Creating DirectX device fails in remote desktop

I have an application that uses DirectX to capture the screen. The application works fine locally, however when I run it through a remote desktop session the IDirect3D9::CreateDevice function fails:

    d3dpp.Windowed=WINDOW_MODE;
    d3dpp.Flags=D3DPRESENTFLAG_LOCKABLE_BACKBUFFER;
    d3dpp.BackBufferFormat=ddm.Format;
    d3dpp.BackBufferHeight=nDisplayHeight=gScreenRect.bottom =ddm.Height;
    d3dpp.BackBufferWidth=nDisplayWidth=gScreenRect.right =ddm.Width;
    d3dpp.MultiSampleType=D3DMULTISAMPLE_NONE;
    d3dpp.SwapEffect=D3DSWAPEFFECT_DISCARD;
    d3dpp.hDeviceWindow=hWnd;
    d3dpp.PresentationInterval=D3DPRESENT_INTERVAL_DEFAULT;
    d3dpp.FullScreen_RefreshRateInHz=D3DPRESENT_RATE_DEFAULT;

    if(FAILED(g_pD3D->CreateDevice(D3DADAPTER_DEFAULT,D3DDEVTYPE_REF,hWnd,D3DCREATE_SOFTWARE_VERTEXPROCESSING ,&d3dpp,&g_pd3dDevice)))
    {
        ErrorMessage("Unable to Create Device");
        return E_FAIL;
    }

I am using Windows 7 to access Windows Server 2008 R2 with RDP.

What exactly is wrong here? I read that its possible to do use Direct3D through RDP.

Solution

Haha, the problem was I had not the DirectX drivers installed. After it works!
