DC Looks to be hacked!

I cannot login to Hyper-V host or any of the V- Servers via my normal AD Administrator Login. I'mm the one and only admin and client to my domain.
It has been several days since I attempted a login.
What is the procedure for resetting the admin lofin?

Something smells fishy here.

Who hosts your host?  Can you not log in via Directory Services Recovery Mode?  Is there only one user account in the whole domain?  

You can always restore from backup...

Is your DC a VM?  Do you have any 2003 DC's in your domain?  What is the error you get?  Are you able to access your server after you restart it?

Who host my host?
Physical server is Hyper-V host and the server is sitting on the rack in front of me. Pretty much one user but you did remind me of another.

paulmacd thank you for reminding me of my backup account. It logged me in and allowed me to reset admin password.
I then  did a gpupdate /force and its starting to aloow me access to my other VMs.

I still have no idea how this could have changed
