Summary

You are attempting to bind the Authentication service to a Windows 2012 R2 Active Directory and the bind is failing

Problem

This is a known issue resulting from changes Microsoft have made to Server Security.

Solution

To resolve this issue, you will need to make some changes to Server Security settings as follows:

1. Log on to the domain controller
2. Open Administrative tools > Local Security Policy
3. Go to Local Policies > Security Options
4. Change "Network security: LAN manager authentication Level" to "Send LM & NTLM - use NTLMv2 session security if negotiated"
5. Apply these changes
6. Reboot the domain controller

If the above doesn't work, please run the following cmdlet under powershell:

Set-SmbServerConfiguration -EnableSMB1Protocol $true
