Dear Habdin,
sorry, I am so new, but where can I find Nautilus

Best regards,

to Nautilus just double click home in gnome
(It seems that you are using KDE may God help you)
again and again I love gnome and suggest using it
-are you asking this about the samba server if so I think konuerer will help too-
or open a terminal and type
nautilus &
don't bother your self to know the spelling just type na then press tab (or tab tab)

Salamo 3alaikom,

Beside this method mentioned by ErrorMsg, In Redhat there a direct link that initiates Nautilus with the smb location direct into it. You can find that link in the menu directly and is called Network servers. Second, You can go to Nautilus via the Desktop as the Home icon when clicked will lead you to Nautilus in Gnome or Konqueror in KDE. Both allow you to browse the network.

Salam.
