietati (sau change adapter settings/modifica setari adaptor win7)-cauta ip adress (atentie, la win 7 cauti ip adress v4, nu v6) properties, si pune pe automat atat ip adress cat si dns servers.
Bafta!
