Use
smbfs instead of samba, then you will actually be able to benefit from samba shares on your Amiga - ie you can mount your PCs shares on your Amiga as regular volumes (an icon will show on WB).
Samba is for the other way - you share your Amigas drives to other computers which can mount them up.
Smbfs is much simpler than samba - it is just a single command. Search for it on amiga.org and you will surely find some examples of how to use it. As an added bonus smbfs is very fast, compared to samba which is dog slow.
