Premature UPS Service Termination, Server Service Paused

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

A power break occurs and the UPS (uninterruptable power supply) service maintains the system for a short time. The UPS service times-out and terminates before power returns or the system can be prepared for shutdown. It also pauses the Windows NT Server service.

-or-

A power break occurs and power is restored before the battery runs out. However, the UPS service times-out and terminates, leaving the system vulnerable to the next power break (also pausing the Server service).

In both cases, the following events are logged:

   Event ID: 258
   Source:   UPS
   Type:     Error
   Error:    The description for Event ID (258) in Source (UPS) could
             not be found.

   Event ID: 3230
   Source:   UPS
   Type:     Warning
   Error:    A power failure was detected at the server.

CAUSE

Your UPS device does not have a low battery signal (or it was disabled) and, instead of handling this properly, the UPS service terminates prematurely. The problem is in the UPS service.

RESOLUTION

In either case, you should contact Microsoft Product Support Services for an updated UPS.EXE file. If your UPS and Server services are currently paused, restart them by choosing Services from Control Panel.
