k. k. after a long time i'm here to ask a question. Well, i put my Desktop Computer and my Laptop on a LAN My Laptop has Windows VISTA running and my desktop computer has Windows XP SP2 running. For XP & VISTA, i've set the static IP's to 192.168.1.1 and 192.168.1.2 respectively. Now i do a ping from XP to VISTA and XP receives the reply But, when i ping from VISTA to XP, i get no reply whatsoever. So now, i stop & disable my firewall service from Services.msc in XP. Now i do one more ping from VISTA to XP and i get obviously get the reply. . BUT, what my problem is, is very specific. Can anyone tell me what [in the Windows XP SP2 firewall settings] was actually blocking VISTA from pinging XP? Cauz i don't really want to disable my windows firewall, i will just put the above reason into the exception list of the firewall so i can ping from VISTA as well as have a live firewall for my Windows XP SP2.
