System hangs at same time on the same day each month with Windows NT Server - PC Server 720

Resolving The Problem

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 <F9> to Disable
6. Press <F3> 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.
