Description:
In this video, we explain what happens when a Domain Controller (DC) fails and how client authentication works in different scenarios. Learn how clients switch to an additional DC for login and how cached credentials allow users to sign in when all DCs are down.

🔹 Topics Covered:
✅ What happens when a Domain Controller fails?
✅ How clients authenticate with an additional DC
✅ What happens if all Domain Controllers fail?

🔹 Key Scenarios:
🔸 DC Failure with Additional DC Available – Clients authenticate using the backup DC.
