windows server 2025 join domain failed

[Zhangyufan]

I have a test lab with ONTAP simulator at 9.13.1 version, and Microsoft published windows server 2025 last month, so I want test ONTAP with new OS.

1.Windows server 2025 is installed and active directory service is installed.

2. During the cifs create procedure, it shows an error: Machine account creation procedure failed.

3. From wireshark capture, it shows kpasswd replyed an error.

The user account in this kb used to add a computer account is using an incorrect password 

Machine Account Creation Procedure Failed - KRB5KDC_ERR_PREAUTH_FAILED - NetApp Knowledge Base

Or the user credentials are incorrect   Machine account creation procedure failed with KRB5_REALM_UNKNOWN error - NetApp Knowledge Base

If you check Interoperability Matrix for CIFS, Windows 2025 Server is not yet listed, so the validation is not executed yet. 

The error is pointing to a duplicate/reused account on Domain Controller for the SVM.

Please retry posting the full secd log for cifs create call to understand the reason for the failure

It seems there is a problem on Microsoft side for kpasswd (Kerberos password change service) and it is investigated by Microsoft at the moment.
