I work at a small company and use an older computer running Windows 98 as the DNS, DNCP server. I don't know much about this at all. It loads NetBSD 1.5.3 and uses the xterm terminal. Starting about a month ago, about once per day, or every other day, the internet stops working. I go to the server room, and on the screen of this computer it says "NIC Memory Corrupt - Invalid Packet Length." Then several lines of "Message Repeated x times". I hit the reset button on the computer, it reboots, and everything works fine until it happens again the next day or so, and the pattern continues. It is a short term solution to reboot, but how can I fix it permanently?
