Lost previous AD

[reis]

Hello guys,

Can anyone help me with this case:

We had an issue that caused our AD to fail completely.

We have no way to recover.

We had to create a new AD from scratch.

But after reconfiguring CIFS and mapping the shares,

We came across "Access Denied"

Can anyone share some solution

Filer: FAS8020HA
Ontap Date: 8.2.5P5 Data Ontap 7-Mode
Old Domain: Windows Server 2012R2
Nwe Domain: Windows Server 2016

You mentioned, after reconfiguring CIFS;  Does that mean CIFS setup is completed successfully and the CIFS server machine account is created in your 2016 AD domain ?

You can do few checks:
1) Is filer time and the AD time in sync (Within 5 mnt apart)
2) Make sure SMB2 is enabled on filer: (SMB1 is disabled by default in 2016, so it (DC) must communicate via SMB2)

Enable this:
filer> options cifs.smb2.client.enable on

Try again, else share rdfile /etc/messages
