PPPoE system flow

Hi,

I've got a PPPoE source. I've compiled and installed it successfully. When I tried to connect to Internet by using it, I got this error: broadband modem not found.

Is this error generated by Windows or PPPoE driver? Is it possible to use debug tool (e.g. SoftIce) to trace where the problme occur? If so, how?

I have used regmon: http://www.sysinternals.com/ntw2k/source/regmon.shtml to check the PPPoE system flow. The "modem not found error" occur before PPPoE driver is loaded. So I think this error is triggerred by Windows.

Are some drivers not loaded?
