IIS7上的ASP经典无法创建COM对象

Question

I am getting permission denied errors when trying to create a com object in asp. The com object is a VB6 dll that has been registered. Procmon does not show any permission errors. I have granted permissions to the folder that contains the dll to the AppPool user and well as the authenticating user (IUSR). I noticed that there are a few people experiencing this problem with no definite solution. Please help!!

Answer 1

First thing you should check is that the permissions you have assigned to the folder have cascaded to the dll. I've seen a few cases like this where the dll had its own independent ACL rather than inheriting anything from its folder.

Answer 2

In procmon, can you see a successful read of HKLM\\Software\\Classes\\CLSID{YOUR_COMPONENT_CLASS_ID} ?

Maybe you have issues with rights in registry key associated to your component.

For a list of registry keys involved, please see the msdn docs .

Thanks for the responses. I have this working now. It was related to a another COM dll that was being called from the VB6 dll. However, I used to be able to step into VB6 from ASP/IIS6 but this now fails with a permissions error again. I will post another question for this. Thanks.
