there are hundreds of threads out there and I have come back to restoring my original smb.conf files and then enabled sharing on directories plus changed the workgroup name. I cannot get ay Linux machines to connect to each other or get either XP machine to connect to Linux. Your assistance is appreciated. not that I may not be back until 48 hours from now.

I've made a spreadsheet to make a little more sense of the situation:
