In order for the ARP command to work on Windows , the ARP table on the PC must have
at least one IP address deÞned other than its own. If the ARP table is empty, the

ARP -A
at the DOS command prompt to
verify that there is at least one entry in the ARP table.
If there is no other entry beside the local machine, ping another IP machine on your
network to build the ARP table. This has to be a host other than the machine that you're
working on. Once there is at least one entry in the ARP table, use the following
commands to ARP the IP address to the MPS and make the MPS acknowledge the IP
assignment.
NOTE: There should be replies from the IP address if the ARP command
worked.
When the MPS receives the ping packet, it will notice that its IP address is not set and
will send out broadcasts to see if another node is using the speciÞed address. If no
duplicate is found, the server will use the IP address and will respond to the ping packet.
The MPS will not save the learned IP address permanently; this procedure is intended as
a temporary measure to enable EZWebCon to communicate with the server, or allow an
