I just upgraded to the latest version 4.3.22 on Ubuntu 14.04 LTS. All my guests are Windows flavors, like XP, 7 and 8.1. All of them are exhibiting the same behavior when it comes to auto-mounted shared folders from the host, they all say "Disconnected Network Drive", but when you open them (in any guest) they work just fine. I did install the latest guest additions that came with this new version. That's the first thing I always do and I do it from the Windows Safe Mode. I also tried removing the auto-shares and adding them back again, but to no avail. Would anyone have any clue what's going on here?

Thanks!

Here's more info for troubleshooting for those interested in helping me out. Thanks!
