Circular dependency: The Infrared Monitor service depends on a service in a group which starts later.
Source
Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.
Dependency Walker is also very useful for troubleshooting system errors related to loading and executing modules. Dependency Walker detects many common application problems such as missing modules, invalid modules, import/export mismatches, circular dependency errors, mismatched machine types of modules, and module initialization failures.

Infrared MonitorThe Infrared Monitor service enables you to share files and images through infrared connections. This service is installed by default on Windows Vista and Windows XP if an infrared device is detected during operating system installation.
If the Infrared Monitor service stops or is disabled, files and images cannot be shared through infrared connections.
This service startup type is Automatic.
Interactive Services DetectionThe Interactive Services Detection service enables user notification of user input for interactive services, which enables access to dialog boxes created by interactive services when they appear. If this service is stopped, notifications of new interactive service dialog boxes no longer function and there may no longer be access to interactive service dialog boxes. This service supports the new service isolation feature in Windows Vista.
In Windows XP, Windows Server 2003, and earlier versions of the Windows operating system, all services run in the same session as the first user who logs on to the console. This session is called Session 0. Running services and user applications together in Session 0 poses a security risk because services run at elevated privilege and therefore are targets for malicious users who are looking for a way to elevate their own privilege level.
The Windows Vista operating system mitigates this security risk by isolating services in Session 0 and making Session 0 noninteractive. In Windows Vista, only system processes and services run in Session 0. The first user logs on to Session 1, and subsequent users log on to subsequent sessions. This means that services never run in the same session as users' applications and are therefore protected from attacks that originate in application code. Because Session 0 is no longer a user session in Windows Vista, services that are running in Session 0 do not have access to the video driver in Windows Vista. This means that any attempt that a service makes to render graphics fails. For example, if a device installer runs in Session 0 and the installation program creates a dialog box in Session 0 that requires user input to continue, the device installation never completes because the user does not see the dialog box. From the user's perspective, the device installer is hung because it has stopped progressing and the user has no way to resume it. Basically, any functionality in a service or a service-hosted driver that assumes the user is running in Session 0 does not work correctly in Windows Vista.
As a result of this issue, the option of enabling the Interactive Service Detection Service will be available for customers who have services from earlier versions of Windows that send user interaction dialog boxes to Session 0 instead of the corresponding user's session.
The service startup type is Manual start by default. The service starts only when a visible dialog box that is not a command window is detected. If the service is started, then users will be notified when a dialog box or window (including a command window) appears in Session 0. Information about each of the last 10 dialog boxes will appear in turn if more information is shown. This will help ensure that deployment testers are aware of services from earlier operating systems in their environment and have the opportunity to contact the vendors for updated services.
