Lately, Microsoft has also changed the way its LAN shares authentication works, and thus if you have a Linux-based Network Attached Storage (NAS) appliance, you might find that suddenly you cannot access shared folders from Vista. The open source camp had to play catch-up and release an update to Samba that implements Microsoft´s changes. But of course, not all hardware vendors have released updates to their NAS firmware, and if you have a NAS unit no longer supported by its vendor, then too bad. The result? The Vista users sees there's "a problem" with the NAS units... and blames the units, not Microsoft for changing the way authentication works, and faced with the choice of having to dump Vista or replace the NAS, they might end up choosing the latter.
