SYMPTOMS
When you use the Component Services Microsoft Management Console (MMC) snap-in to delete a user from the Administrator role in the system application, you may receive the following error message:
CAUSE
This problem occurs when you define 17 or more users in roles for all of the COM+ applications. The problem occurs because of a query problem in the COM+ registration database in which the registration database is accessed incorrectly. The COM+ registration database is located in the SystemRoot\Registration folder.
In this case, COM+ requests a two-column query that asks for an indexed search by primary key on the RoleConfig table. However, the primary key in the RoleConfig table has three columns. Because the COM+ database support code does not check for errors on parameters, COM+ returns a first chance access violation in the system application after COM+ steps off array boundaries because COM+ assumes there are three columns. This problem is specific to 17 or more roles because there are more bad pointers when many records exist in the RoleConfig table.
