Seems to work with later versions of Server - 2003 and 2008 confirmed
Reset local admin password - use something like Offline NT Password Recover Boot Disk
Press F8 and boot into Directory Service Restore Mode, log in as Local Admin
Install SRVANY and INSTRV to a temp folder
srvany.zip
At a Command prompt, point to the directory you saved SRVANY, Type:
instsrv PassRecovery "d:\temp\srvany.exe"
<-Modify path as appropriate
Start RegEdit and navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\PassRecovery
Create a new subkey called Parameters and add two new values:
name: Application
type: REG_SZ (string)
value: d:\temp\cmd.exe
name: AppParameters
type: REG_SZ (string)
value: /k net user administrator 123456 /domain
Replace with appropriate path and the password you want to implement
Keep in my mind that the default domain policy require complex passwords (including digits, respecting a minimal length etc) so unless you’ve changed the default domain policy use a complex password such as P@ssw0rd
Open Services.MSC and open the PassRecovery property tab, make the starting mode Automatic
Go to the Log On tab and enable the option Allow Service to Interact with the Desktop
Log on with the Administrators account and the password set in Step 6
Use this command prompt to uninstall SRVANY:
net stop PassRecovery
sc delete PassRecovery
