Ok, when our lan switched to DHCP, and my linux boxes dropped off the network, it is because the DNS wasn't set correctly. Got the DNS set now, and they are showing up in my Exceed XDMCP broadcast box however, i now have another problem. They access the internet. I don't want them to. HOw can I set them to stay within our internal network only? we have a router, firewall (cisco) but I don't want anyone to be able to access them from outside our internal network.
