Under DOS, the NetShareAdd, NetShareDel, and NetShareEnum APIs can be run on or called from a DLS workstation if DLS Peer service is installed. The user level security function for DOS LAN Services allows a DLS peer workstation to run similar to an OS/2 server or an OS/2 peer workstation. In this mode, resources are shared by the DLS peer workstation based on access rights an administrator assigns to an individual user or a group of users.

The rest of the APIs in this category can be run only on a remote server and, if called locally on a DLS requester, the NERR_RemoteOnly error code is returned.
