I have Q170 Intel chipset and was able to use remote control through AMT capabilities. It has been working for just a few months and then stopped. I got the message "Either the user name was not recognised, or the password was incorrect". I didn't forget password. I was able to use "incorrect" password to open AMT bios properties. I just turned off AMT in BIOS and turned it on again. Remote control function was returned back and I was able to use it during the next few months but I lost control and now I have the message about incorrect password again. I beleive I can use the same way to restore control as I've got permanent work. Can someone explain me what has happened and how to fix it? I've bios updated through the latest vendor software
