I’m facing a problem while accessing COM+ server application from VB application where the role-based security is enabled.

My COM+ server application has following settings.

1. Checked “Enforce access checks for this application”
2. Selected security level as “Perform access checks at the process and component level. Security property will be included on the object context. The COM+ security call context is available.”
3. Authentication level as “None”
4. Impersonation level as “Impersonate”
5. Identity as “This user” (System Administrator)
6. Created a Role and added specific user (user where the VB application calls)
7. Assigned the role into each Components, Interfaces & Methods in the application

Even though, its failing to access COM+ application. What do I need to do?
