I have an XP SP3 machine connected to network via LAN (rj45) and a Windows7 Home Premium netbook (connects via wi-fi). I want to do simple file sharing. Both machines are in the same workgroup. File-sharing is enabled on both machines. The XP machine can access the Windows7 netbook (W7N) successfully. If I go to the W7N Network and Sharing Center and select "See full map" the XP machine is recognized, but it appears at the bottom of the Results page under the heading, "The following discovered device(s) cannot be placed in the map." Any suggestions for getting the W7N machine to access the XP machine? Thanks.
