ok..let me be more specific.
Check the TIME on the NetApp and the Client and the DOMAIN Controllers.
If time is off someplace, getting to the name will not work.
BE SURE TO VERIFY TIME IN UTC FORMAT
ONTAP: cluster date show -utc
Windows: get-date -AsUTC (must have powershell 7.1 or higher)
Make sure all dates are within 5 minutes of each other
