I have networked 3 P.C.s at home and mine is the gateway for a cable modem.My problem is that I have to log in and leave my P.C. on for the others to gain internet access.As Zone Alarm was interfering witn the networking,I had to uninstall. This leaves my P.C. unprotected each time it is switched on.Is there any way to allow internet access to the other P.C.s without me having to log in?
