Network Problems
This section provides some common causes and solutions for network problems. However, the
process of debugging network cabling is not discussed.
Table 4-11
Solutions for Network Problems
Problem Cause Solution
System does not detect a
network controller.
1. Possible driver problem
2. Possible failed network
controller
1. Load latest version of Compaq Workstation SSD for
Windows NT.
2. Replace the system board.
System Setup utility
reports unprogrammed
EPROM.
1. The network controller is
defective.
2. Network drivers are not
loaded.
1. Replace the controller or the system board.
2. Boot the workstation without the network drivers. Using a
system boot diskette, reconfigure the network controller.
Diagnostics reports a
failure.
1. The cable is not securely
connected.
2. The cable is attached to the
incorrect connector.
3. There is a problem with the
cable or a device at the
other end of the cable.
4. The network controller is
defective.
5. Network controller interrupt
or memory overlaps the
interrupt or memory of an
expansion board.
1. 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.
2. Be sure the cable is attached to the correct connector.
3. Be sure the cable and device at the other end are
operating correctly.
4. Replace the controller or the system board.
5. Run Computer Setup and modify the network controller
memory value.
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 the driver
parameters match the configuration of the network
controller.
2. Select the Network icon at 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.
