In case of any non-OES target validation errors, use -i option to establish the non-OES junction without verifying the existence of the target server or share:
dfstool -c /media/nss/VOL1/dir1/junc1 -t target_server_or_ip_address/share_name/path_to_target_folder -T non-oes -i
(or)
dfstool -c /media/nss/VOL1/dir1/junc1 -t target_server_or_ip_address/share_name/path_to_target_folder -T non-oes --ignore-targetpath-check
dfstool -m /media/nss/VOL1/dir1/junc1 -t target_server_or_ip_address/share_name/path_to_target_folder -T non-oes -i
(or)
dfstool -m /media/nss/VOL1/dir1/junc1 -t target_server_or_ip_address/share_name/path_to_target_folder -T non-oes --ignore-targetpath-check
