I have a client with 30 PC's and 2 servers. The office broadband is horribly slow, and I need to diagnose it. Does anybody have any suggested strategies about where to start looking on this one?

Is the broadband up to par for the amount of users using it? As in how much bandwidth does it provide?

Take it step by step:

1. Is the broadband slow when you connect only 1 PC/Laptop?
2. Any software on the network that shouldn't be there (p2p, virus, malware, etc..)
3. How's DNS configured for the network?
4. Any monitoring tools available on the network?
5. Contact the broadband provider to hear if they have any issues.
6. ...

Try to get as much information as possible and use a checklist of things you have checked.

Do some content filtering on the router allowing only type of traffic that the business needs. That might reveal something.

Thanks - I'll try those steps out this afternoon.  Does anybody know of any network sniffing tools that will diagnose if there's a certain MAC / IP address on the local network that's spewing out loads of data (i.e. possible infection)?

Best tool is http://www.wireshark.org/ but it will require some learning, it doesn't really have a "this is your problem" interface ... There's loads of tutorials out there though.... You can also upload your scans to http://www.cloudshark.org/ to share with other people/peers.

Packets never lie, Wireshark reveals everything. The placement is very important on where to do the capture.
