Like mentioned earlier, it seems that the "failed to retrieve shares list from server" problem may me related to the lack of samba package on an out of the box Ubuntu installation. Having the samba package installed appears to fix the problem or, at least, in more complex situation, be one of the steps involved in fixing it. See the default package listing fro 12.04 where there is no samba package, while other related samba package are present: http://releases.ubuntu.com/natty/ubuntu-11.04-desktop-i386.manifest
