Hi,
Unless your app uses some sort of packet driver software (extremely unusual) the network specialist? is out of his depth. It is more like they have set the workstations up for jumbo packets and some other device (server, switch or router) can't handle the packet size.

It took me 5 minutes before I could get up off the floor laughing when I read the net specialists ?? comments, must admit it is the best one I have seen in quite a while.

>We isolated the source of the ‘Fragmented Packets’ by excluding all networked devices and creating a restricted network consisting of only the broadband router, the server and the workstation connected via a Gigabyte switch.  Initially there was no ‘Fragmented Packets’, however, as soon as <VFP application> was run the ‘Fragmented Packets’ started again.
