We have a user on our domain which we need to allow access to a subfolder in a shared network drive. This user has read only permissions on both the QNAP SMB and Windows ACL for this folder. However, when I log on as this user and try to navigate to this folder I get the message "Windows cannot access \\IP Address\QNAP Shared Folder\Sub Folder". When I try to navigate to just "\\IP Address\QNAP Shared Folder" it asks for credentials, but any subfolders within that it just says do not exist.
The only way I can seem to get this user to access this sub folder is to give them read access to every root folder (This sub folder is actually about 5 deep). However this is not an option in this case.
The QNAP model is TS-EC879U-RP, with the latest firmware. Although this shouldn't really make a difference.
Has anyone encountered this before and what would be the method of giving a user Read Only access to a sub folder?
