Applicable to: World-Wide

Symptom:
LAN attached clients may lose connection with the server or experience a slow server response time.

Problem Isolation Aids:
All of the following must be true for this Tip to apply:

6. Select "Advanced Setup".
7. Select "System Resource Balance".
8. Use the direction keys to toggle choice to "MCA biased" then press the <Esc> key to exit.

11. Select "Exit Setup" then press the <Enter> key.
12. Select "Yes Exit the Setup Utility", then press the <Enter> key. The system will now reboot.
