H137828 - PC SERVER 720 HANGS WITH WINDOWS NT SERVER SYMPTOM: The PC Server 720 hangs at the same time on the same day each month. PROBLEM ISOLATION AIDS: All of the following must be true for this tip to apply: - Windows NT Server hangs; it does NOT trap to a blue screen - The Real-time-clock power-on mode is enabled FIX: Disable the Real-time-clock power mode as follows: 1. Boot the Reference Diskette 2. Select Set Features 3. Select Set power-on features 4. Select Real-time-clock power-on mode 5. Press to Disable 6. Press to Exit The Real-time-clock mode is used to set a wake-up time and day for the Server. If this mode is enabled and then the Server is powered off, the Server will remain off until the wake-up time. At that time, the Server will power up automatically. But if the Server is up and running with Windows NT and the Real-time-clock is enabled, the Server will hang at the exact day and time that the wake-up is set for. Other Operating Systems are not affected. Windows NT is a trademark of Microsoft Corporation. May 21, 1997
