Can you restore a backup?
Is it a VM or baremetal install?
There is various software that can crack/reset the password but I don't remember what it's called.
its physic server ..

I have reset the local admin before, but I believe that it does not work on a domain controller.
-
I believe there is a way to do this on a domain controller. I had a friend that passed away and helped his wife gain access to his home network. Unfortunately, I don't remember the exact process since this occurred a number of years ago.

ofc, it only use for rescuing the server. if domain admin dont have full access to this server, also when trust between this server and domain are disconnected..

As far as I know:
- Local admin is disabled on DC.
- Domain admin and people in Administrators group are the only ones that can log into DC's
No local admin until you demote server from DC role

#local admin on dc = did u mean administrator domain?
#DC ( domain controller server) or another server that joined to the domain
#demote = did u mean unjoin server then rejoin? -
When talking about Domain Controllers - it's probably easiest to just think that there is no Local Admin account. It just doesn't exist (can't be used). The only admin (administrator) account on Domain Controllers IS the domain administrator account. Of course the default username of the domain administrator account is administrator.

@shybrsky
Can you paste snapshots of the errors or problems? If you need to past 10 snapshots then do so. What exactly is the "Big issue"? -
I've reset a lost domain administrator account before. Here is what I did.
- Used Offline Password and Registry boot utility, reset the administrator password (This is the Directory Services Restore Mode password)
- Once booted in directory services restore mode I created a script that launched at startup that ran as the system account the script ran the "net user" command to reset the domain administrator password.
- Rebooted the server into normal mode, the script ran when the computer started up and I was able to use the password I set in the script. Then I made sure to remove the script from startup.

- so there is no server\administrator account
You cannot take a DC off the domain without FIRST demoting it.
This is a LAST RESORT.@brianlittlejohn seems to be onto something. Try that next.

I have used this method in the past - it does work, or at least did for me on 2008 (R2)

@brianlittlejohn
I have done this on workstation multiple time and yes it works.
I cannot say the same thing for DC as I have not try it yet. -

#password of administrator domain is normal like other day
#its not administrator domain but local server administrator passwordbefore, i dont need to login as administrator local to gain any access of all my server, but now it different.. force me to set manually administrator domain to be member of rdp user on each server i want to remote.. without administrator local, server said "not authorize"
look like something missing.. some puzzel or goes away..
