Turning off ARP requets on Win XP

[Guest]

Hello,

I have this situation where a real-time OS client appication is downloading
a file off a Windows XP host running SFU NFS Server. The connection between
the two is a direct gigabit card-to-gigabit card connection using a crossover
cable. The problem is during this download, sometimes XP sends out an ARP
request to the RTOS box. This ARP request and subsequent response from the
RTOS box causes the RTOS client App to miss its timing deadline. Any ideas on
how I could disable these ARP requests on the XP box?

Thanks,
Keith

With some misgivings...
Hard-code a static ARP entry into the arp cache:

Go to a command prompt, and enter arp /? for the syntax.

arp -a will display the arp cache;
arp -s will add a static entry.

See the example useage at the end of arp /?

Then XP will not need to ARP for the MAC address, it will always be in
cache.
