I am working on the following setup. Phone Line > Modem > Server > Switch > 7 Workstations The server is running Windows 2003 and has two ethernet ports, one to accept the Modem (incoming), the other to output to the Switch (outgoing) Well the other day I changed our internet provider and got a new modem. But the internet does not work anymore. The internet works fine when connecting a Workstation directly to the new modem, but when you connect it through the server in the usual way something is blocking access. I think that Win 2003 is set up in a secure fashion and something needs to be changed. IP settings? Please give me some ideas of where to start. Thanks
