How NTLM works:

1. Client Request
The client initiates access by sending a request to the server, including their username.

2. Server Challenge
The server generates a random 16‑byte value, known as a challenge (or nonce), and returns it to the client.

3. Client Response
The client encrypts the challenge using the NT hash of their password and sends the resulting response back to the server.

4. Server Forwarding
The server passes the username, the original challenge, and the client’s response to the domain controller.

5. Domain Controller Verification
The domain controller retrieves the user’s NT hash from its database.
It encrypts the same challenge with this hash.
It compares its computed result with the client’s response.

6. Authentication Decision
If the values match, authentication is successful.
The domain controller informs the server, which then grants or denies access accordingly.
