ARP is defined in RFC 826. In other words, it's defined by the same standards body that defines IP protocols. ARP is used to map IP addresses to data-link-layer addresses. It's an essential component of an IP implementation. But let's not get into one of those arguments again. ;-) The original poster says that the sender is setting its own data-link-layer address to FF FF FF FF FF FF. This would indicate a major bug in the driver. It makes one wonder if the poster is misinterpreting the protocol analyzer output? Can you send it to us?? Sorry, if this assumption is wrong but the error that you report is so bizarre, we have to wonder..... Priscilla >-Patrick > > >>> "Steven A.
