On a 64-bit version of Windows Server 2003, COM+ functionality is disabled and the COM+ System Application service cannot be restarted.
Your System event log may contains messages similar to:
Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7009 Date: MM/DD/YYYY Time: HH:MM:SS User: N/A Computer: <Computer Name> Description: Timeout (30000 milliseconds) waiting for the COM+ System Application service to connect.
