I am working on a new install. I set the IP address, sub, gw and DNS servers. Performed an upgrade to 9.0. Now I'm trying to change the IP address to work on the customers network and ESM will not allow me to change it. Also the DNS field below the ip properties is gone. I can click "change" and the window opens but the only setting it will allow me to change is the VLAN. Any one else have this trouble? TIA
