ASP.NET, ADODB and "Access Denied"

The old message looked a little stale, so I am re-posting it here. Anybody
have any ideas of what I could do?!? The previous responses to this
question are below. If you want to look at the original question, the
subject line is:

ADODB.NET and "Access Denied"

I have an ASP.NET page writtein in VB that uses ADODB. I just had to
force-install MDAC 2.8 after I tried to rollback to 2.6 (my web host uses
this, and I wanted to be compatible with them.) I had to manually install
all of the ODBC drivers and the rest of the DLL's, and now I am getting
"Access is Denied" errors on any page that uses ADODB.

How do I fix it? I already gave the ODBC drivers in the folders in
"c:\program files\common files\system\" full access rights for both IUSR
accounts and the ASPNET account.

Here is the output of the error:

Access is denied.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access is denied.

ASP.NET is not authorized to access the requested resource. Consider
granting access rights to the resource to the ASP.NET request identity.
ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or
Network Service on IIS 6) that is used if the application is not
impersonating. If the application is impersonating via <identity
impersonate="true"/>, the identity will be the anonymous user (typically
IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET write access to a file, right-click the file in Explorer,
choose "Properties" and select the Security tab. Click "Add" to add the
appropriate user or group. Highlight the ASP.NET account, and check the
boxes for the desired access.
