I know I've seen others run into this, but I didn't see a clear resolution in the threads I looked up.
When our Win7 machines start up, I see a gratuitous ARP packet from 0.0.0.0 to the same IP address that the host obtains via DHCP. This is obviously a check by the PC to make sure the address the DHCP server is offering is not in use. I have dynamic ARP inspection enabled on my switch, and every time our PCs (think 1000+) wake up in the mornings, I get a flood of false positives, since 0.0.0.0 is obviously not the address that exists in my snooping database.
Can we disable this feature and avoid false positives by disabling gratuitous ARP in the registry, or is there a better way to do it?

Try setting this to 0

Thanks - I figured this was the appropriate way to take care of it, just didn't know if there was a separate workaround that was more preferred.
This is what we will do. :)
