samba - Dec 2004 - Sbmclient ( session request failed )

I just found out about this tool and am learning.

I'm running smbclient Version 2.2.5 on a Sun Solaris 2.8 server and want
to send a WinPopup to windows 2000, XP etc. users for different windows
users.

I use the following and receive the following: Do I have to conf
something in smb.conf?

csdev5$ smbclient -M dans.sbc.com -N
