Your fedore core has built in Samba 3 which is Cool
Just open a console type ntsysv and select smb there.
This is for starting samba as linux starts
Also type
service smb start
to start your samba server.The default config will do.
Then browse the network from Linux Pc as if from a windows PC.
Also you can use
http://<yourip>:903 in your linux browser
for graphical administration of samba
Cheers

Note:Just to transfer files use ws-ftp in windows.[download it its a freeware]
