Thanks Graham, and everyone else who has offered suggestions thus far. The network is a predominately Windows environment for the workstations. Linux is used for the firewall (IPCop), and a web gateway (using Apache with virtual hosts). (The Telus people suggested the IPCop firewall was to blame... I don't believe them.. <grins>)
We've proven with at least some degree of certainty that the problem IS an internal issue. (by connecting a laptop to the DSL modem directly - it did not suffer the same problems we've been seeing). The network cables probably could use a bit of tidying, but they all seem good. When this problem comes up, it seems to be the entire network all at once, but this is hard to confirm as the workstations are scattered across two buildings - by the time we get over to the other building (or pickup the phone), the problem could go away for a while. The network has a mix of network speeds - 10, 100, and 1000BaseT. The Gigabit is used to connect the three main switches involved. DNS is currently provided by the IPCop firewall which is seeing between 0 and 5 percent cpu utilization. The firewall also has sufficient drive space available. I think the problem is one of the 3Com switches (managed SuperStack switch). We missed it earlier, but for every port that has a cable plugged in, we are seeing a steady rythmic pulse of the activity lights - not usual activity behavior. Also, we are seeing a lot of Spanning Tree activity with Ethereal. This weekend we will be taking the network offline to run more detailed tests. If you'd like, I'll let you know when/if we find the root cause of the problem.
