Tough connection problem

[Paul Mazaika]

The basic problem is that I can connect to my local network, but cant
get outside of it to the internet. I can ping local machines but cant
ping the cable modem. Other machines on the network can.
I replaced the NIC card and associated drivers. I deleted TCP/IP,
Client for MS Networks and File&Printer sharing and reinstalled.
Ran a system scan with Nortons and AdAware.
Ran SFC and replaced several files.
Connected the machine directly to the cable modem with no luck.
Tried several different cables. Direct to the cable modem. No luck.
Other machines get out just fine. IP address, Subnet mask, DNS server
numbers all ok.
One other interesting note, the machine connects to the local network
at 10Mbps even though it is a 10/100 card. (Set to autosense) If I
change the setting to connect at 100, it does, but when left to
autosense, it connects at 10 Mbps.
Running Win2K.
Didnt really do anything on the machine from the time it worked to the
time it didnt. Just stopped working.
I am at a loss. Any help would be appreciated. Thanks
Paul

- Turn off your internal firewalls during testing, especially those
that are integrated with your virus scanner.
- Force the machine to 10 MBits/s half duplex during testing.
- Always ping by IP address while testing, never by name.
- Pay attention to your cabling. Some routers require a cross-over
CAT5 cable.
- Build things up one step at a time, e.g. by doing this:
1. Connect the problem machine directly to a laptop, using
a cross-over cable, then try to ping in both directions.
2. Connect the laptop to the cable modem and ping it.
3. Using the same cable, connect the problem PC to
the cable modem and ping it.
While performing these tests, make the network adapter
status indicator visible in the System Tray and watch the
transmitting/receiving byte counters as you ping. It will
tell you plenty.
