If your Windows box cannot find the samba of your redhat, you have to reconfigure it.
The central configuration file for samba is
/etc/samba/smb.conf
You can use Webmin to administrate your Samba on RedHat
just search for sama tutorial or howto in google 
another (faster and more stable) way is to install an nfs client (linux networking) on your windows, and share via nfs-server folders from.
For this you need nfs-user-server or nfs-kernel-server installed on your RehHat Box
then you can share a folder by adding a line like this in your /etc/exports file
/folder/you/want/share IP(rechte)
i.e.
/home/myself 192.168.0.0/255.255.255.0(rw,sync)
or
/home/myself 192.168.0.3(rw,sync)
then you have to restart your nfs-server
/etc/init.d/nfs-user-server restart
i have wrote a (german) howto about NFS here
