Hi Lan,
Which version of OS and IIS do you use?
As for you issue, I think you may try to use impersonate.
Here is a KB Link.
306158 INFO: Implementing Impersonation in an ASP.NET Application
http://support.microsoft.com/?id=306158
Impersonate will let you use the authenticated user to access the COM+
component.
e.g. you set the Windows Integated authentication in the IIS setting, then
you will use the current logon user to access the webpage, and then access
the COM+ component. You also need to set the logon user the rights to
access the COM+ component.
You may run the dcomcnfg in the run dialog,navigate to the Component
Service/Computer/Mycomputer, right click on the Mycomputer,and select the
default com security tab. Then press the each Edit button and add the
current logon use to the permission dialog. This will add the current logon
use the lauch and access right.
You may have a try and let me know if this does the job for you.

Peter Huang
