Win2003 broadband access

[Brian]

Unfortuantly I am posting this on the server 2000,
newsgroup because I was unable to locate a server 2003.
Basically I'm having the simple problem of being unable
to access the internet from my server 2003 system. I have
2 network adapter cards in the server, one to access the
local intranet, the other to access the cable modem. The
NIC attached to the cable modem recieves an IP from the
ISP's DHCP, and appears to be accessing the internet.
According to the ISP the server is connected to the
internet; however, I cannot renew the ip address through
ipconfig /renew; nor can I repair the connection, without
recieving the error message could not complete flushing
the ARP cache. If I ipconfig /remove, and then renew the
ip address from the cable modem, I recieve the ip address
again from the ISP, but still cannot access the internet.
I do have NAT routing enabled, a DHCP, DNS, and domain
controller server systems setup on the 2003 system, and
in fact can see the server from my client computers;
simply none of the computer's can access the ISP
including the server. Any other suggestions would be
appreciated.

Thank you

Try:

1. Start/Connect to/Show all connections. Click Advanced/Advanced
Settings. Make sure that the Local Area Connection for your internal
network is at the top of the binding order.

2. In the TCP/IP properties for the Local Area Connection connected to your
internal network, do NOT configure a default gateway.

3. Make sure your DNS server is listening only on the NIC connected to your
internal network. Your client computers should all be pointing to your
server's IP for DNS. As a result your client computers will not be able to
access the internet unless you configure Forwarders on the DNS server to
point to the IP address of your ISP's DNS server.

However, this should not affect the Server's Internet access. So, on the
server Start/Run cmd ENTER. run ipconfig /all. Note the default gateway
and DNS server IPs on the NIC connected to the Internet. See if you can
ping these addresses.

Thank you for your assistance, the problem was a default gateway was assigned
to the local internal network, once this was removed, and the modem was reset
both the client and server gained access to the internet.
Thanks again
