Ok. Thanks for the info on these items Rick.

>>It is actually an ATL COM DLL I created in VC++. I used the "Simple Object" object which I'm wondering might be the problem, thinking I needed the "Internet Explorer" object instead. It is an invisible object for obtaining User/Machine info that will be used in an Intranet scenario, so we should be able to have the object already on most users' machines.

If it's signed a dialog displays with the digital signature to verify the authenticity of the control. IOW, when I create a control I sign it with my West Wind Certificate and it says so. Nobody can tamper with the file in the CAB (ie create a new CAB with a different file in there to take over your machine) once it's signed.
