reset HP iLO 3 Password

Someone in the office played me a trick, and configured an iLO configuration password. (Maybe it was me in a very weak moment, but of course I would never admit it.) Anyway, I was unable to configure the iLO and needed to reset it. Turns out, this is quite easy.
The following steps are necessary:

  • remove server from the rack and open the case.
  • locate system switches (Jumpers) (see Picture)
  • set the iLO security switch to ON (ON = security off, OFF = security on) (see red arrow on picture)
  • start the server and press F8 to enter iLO config menu
  • you will still be prompted for a password, but any will be accepted
  • set a new password, reboot and revert jumper settings

good luck!

Reset Windows Administrator Password

This should work with Windows Vista, 7, 2003 and 2008, maybe more. I personally tested it with 2008 R2 Standard only.

To reset a Windows Admin password, you need the following things:

  • Physical access to the Server
  • A Windows installation boot media

If you have it all, continue with this:

  • insert boot media and reboot (from media)
  • jump through the menu so that you get a recovery console at the end
  • find the original installations C:\ drive and change to it (original C:\ drive can be D:\ or any other letter when booted from recovery/install media)
  • then:
cd Windows\System32\
copy sethc.exe C:\ <-- remember: C:\ could be D:\ now!!
copy /y cmd.exe sethc.exe
exit
  • reboot your box
  • on login screen, press shift-key five times
  • a command window should show up
  • maybe you have to press Alt+Tab until the new window has the focus
  • type:
net user administrator <new password>  <-- while <new password> is  actually replaced by your new password :)
exit
  • login with your new password
