SYMPTOMS
If you add a role for a COM+ application that is not running, the role base security check may break for a COM+ application that is running. Additionally, you may receive the following error message in the COM+ event log:

COM+ Security Warning

Event ID: 4098

A method call to an object in a COM+ application was rejected because the caller is not properly authorized to make this call. The COM+ application is configured to use Application and Component level access checks, and enforcement of these checks is currently enabled. The remainder of this message provides information about the component method that the caller attempted to invoke and the identity of the caller.



CAUSE
This problem occurs because the security is checked between two components in the same application. Normally, no access should be checked between components in the COM+ application.
