I can't get to square one. The two computers are connected by a crossover cable, and they can ping each other, but they cannot see each other. Going to Network on the Win7 computer shows that computer only. I do not see the workgroup anyplace. Going to MyNetwork places on the XP machine give no hint of a workgroup or of the Win7 computer. I have now assigned IP (ip4) addresses to each (with one different digit) and 255.255.255.0 to the subnet mask. The IP address of the Win7 computer is now assigned as the default gateway of both. I have read a lot of posts about setting up file sharing and I'm pretty sure I did that right. I ran the network wizard in XP. I'm not trying to use the win7 to win7 option in win7 (homegroup?). But I'm not sure I have the right alternative selected. I do not see where to choose the alternative to homegroup.
thanks in advance.
