I have added a new computer (lets call it LD) to the work network (windows 2003) and it is the 9th computer on this network. Problem I'm having is that once it's connected I can see / access the network but it will not connect to the internet via LAN, however, I can connect via wifi. Now this is where it gets tricky...If I turn off 1 particular computer on the network (lets call it AB) - I can then get the LD computer to connect to the internet via LAN but then when I boot AB back up it is now connected to the network but has no Internet accessibility.
Things I have tried:
1. Reset the modem and router
2. Called our ISP and had them send a refresh signal
3. Moved the plugs on the switch to make sure one hadn't gone bad
4. Checked to make sure both computers are set to automatically obtain IP
