Originally everything worked just fine. Then, about October it spontaneously started losing its ability to talk to the internet, and the other computers in our office lan (peer, not DNS or DHCP) couldn't see the server. Solution: reboot the server. Problem: this happens every 2 days, like clockwork. Any ideas? I am using the router as the DHCP, and that has worked fine for over a decade. Not a problem with the router, I believe, because it goes away when the server is rebooted. Presto! everybody can talk to the server again, and it can get on the internet, no problem. for 2 more days... My best guess is that something happened during a software update, but I can't pin it down. ideas? suggestions?. Thanks! John Morris
