I have samba server with smb_server as the name.

Output of "smbclient -L smb_server -U%" is:
==========================================
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.6]

        Sharename       Type      Comment
        ---------       ----      -------
        IPC$            IPC       IPC Service (Samba Server)

        ---------            -------

But when I try to browse from dolphin in KDE it says:

"Unable to find any workgroups in your local network. This might be caused by an enabled firewall."

Can someone help me with this. I have searched on google for one hour now but no avail.
