I guess after domain name change filer won’t be able to authenticate users. Just rerun “cifs setup” after domain name change. This does mean short outage for CIFS services. You may need to adjust your DNS configuration as well.
Thanks for the response. This will be a tedious task for storage team. I have one more query.
What happens to the users who are having access to the shares.. for example assuming the filer is part of windows domain "XYZ. Currently the users are added to the shares as "XYZ\username".. and the domain name is changed to ABC..? When we rerun CIFS setup all these user access entries will get adjusted automatically to "ABC\username"..?
