Default Behavior

Peer Networking Identity Manager is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Peer Networking Identity Manager service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Peer Networking Identity Manager fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the p2pimsvc service is not running because of the error.

Dependencies

If Peer Networking Identity Manager is stopped, the following services cannot start:
