Network Problems
continued
Problem
Cause
Solution
Diagnostics passes, but the
system does not communicate
with the network.
1.
Network drivers are not
loaded, or driver parameters
do not match current
configuration.
2.
The network controller is not
configured for the
workstation.
3.
The network controller
interrupt or memory
overlaps the interrupt or
memory of an expansion
board.
1.
Be sure the network drivers
are loaded and that the
driver parameters match the
configuration of the network
controller.
2.
Select the Network icon in
the Control Panel.
Reconfigure the driver if
necessary, using the
Network Setup found in the
Control Center.
3.
Run Computer Setup and
modify the network
controller memory value.
Network controller stopped
working when an expansion board
was installed.
1.
Network drivers are not
loaded or driver parameters
do not match the current
configuration.
2.
The cable is not securely
connected.
3.
The network controller
interrupt or memory
overlaps the interrupt or
memory of another
expansion board.
4.
The network controller
requires drivers.
5.
The files containing the
network drivers are
corrupted.
1.
Be sure the network drivers
are loaded and that the
driver parameters match the
configuration of the network
controller using Network
Setup found in the Control
Center.
2.
Be sure the cable is securely
attached to the network
connector and the other end
of the cable is securely
attached to the correct
device.
3.
Run Computer Setup and
modify the network
controller memory value.
4.
Verify that the drivers were
not accidentally deleted
when the drivers for a new
expansion board were
installed.
5.
Reinstall the network drivers
using the Compaq Restore
CD, then run Computer
Setup.
