Access error using VB6 Com in .Net

Hey Guys
I think many of you might have already encountered this problem before. Here is the problem

I have a COM dll in VB6. I am using it in a .Net DLL(C#). Then I try to use the functions from the .Net DLL from within an ASP.Net page(C#). There are no compilation errors at this point

When I try to browse the web page, I get an "Access denied" error at the point in my .Net DLL where I try to instantiate the class object from the VB6 dll

I have already tried
(i) Giving permissions to the VB6 dll object.
(ii) The VB6 dll object also reads a file and writes to it. I have given all permissions to the folder and files for the system user for ASP.Net even though there is no mention of the files at this moment
(iii) I have double checked if I have imported the VB6 dll as COM and not as .Net

I have run out of ideas at this point. So please feel free to post anything that you might think of.

Thanks and appreciate it.

If you are running with the default settings, ASP.NET will be trying to
access that file using the account ASPNET, instead of IUSR_* as you would
from ASP. If you are using impersonation, or have modified your
machine.config, then it will be using whatever that configuration results
in. Make sure that this account has permissions on this object.

Hello, We are in the process of examining our current main application. We have to do some major changes and, in the process, are questionning/validating the use of MS Access as front-end. The application is relatively big: around 200 tables, 200 forms and sub-forms, 150 queries and 150 repports, 5GB of data (SQL Server 2000), 40 users. I'm wondering what are the disadvantages of using Access as front-end? Other that it's not...

I've seen plenty of articles on this topic but none of them have been able to solve my problem. I am working with an Access 97 database on an NT4.0 machine, which has many Access reports.

I am at best a part time developer of Access databases. I use Access 2.0, as this is all my employer has on its computers.

I am self-taught from the help files that come with Access 2.0 and from painful experience. I've never attended any type of training course on how to develop databases in Access. I have no idea...
