Comment 48 for bug 529714

Ok I have been messing around with 10.04 in virtualbox, ubuntu sees windows shares easily without winbind even being installed and without adding wins to nsswitch.conf, and once samba is installed my windows box can see ubuntu without any problems, also rhythmbox is working fine.

so it seems something is breaking the way samba looks at the network, if winbind isn't even needed there's no point trying to fix that.

I'd try putting samba back to how it was on first install but I don't know how and I don't want to cabbage my laptop, If anyone knows how to do it safely I might give it a go though, I thought I could just delete a bunch of files in /home/username/ but there's no .samba or anything that looks like a home for samba config files.
