Hi Stan,
Yes, we can check the security setting in the COM+ explorer. You may find
the three counterpart options by following the steps below.
1. Open COM+ explorer by running dcomcnfg
2. Navigate to the component we are using
3. right click on the component and click properties
4. select security tab
5. You may find security level, authentication level and Impersonate level
which is corresponding to the three options of
ApplicationAccessControlAttribute.
We can use the winform application but not the Webform application to
access to the Serviced component, so I suggest you check the eventlog's
security section on both the application proxy located computer and the
component located computer. If we do find we are using the same account to
access to the serviced component, but windows form succeeded while webform
application failed I think you may need to contact Microsoft PSS for
further and detailed trouble shooting, since we can not reproduce the
problem, it is hard to us to troubleshooting the problem in newgroup.
Thank for you understanding.
Best regards,
Peter Huang
