I don't agree with your comment Chow Loong Jin. Before ubuntu 8.10 we have a tool, installed by default in gnome, to let user change his workgroup. Since nautilus-share is the default tool to share by samba, and since the tool to set workgroup have been removed, this is a bug (very minor -> whishlist, but a bug), assigned to nautilus-share. Nautilus-share should be patched to add the possibility to let user set the workgroup name.
