From: Yousuf Khan on 25 Jul 2010 14:17 I have a perplexing problem here. I went on vacation outside of the country, and when I got back my Windows 7 desktop lost almost all of its user login accounts (5 altogether), except for one. The one that isn't lost, cannot be logged into, as the password doesn't get accepted. The machine also has a dual-boot to Windows XP, and choosing to boot into XP gets you the message that that operating system doesn't exist. Going to Safe mode in Windows 7 doesn't help as it doesn't accept the password to the one remain account. Using a Ubuntu Linux, I've taken a look at the Windows file system and all files seem to be still there and I can access them, and Ubuntu doesn't report any physical problems with the boot disk (SMART looks fine). This happened while I was away, so I didn't even observe it myself, and I can't even login to an account to look at the event logs. Yousuf Khan

I would recommend complete sanitization while not connected to a network. Arno -- Arno Wagner, Dr. sc. techn., Dipl.
