I can’t find anything about it in Google and I don’t have time right now to pursue the matter, but my new Vista installation steadfastly refuses to talk to my file server, running Samba on a Linux machine. I can try to connect to the share and I’m asked for my authentication, but Vista doesn’t like my username/password combination, no matter what I do. I did manage to connect to a Windows XP machine, so I guess they just killed the protocol once again…
