I have a rather unique issue, and was wondering if there's a simple solution to this that I am failing to find.

I have a Windows Server 2012 instance running remotely, that I have no physical access to. As of yesterday morning I had full control of it via RDP and via FTP.

Yesterday evening I removed Active Directory services and such demoted the domain controller. During this process I changed the password and made a note of the changed password.

Now the server is rebooted, I cannot get access via RDP. I just get a bad credentials error response.

I still have root FTP access, however, is there some way I can regain RDP access using only FTP?



Filler words for length restriction.

  • Is there a way I can change the domain RDP tries to connect to? It defaults to AD\Administrator, but obviously with AD disabled that is not going to work. – James Legg Nov 27 '18 at 10:44
  • Have you tried to connect to the local administrator, e.g. DC\Administrator where DC is the server name or just plain Administrator? – Sven Nov 27 '18 at 10:45
  • Yes, but with me having demoted a domain controller yesterday I think that may have had an adverse effect. I can still see all of the users via ftp, and all of the services are still running. – James Legg Nov 27 '18 at 10:49

    Welcome to serverfault. Your post may answer the question. But for better understanding some more explanations are needed. Otherwise the answer may become flagged and deleted ;-) – marsh-wiggle Nov 27 '18 at 23:22
