Where exactly is this being called from? And which thread is it in? Is it
in the same thread as the COM object?

Make the following tweaks:
template <class T> HRESULT
TEvents_5200Server<T>::Fire_OnOpen(void)
{
T * pT = (T*)this;
HRESULT hRes; // <-- here
pT->Lock();
IUnknown ** pp = m_vec.begin();
while (pp < m_vec.end())
{
if (*pp != NULL)
{
m_EventIntfObj.Attach(*pp);
hRes = m_EventIntfObj.OnOpen(); // <-- here
m_EventIntfObj.Attach(0);
}
pp++;
}
pT->Unlock();
return hRes; // <-- here
}

What is the actual return value of m_EventIntfObj.OnOpen() when the event
fails to be triggered? Chances are, it is not S_OK. IT will probably be
more like RPC_E_WRONG_THREAD.
