Hmm... Is this on a single access point and/or channel? 802.11b or g?


When i run ipconfig /all the ip of the wins server is the same as one of the DNS servers. this means they are using DNS instead of wins right????
Well, not really as wins and dns can still be used in parallel. What's interesting though is that you still see this much wins bcast eventhough there's a wins server present. Can you tell me what Wins node type is set on the computers (also shown in ipconfig /all)? I would bet that they are set as b-nodes or m-nodes which are broadcast only and broadcast first then query wins server. If so, they should be changed to h-nodes (query first then broadcast) by dhcp options.


So im guessing there are too many users on the network and the school needs to add more broadcast domains, right ?
Well, 80 machines isn't necessarly too much for a single subnet, but personnaly I usually like to keep my windows hosts subnets under 50. For example, I'd ususally have a subnet (and vlan) for each computer lab, department... Not only does it help reduce broadcast traffic but it also prevents sniffing/connection hijacking through ARP spoofing/poisoning.

Thanks
You're quite welcome
