Ok, it was unix, I updated it to ntfs

cifs-vf-01@irt-na06> qtree security /vol/media1 ntfs

cifs-vf-01@irt-na06> Thu Sep  4 08:27:49 PDT [irt-na06:wafl.quota.sec.change:notice]: security style for /vol/media1/ changed from unix to ntfs  

I still get the same “write protected” error when attempting to copy to the remapped drive

Should I re-run cifs setup?

I want the simplest non-AD (since only one (service type) account will be accessing this share)

(1) Active Directory domain authentication (Active Directory domains only)

(2) Windows NT 4 domain authentication (Windows NT or Active Directory domains)

(3) Windows Workgroup authentication using the filer's local user accounts

(4) /etc/passwd and/or NIS/LDAP authentication
