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??

Hi JM, Thank you for your post. If the account is a domain user, try to use this account logon another server, then reset the password. If the account is a local user, try to use another account logon server to reset the password or boot server with WINPE CD to reset the password. If there are more inquiries on this issue, please feel free to let us know.Regards, Rick Tan

Reset a domain password is complex than the local one, you can see this informative tutorial about how to reset windows server domain password.
