I have 2 windows server 2000 systems and about 30 computers. I had an westell modem with a linksys router hooked to it. Now i upgraded to the netopia business router built inside of it. I can configure new modem if i plug into it but when i connect switches to it all of the other computers are still pulling he old default gateway. I have changed the default gateway on servers and still no luck. Can anyone help.
