How do I install the unix extensions samba?

Download the Samba package and unzip it. Locate the path that Samba is unzipped to, and the double click the smbsetup.cmd. When your command prompt window closes, indicating that your installation has completed, double click on the cygsetup.cmd. Restart the server. Since this is very much technically adding one third party server role, restarting your server which allows the services and the protocols to just start as cleanly as it is possible. In this case, the Cygnus and the SMB services will then start. Return to the Samba directory and then double click on the start_daemons.cmd option. Open the command prompt and then type the smbclient -L localhost -U guest%password option verbatim. You should then be given information about your active Samba fileserver, indicating that it is now totally working.
