A few mostly minor things come to my mind.

Style inconsistencies.

Please avoid LPVOID and similar pointer types. Just use void **.

Since you're using GUID_NULL as a way to signal that no guid is set it would be a good idea to try to pass it to SetSP and see if you still get DPNERR_DOESNOTEXIST when you call GetSP.

Otherwise this looks good to me.
