Network droping after 10 minutes

I have two old win 2000 servers that have been running fine, lately I added a
new win 2003 server to the network and I am having connection issues.
I have a cable modem hooked to the internet. I can connect to the internet
and other network computers fine as long as the 2000 servers are not
connected, if they are connected the whole network goes off line, can't
access any internet sites, can't even access the cable modem at 10.1.10.1.
If I reboot one of the 2000 servers and connect it to the network, everything
will be fine for about 10 minutes, then the whole network drops out again.
I am not a network guy, but know a little about it. Has anyone every
experienced or know what could cause this type of problems.

Thanks in advanced.

You did not provide enough information to diagnose this.

When this issue occurs, how did you determine that the cable modem cannot be
accessed? Did you perform pings?

1 What type of server is the 2003 machine, a DC, member server, or SBS?
2. Does it have DHCP running on it?
3. What are you using for DNS address in IP properties?
4. What machine is the DHCP server?
5. Is this an AD network? If so, describe each server's role please.


Please provide an unedited ipconfig /all from the two 2000 machines and the
2003 machine. Please do not edit the results or it will lead to additional
guessing on our part.

Thank you,
