OLE Server in DLL

Enviroment: Visual C++ 4.1 / Win95-WinNT 4.0

 I am trying to move an OLE server from an Exe to a DLL.

 When I try to inplace activate the server from the DLL it is missing 
the Interface IViewObject2 and Barfs? Works fin if the Server is an 
EXE.

 Anybody know if your have to do something special if your server is 
in a DLL? Dll is not an extension Dll.

TIA

Bill

I just took a quick look at my ole dll and I have the following defined

/////////////////////////////////////////////////////////////////////////
////
// Special entry points required for inproc servers

STDAPI DllGetClassObject(REFCLSID rclsid, REFIID riid, LPVOID* ppv)
{
	AFX_MANAGE_STATE(AfxGetStaticModuleState());
	return AfxDllGetClassObject(rclsid, riid, ppv);
}

STDAPI DllCanUnloadNow(void)
{
	AFX_MANAGE_STATE(AfxGetStaticModuleState());
	return AfxDllCanUnloadNow();
}

// by exporting DllRegisterServer, you can use regsvr.exe
STDAPI DllRegisterServer(void)
{
	AFX_MANAGE_STATE(AfxGetStaticModuleState());
	COleObjectFactory::UpdateRegistryAll();
	return S_OK;
}

After further investigation of this problem here is what I have found.

 If you call ::OleCreate on an MFC InPlace Server (COleServer) that 
is OUTOFPROC (an exe) you get the IViewObject2 Interface. If
it is INPROC (a dll) you don't. I have searched the Knowledge base at 
microsoft.com, MSDN, newsgroups  and the OLE 2.0 Documentation.
But to no avail you guys are my last hope :(
