Broadcast domain. > > Also, would the speed of the wire make a difference ? Theoretically it could make matters worse. Devices could send broadcasts even faster on 100 Mbps than they can on 10 Mbps. Also devices can send requests to servers more quickly and servers can get overloaded. That's in theory, but may not apply to your situation. > > I'm asking 'cos I've just joined a new company.

So you're talking about them all being in one broadcast domain. That's probably better than them being all in one collision domain. But it could be marginal. Remember the issue with broadcasts is that that they disturb the CPU on each machine in the broadcast domain. This gets especially ugly with older PCs with slow CPUs. You should gather some more info about the CPUs in use. > Ping packets (indeed > all types of packets) are just "disappearing" as are mapped > drives.

What kind of stats do you see with show interface, etc. With troubleshooting, it's best to use a bottom-up approach. Is cabling OK? Are there CRC errors? Have you checked data link layer issues such a duplex mismatch? What is the broadcast rate? Subnetting will probably help, but I would suggest gathering more facts first.
