Have the protocol and service already configured?
Install the distinctive network driver for the workstation. Make sure that the
→
protocol, such as TCP/IP, and services are properly specified.
Is the transfer speed correct?
Open the network property dialog box in control panel to specify the "Link Speed
→
& Duplex" value the same as the value specified for HUB.
Did you update the system?
Installing a network drive after installation of the OS may cause unstable

Chapter 6.)
When an error occurs, the workstation does not operate exactly as set for [Automatically
restart]:
Even if you select [Control Panel] → [System] → [Automatically restart] in order to
automatically restart the workstation at occurrence of an error, the workstation may be
unable to restart automatically.
If the workstation does not restart automatically, restart it in manual mode.

A 3D application ends up with an error:
Check if the resolution, the number of colors, or the refresh rate has been changed
during operation of the 3D application.
Do not change the resolution, the number of colors, or the refresh rate during
