Can't see internet

Periodically one of the computers on my LAN will stop connecting. I can
fix it by hard coding an IP address so that it sees other computers in my
home via my router. But I don't know what DSN to put in when I do this.

If I have it go automatically, it tells me another computer is using that
address.

After my LAN is connected, my Internet connection is not connected. I can
see my other computers, and I am not finding any settings different (other
than the other computers get their TCP/IP address & DSN address
automatically.

What am I missing? I suspect I need a DSN address, as this is checked
off.

Check the ethernet cable of the problem machine with a LAN tester if
possible, or swap it out with one of the other know good cables and
see if the connection settles down.
Also you can open a cmd window and enter "ipconfig /all " on the
system that runs the internet connection.
You want to know what the IP address, subnet mask and default
gateway settings are
EG:

C:\Documents and Settings\Li'l Roberto>ipconfig /all

Make sure all systems have the same IP range [10.0.0.1~ 255 or
whatever] and have the correct subnet mask [255.0.0.0 in this
case], and that the default gateway and DHCP server
[router]address's are the same for the internet connection to work.

I have had success just re running the network wiz on the main
system and creating the setup diskette to run on the other systems
in situations such as yours.

I found an old post with the DNS I needed, so I plugged it in. It works
now. I don't know why I need it hard coded sometimes, but from now on, I
will leave TCP/IP and DNS hard coded.
