Richard, Some things to check for is subscribed pages in IE and also Windows Update on the PCs - which I assume are running some form of Windows. Windows Update can check automatically for updates unless you tell it otherwise. Also anti-virus programs can also check automatically for updates. I suspect there is a program somewhere in the background that is doing an auto check for something. One other way to see what it is, setup squid (or similar proxy/cache app) and set the PCs to point to that. Then look at the logs and see what is being requested. (Or, if using IPMASQ on the linux box, enable logging for that, but that could be rather volumous.) Just some thoughts.
