SYMPTOMS
When a Windows 2000-based computer starts, a packet that contains the computer's TCP/IP address is broadcast on the network to prevent the use of duplicate addresses on the same network. This is called a gratuitous Address Resolution Protocol (ARP) packet. Routers and other network hardware may cache routing information that is obtained from multiple gratuitous ARP packets. For both performance and maintenance reasons, you can disable this feature in Windows 2000.
Note that the following Microsoft Knowledge Base article mentions setting the ArpRetryCount value in the registry to 0 (zero) to stop the gratuitous ARP packet, but this method results in three gratuitous ARP packets being sent:

CAUSE
This issue occurs because Windows 2000 recognizes only data values 1, 2, and 3 for the ArpRetryCount value. If you use a value of 0 (zero), the default value of 3 is used.
