SYMPTOMS

RPC-based programs that run on a Windows 2000-based client may not work when the client connects to UNIX servers (such as SUN or Hewlett-Packard).

CAUSE

When you use structures as parameters in RPC calls on Windows 2000, the call may not work and may generate "RPC_S_INVALID_TAG (1733)" or "RPC_X_BAD_STUB_DATA (1783)" errors.
The problem occurs on a Windows 2000-based client that is attempting to communicate with a server platform that uses a different byte ordering. SUN and Hewlett-Packard use big-endian, DEC (like Windows) uses little-endian.
