System.UnauthorizedAccessException from COM+ app

[Guest]

Hi,

I am trying to connect to a COM+ library application from a Windows forms
exe. When I try to create the serviced component I get a not authorized
exception.

The serviced component has these attributes:

[EventTrackingEnabled(true)]
[JustInTimeActivation(true)]
[Transaction(TransactionOption.Required, Timeout = 2000)]
[SecurityRole("Developer")]
[SecurityRole("Tester")]
[ComponentAccessControl(true)]

What am I doing wrong?
How can I configure my client so it has enough security?

Hi

Based on my understanding, you have created a Serviced Component and put it
into COM+ and run it as a Library Application. For a Library Application,
it will run in the Creator's process just as a common dll.

By default the client(Winform) will use the user's credential who lauched
the client to access to the COM+ application, you so may check if your
acount has the permission to access the COM+.

Also I think you may try to start from the example in the msdn below to see
if that works for you.

Here is also a good start for your reference.
