Alright, there have been some outages with our cable provider the past few days. Today I get woke up by my dad bitching that he cant get online. I look @ the modem, its connected, look at the router, 3 of 4 lights are on, which is correct because i didnt have my lappy plugged in for #4, so it sees all 3 computers that are currently hooked up. I look at his computer name and network group, all are good. I can access the internet, the other computer can access the internet, I just had my girlfriends lappy hooked up to the cable that my lappy plugs in to and she got on the web fine, but his computer cant. All of my computers run Windows 2000 Pro. I checked the router settings and even reset it and configured it all over again, still nothing. the DHCP routing setting is enabled @ 192.168.1.100, with 50 users. The DHCP table shows my computer, my laptop, and a blank name with a MAC address which I am assuming is my the other desktop (its not logged in to Windows). Im stumped. This happened before and I got it working, but this time its got me. Anything I missed or need to try again? Thanks in advance.
