Administrator password hacked on Windows 2003 SBS

The Administrator password on a Windows 2003 SBS running Exchange no longer works. I believe the server was hacked. I tried booting from Password Recovery disc and RESET the password to nothing but that did not work either. IBM Server running RAID1. How do I get back into the server or recover the lost or changed password? Redoing server is not an option since there are over 250 exchange accounts.

As SBS uses domain accounts, can you access the domain?
As long as you can access the domain, you can reset the admin password via AD. But this assumes, that you can logon as a domain admin, otherwise you will not have permissions to change it.

Do you have any other Domain Admin accounts configured on the domain?

If you do you can login as that account and reset the administrator password using:

net user administrator newpassword /domain

There are paid tools out their that let you boot to a CD/DVD and blank out the domain administrator password.

Video and blog post about using one of these tools.

You can probably find free tools out there as well.

I was able to create a BOOT disc from here: http://pogostick.net/~pnh/ntpasswd/

And then reset the password to blank. I am in now.

What may be a reason - as it is very common - possibly was a knock out. If the admin account is also used for services or applications. it can just be knocked out by to much wrong logons.
i.e. Sharepoint has an option, to change the passwords automatically.

I would first create a second domain admin you can use for logon. Then search for the reason, why the original admin changes its password. As Sharepoint is also part of SBS, I would assume something in this direction. Search the security log for failed logons of the admin, see when it starts and which application / machine / whatever tried to logon shortly gefore it stopped working.
