Windows Server 2008R2 Domain Admin Password lost and cannot reset it.

Admin password has been lost.
Have used a program called Windows Password Recovery Tool which does actually reset the "Administrator" password in the AD.  This works fine on a server with Administrator as the Admin account but not on 2008R2 which by default disables the Administrator account.

The Util does not work with any other user other than Administrator.

I have looked through EE for a fix but all options point to DSRM and I cannot get the DSRM to show up by pressing F8.  When I get a boot menu I only get Safemodes or Normal as an option.

Utlimately the production AD Server is SBS2008R2 and I am just testing the theory before looking at the SBS2008R2 installation.

The Windows 2008 Server must be a Domain Controller to be able to run DSRM.

Check http://www.petri.co.il/reset_domain_admin_password_in_windows_server_2008_ad.htm 
Change the  administrator reg name in what you are using for administrator.

I cannot get DSRM to show up as an option as in the article for 2003?

It is a Domain controller on my test VM.
The eventual target server is SBS 2008R2 - will that have an DSRM option with F8?
