Where has access to windows workgroups gone?

[Robert McBroom]

caja, dolphin, konqueror, thunar and nautilus all fail to connect to the 
windows systems on the local network.  I can connect with smbclient and 
cifs in a terminal but that doesn't allow the full capability of click 
and drag to move files and examine them.

Is athere something I am missing tahat will restore the functionality?
