The folder "Documents" is shared. The user can create and delete documents when on the local PC, but can only read documents when accessing them remotely. Which of the following should be adjusted?

The Read-Only file attribute applies uniformly to both local and remote access, so it would prevent local writes as well, which is not the reported behavior.

Windows evaluates both NTFS permissions and Share Permissions for remote access, applying the most restrictive result. If Share Permissions are set to Read-only for the relevant user or group, remote users cannot write or delete files even if NTFS permissions grant Full Control. Because local access bypasses share permissions entirely, the symptom of full local access but read-only remote access points specifically to Share Permissions being too restrictive.

Firewall settings control network connectivity and port access, not file-level read or write permissions.

NTFS permissions apply to both local and remote access equally, so restrictive NTFS permissions would also block local writes, contradicting the described symptom.
