This property corresponds to the "Network Library", "network", and "net" keys within the connection string.
If the value passed in is null when you try to set the property, the property is reset. If the value has not been set and the developer tries to retrieve the property, the return value is String.Empty.
Supported values for this property include dbnmpntw (Named Pipes), dbmsrpcn (Multiprotocol), dbmsadsn (AppleTalk), dbmsgnet (VIA), dbmslpcn (Shared Memory) and dbmsspxn (IPX/SPX), and dbmssocn (TCP/IP). The corresponding network DLL must be installed on the system to which you connect. If you do not specify a network and you use a local server (for example, "." or "(local)"), Shared Memory is used.
