System Application is located in the COM+ Applications folder in the Component Services snap-in. System Application manages configuration and deployment in Component Services. The default authentication level that System Application uses for calls is Packet Privacy, which provides the highest level of security.


For security reasons it is strongly recommended that the Authentication Level of System Application remain at its default value of Packet Privacy.

So that changes to the system — such as installing a COM+ application or adding a computer — can be made, security must be set to define who can administer the environment. You can use the following procedure to enable security on System Application by defining who belongs to the Administrator role. Only members of the Administrators group on your computer can belong to the Administrator role of System Application.

Membership in Administrators, or equivalent, is the minimum required to complete this procedure. Review the details in "Additional considerations" in this topic.
