I have tried using the flushDNS script but it doesn't work. It hangs up on ipconfig /renew, gives me an error, and then completes the rest. The error is "unable to connect to your DHCP server"
The problem is that you have a modem plugged directly into a switch which isn't how it works.
You need to have a router after the modem in order to obtain DHCP IP's "automatic IP assignments" from the router.
If you need to connect more than one machine you need to either use a router or ICS "internet connection sharing" which has limited use and reliability and requires that you have a PCI network adaptor. In most every case using a router is the best way to go here.
