APPENDIX D

Troubleshooting SBC Express

Please refer to this list if you are having problems using SBC Express or if you receive an error
message. If after troubleshooting, you are still having problems, then you should contact the
numbers listed in Appendix A.

Step Problem

Solution

Minimum
Resources

SBC Express verifies minimum requirements on
several resources including hard drive space, RAM,
operating system level, and processor speed and
family.

If any of these resources are under the required value,
an error will display describing which resource did not
meet the requirement.

Update your computer to the recommended

resource level.

Installing
Network
Interface Card

When installing Network Interface Cards the
installation process may ask for the original installation
disk.

You may have to provide an installation CD-
ROM for the installation of the drivers to be
successful.

Incompatible
Adapter

This scenario can occur when a machine had a
previous NIC or Network Adapter installed, but the
physical device is missing or was misconfigured.

Use the “Fix” button to launch the appropriate

system control panel along with context sensitive
help. The help provided will guide you through
the steps to disable or remove the adapter.

Missing Internet
Protocol

This scenario can occur if Client for Microsoft
Networks is not installed with the TCP/IP protocol or
if the NIC is installed without binding TCP/IP to the
NIC.

Use the “Fix” button to launch the appropriate
control panel and context sensitive help to guide
you in binding TCP/IP to the network adapter.

Disabled
Network Adapter

This scenario can occur when a NIC is present in the
system, yet the adapter has been disabled.

Use the “Fix” button with context sensitive help
to guide you through enabling the adapter.

Ping Test

The Ping Test is usually accomplished within the
Configure TCP/IP step, where SBC Express pings the
default gateway. An explicit IP address can also be
used.

Failure during this test can occur from invalid
network settings, the Ethernet cable not being
plugged in, the DSL modem not being in synch,
or if the specified IP address does not allow a
ping.

Make sure your Ethernet cable is plugged in and
powercycle your DSL modem. Use the “Retry”
button to try the test again.

DNS Test

The DNS Test will determine the currently defined
DNS servers, attempt to ping them, and upon a
successful ping, will resolve a specified hostname to an
IP address.

This test can fail if the DNS server is invalid. If
you entered static IP information, ensure you
entered the DNS servers correctly.
