Access Easy Controller
command should be performed from a computer on the same local sub-net as the technician's
computer.
Decision:
Did the customer receive a response to the "ping" command?
Yes - Proceed to step 7.
No - There is a network configuration problem.
If the "ping" command returned the message "Request timed out," then there is a basic net-
work configuration error, possibly the setting of the IP address or subnet mask assigned for
the Access Easy Controller. Or the customer's router may not be configured properly. Review
these items with the customer.
If the "ping" command returned the message "Network unreachable", then the customer's
router or proxy server may be configured incorrectly, or the IP address, netmask, or gateway
provided for the Access Easy Controller are incorrect.
In either case, do not proceed further in this test procedure until this step is successfully
passed.
Step 7 - Confirm that the technician's computer can "ping" the customer's computer and/or
gateway on the same local sub-network.
Procedure:
From the technician's computer, open a DOS window and send a "ping" command to a cus-
tomer computer on the same local subnet. Ideally, you should "ping" the computer that was
used in the previous steps.
Question:
Was a response received to the "ping" command?
Yes - Proceed to step 8.
No - There is a network configuration error.
If the "ping" command returned the message "Request timed out," then there is a basic net-
work configuration error. Probably sub-net mask or gateway assigned for the Access Easy
Controller is incorrect. Or the customer's gateway or router may not be configured properly.
If the "ping" command returned the message "Network unreachable," then the IP address or
netmask of the controller may be wrong.
If the computer uses a gateway, try to "ping" the gateway from the technician's computer.
If a response is received, then the customer's gateway or router may have a configuration
problem.
