SYMPTOMS
Consider the following scenario. You create a distributed application that uses a custom channel. The custom channel implements the IRpcChannelBuffer interface. However, the custom channel does not implement the IRpcChannelBuffer2 interface. A Microsoft Windows 2000 client application makes a Microsoft Component Object Model (COM) call. This COM call must marshal user-defined data types that contain a SAFEARRRAY data type to a Microsoft Windows XP Service Pack 2 (SP2)-based COM server.

In this scenario, the Windows XP SP2-based server may reject the call, and the Windows 2000 client application may receive an error message that resembles the following:

0x800706F7 (The stub received bad data)



CAUSE
This problem occurs because the Oleaut32.dll file cannot determine the version of the negotiated Network Data Representation (NDR) protocol. Therefore, the Oleaut32.dll file cannot determine whether the server supports UDTs, and the Oleaut32.dll file incorrectly marshals the SAFEARRAY data type.
