Preventing Memory Problems
 Make sure you have adequate memory installed on the system.
 Modify the NET.CFG file to load only necessary drivers.
 Modify the CONFIG.SYS file to load only necessary drivers.
 Check the AUTOEXEC.BAT and CONFIG.SYS files to make sure no
memory managers, such as HIMEM.SYS or EMM386.EXE, are being
loaded and that there is no DOS=HIGH statement in either file. Make sure
no DOS device drivers are being loaded.
For information about freeing up memory on a server, see “Freeing Server
Memory Temporarily” on page 139.
Preventing Power Supply Errors
An inconsistent power source is the most common cause of hardware
problems. It also produces the most devastating results.
Power outages cause workstations, network servers, print servers, and backup
devices to reboot. When this happens, all information stored in RAM is lost
and sometimes hardware is damaged.
Power spikes and brownouts can also cause a variety of hardware errors.
