Well, the problem is that i can't access to my network, i mean to the shared resources in a Win PC

p.s: i established in samba my work group correctly but nothing happened.

You don't really need the full samba monty for that.
samba-client is enough, and no configuration is needed. Just open konqueror and type in the addy bar "smb:/"
There are also samba automounting tools like smb4k, or (my favorite, since it works with any desktop, not just kde) smbnetfs.

thanks.

p.s: i misspelled, i mean smb4k not S4mb4

p.s2: doing smb://CLIENT_WITH_WINDOWS_IP/ should work without any config needed right ?

Usually one's typing "smb://WINDOWS_HOSTNAME" and not the windows box IP, although typing "smb://192.168.XXX.XXX" instead should also work.
Notice that the "smb://" thing is part of the KDE virtual filesystem, and will only work with KDE apps (konqueror, krusader, dolphin...).
