Network configuration problem

Hi,

I have what is probably a fairly basic problem.

I have a win2k3 server standard, with two nics, one external and one internal.

The external nic connects to a wireless router. The router address is
192.168.0.1. The ip address for the external

nic is 192.168.0.2.

DHCP is enabled on the server. The internal nic's ip address is 192.168.16.2.

I can ping the server (192.168.16.2) from a xp professional laptop connected
to a switch from the server's internal nic. I cannot, however, ping the
laptop (192.168.16.11) from the server.

Moreover, I cannot connect to the internet from either the server or the
laptop with my current configuration. Although, I can establish a wireless
connection to the internet from the laptop.

I am able to NET USE to the server from the laptop. The laptop is not
joined to the domain.

Questions:
*why can I not establish an internet connection from the server? What do I
need to do differently?
*why can't I ping the laptop from the server?

Thanks!

We have many issues here.

1. To troubleshooting the internet access from the server, ping the router 192.168.0.1 first. If you can ping it, the ping 4.2.2.1, if you can ping it, ping yahoo.com
post back with the result.
2. For the computers in 192.168.16.x subnet, make sure the IP routiing i snabled.

How to troubleshoot the Internet Access issues
You just setup a network and all networking computers can see each other. However, you have one of some following issues:

1. None of the networking computers can access the Internet.
2. Only one of two computers can access the Internet.
3. Cannot access some web sites.

Questions:

*why can't I ping the laptop from the server?

Thanks!

Argh, I cannot ping the router. Ping 192.168.0.1 fails.

For ensuring that IP routing is enabled in the 192.168.16.x subnet, what do
I need to do?

Right, none of the networking computers can access the internet via the
wired LAN.

Thank you

I removed the Remote Access/VPN Server role from the server and am now able
to access the internet. I can ping the router, 4.2.2.1, and yahoo.com from
the server.

I can also ping the server's local address (192.168.16.2) from the laptop
(192.168.16.11). I cannot ping the server's external nic address
(192.168.0.2) from the laptop, nor can I ping the router (192.168.0.1) from
the laptop.

I cannot ping the laptop (192.168.16.11) from the server.

Nor can I get to the internet from my laptop. Note: I have not added joined
them to the domain.

The original issue may be some things to do with NAT. The laptop issue now is no default gateway.

What should the default gateway be for the internal LAN?

When I set the default gateway on the server to the internal nic, I get a
warning that "multiple default gateways are intended to provide redundancy to
a single network (such as an intranet or the Internet). They will not
function properly when the gateways are on the separate, disjoint networks
(such as one on your intranet and one on the Internet). Do you want to save
this configuration? {Yes | No}?"

When I set the default gateway to the router, I get the warning "The default
gateway is not on the same network segment (subnet) that is defined by the IP
address and subnet mask. Do you want to save this configuration? {Yes | No}?"

Thanks
