Windows – Resetting administrator password on Windows server 2008 R2 over Raid

password-recoverypassword-resetraidwindowswindows-server-2008-r2

I have locked both my administrator accounts out on my Windows Server 2008 R2 that has Raid. I tried the following-

  • Insert the original Windows Server 2008 installation DVD
  • Reset the computer, boot from DVD
  • Choose option “Repair your computer”
  • Start command prompt
  • C:
  • CD C:\Windows\System32
  • MOVE Utilman.exe Utilman.exe.bak
  • COPY Cmd.exe Utilman.exe
  • You may also need to “Enable” the administrator account which can be done by using NET USER administrator /active:yes
  • Restart Windows
  • At the login screen, type Windows+U; this fires up cmd.exe now
  • NET USER administrator newAdminPasswdHere Presto! Login as administrator!
  • Now repair computer again and move the original Utilman.exe back

My problem is that since my server is on Raid when I am at the command prompt from the dvd the cmd prompt does not recognized the c drive.. it says "the system cannot find the drive specified."

Does anyone know how to get it to find the C: drive, or any other way I can get into my admin account?

I always use Windows Password Resetter to do stuff like this. It works well enough to blank the Adminstrator password (allowing you to reset it on next login). The bootable Live CD can usually see most drives I deal with (provided I am using real, bona-fide hardware RAID).

Haven't had to try it on Win7/2008R2 yet, though -- might be some restrictions built into those operating systems regarding logging in with blank passwords.
