Anyone any idea what is wrong here? In particular any idea why the xCall occurs almost immediately before the TMProxyImpl_Connect that would give it a channel to use?
(The software works fine with a native oleaut32.dll)
Ok, it looks like you are using builtin oleaut32 with native ole32, which in theory should work, but is probably mostly untested.

So, IRpcChannelBuffer::SendReceive is failing with RPC_E_FAULT for some reason. That could be caused by a number of things, but I would try turning on +seh logging as my first guess.
