Propagation Errors with COM

We are having trouble passing error information across two COM boundaries. If you have :

VB calls ATL object1 which calls ATL object2 and ATL object2 throws an exception using

   return( Error( "Error Description", GUID_NULL, E_FAIL) );

We want an error to be propagated to the origionator (VB). The error number E_FAIL is available in VB but the  "Error Description" is lost somewhere along the way.

Any solutions? We are using MSVC6.0 and VB6.0
