I'm having a similar issue. I have a password which meets all the criteria - at least one Uppercase, at least 7 characters, at least one number... I've had this password since June and all has been fine. I used it this morning and it worked. Then the machine locked up and since then my password will not work. It tells me my password is incorrect. I've rebooted the machine to no avail. Also, when I try to reset the password, it tells me "This feature requires removable media, such as a floppy disk or USB flash drive." My IT department tried using a USB flash drive and that didn't work either. Any suggestions??
