Ok here is my problem or at least I think so. I think my network seams to be slow and I cant even seem to hand multicast our school district went to Altiris to deploy images to computer other schools are able to image a whole lab of computers with out any problems. I end up getting mixed results some work fine while others seam to time out and hang. So I downloaded Wireshark and did a quick capture there seam to be a lot of ARP requests going on is this normal. I dont know much about monitor network traffic but there sure seems like a lot of them. I would say they make up for almost 90% of what I captured. I have a feeling the equipment can handle multicast but have a sneaking feeling something is miss configured that would speed things up. All the major switches in my school are 3com 3250s all tied in by fiber in the 3com core builder 9400. Most of my labs have Netgear 16 port switches or 24 in them.
