Uninterruptible Power Supply Alerts Are Not Sent

When you connect an uninterruptible power supply (UPS) device to your Microsoft Windows Server 2003-based computer, and you turn on the option to send alerts from the UPS, alerts from the UPS are not sent.

This behavior occurs because the Windows Server 2003 Messenger service is not started. By default, the Messenger service is disabled in the Windows Server 2003 family. The UPS uses the Messenger service to send alerts. However, when you turn on the option to send alerts from the UPS in Power Options Properties, the Messenger service does not start, and you are not notified that the service is not started.

To resolve this behavior, you must start the Windows Server 2003 Messenger service. To do this, follow these steps:

1. Click Start, right-click My Computer, and then click Manage.
2. In Computer Management, expand Services and Applications, and then click Services.
3. In the right pane, double-click Messenger.
4. On the General tab, click Automatic in the Startup type list, and then click Apply.
5. In the Service Status area, click Start.
6. Wait for the Messenger service to start, and then click OK.
7. Exit Computer Management.
