This morning the server was preventing users from logging in so I went to check and according to the attachments I will post down below
It appears online and responds to ping requests, but on its screen it does not have any available network connections and does not allow Administrator log on neither AD users to log in to the network nor access the folders because it says something is wrong
with their credentials, which in fact is not. Somehow the server left the domain and maybe it's on a private network I suppose.
What has already been done:
Start with the last valid configuration (not resolved)
Log in safe mode (starts in protected mode and does not let the administrator do anything)
What was not done:
Exploit to Reset Password with Vulnerability CVE-2017-0213_x64
Other Hacking Methods ...
Frequently Asked Questions:
