Here is what I have, please correct if needed.
Computer 1
System prefs->sharing->Personal File Sharing On
Put file(s) into Finder->HomeDirectory->Public to share
Computer 2
System prefs->sharing->personal file sharing on (is this necessary?)
Search for him via Finder->Network->Browse for the name of his/her computer
Click on it->Go->Connect to Server
then server is 192.168.0.101 and press OK.
then drag and drop files as needed.
sounds like there is something wrong with this.
