Any help is appreciated since I am stumped. I'm connecting two PC's, which are both running XP, to transfer some files between the two. I connected the cable, configured the workgroup and turned off XP's firewall. On PC#1, both computers are recognized in the workgroup, but PC#2 only recognizes PC#2. And when I attempt to PING each computer from the other, PC#2 can ping PC#1 but PC#1 cannot ping PC#2. On both PC's, I have enabled Computer Browsing. Any thoughts on why this is not working? In the past, I have had these two connected with no problems, but now it won't work. Thanks.
