I have four computers on my network, and an Xbox 360, all of which plug into my Comcast router in the following fashion:
Comcast plugs into the router box. Port three of the router goes to a small web server I have running, and port two runs to the family computer. Port one runs to an Ethernet switch upstairs which supplies Internet to an IBM Thinkcentre, the Xbox, and a custom build known internally as "X".
The problem lies in X, as when it is inserted into the network on the switch, it essentially assigns the IP addresses for the IBM and the Xbox. When its off, they lose network status completely and when then ipconfig /release ipconfig /renew
commands are run on the IBM, it returns a self-assigned IP address.
My question, in short, is what I should do to allow the other computers on the switch, and Xbox respectively, to have Internet when X is turned off. I tried setting static IPs for X and the IBM, but that didn't do anything.
