If it is on the domain you should be able to go onto Active Directory Users and Computer using RSAT or your domain controller and just reset the Domain Admin password from there.

I do not have the DA pwd and cannot login to the server. Sorry if I was not clear

Thank you MAS, I used that method to change the HOST password, (host has windows server 2008 R2) I am trying to gain access to the Server installed on Virtual Machines (SBS 2011)...How can I reset the password on a server in a VM?

The same will work for VMs in the host

The below method works fine in Virtual machines.

Boot from the Micrsoft Windows Server 2008 DVD
From the Install Windows menu, click “Next”.
Select “Repair your computer”
In the System Recovery Options, select the Operating System instance that you wish to repair and click “Next”.
Select “Command Prompt”. The
At the command prompt, run the following commands:
c:
cd windows\system32
ren Utilman.exe Utilman.exe.old
copy cmd.exe Utilman.exe


Reboot the server allowing Windows to load as normal
At the logon screen, press Windows Key + U.
As the command prompt, enter the following command:
net user administrator Password12
This will set the password for the Administrator user to be Password12 (case sensitive).

Closing the command prompt, you should now be able to log back onto the server using the password you have provided in the last step.
