This is for a small network. We are switching our ISP with a new set of public Static IPs. We have a dual port server. One connected to the WAN side Router and another configured for LAN. This server(windows 2003) has ISA server and exchange server(2003) installed and also acting as DMC/DNS/DHCP. My question is what devices/settings need to be changed with the new IP settings.
I understand, I need to configure WAN interface of the server. Is there anything needs to done to the ISA settings and/or exchange setting?
