Network DDE is a technology that allows applications that use the DDE
transport to transparently exchange data over a network. It consists
of two major components:
- The NetDDE agent. This is a service that acts as a proxy for the remote
DDE application. It communicates with all local DDE applications, and
with remote NetDDE agents using NetBIOS as shown in this chart:

NDdeShareDel, and so on. This DLL is usually named NDDEAPI.DLL.
In the interests of backwards compatibility, Windows 95 includes a NetDDE
agent and a 16-bit NetDDE API DLL. However, Windows 95 does not include a
32-bit NetDDE API DLL. Consequently, 32-bit applications that use NetDDE
API functions will need to thunk to the 16-bit NETAPI.DLL.
