ASP & COM+'s Enable Object Construction

I have a site that has been working for a few years now. the web site
is using a DB Access DLL written in VB. the DB's connection string is
passed to the DLL using the COM+ enable object construction option and
using CreateObject in the ASP code.

we are now trying to install this application on a new server and we
have a very strange problem:

Server info: Win2K SP4. the COM+ package is a server package with
identity set to be the administrator.

When the ASP page is trying to call createobject the call runs fine
even though it is not going through COM+ (if i look at the currently
running objects in my package, the count is 0) and the connection
string is empty since no construction string was passed to the DLL

if i run the same createobject call in a VBS file while logged in as
the administrator, it does go through COM+ and the connection string
is fine.

so obviously it is some kind of permissions problem but i do not know
where. i have tried setting the IIS's site to use the administrators
account for anonymous access but that did not solve the problem.
