New 2003 Server - Cannot Reach Outside Network

Hi, I'm pretty new to Server 2003 (but pretty experienced
at NT4 & 2000). I'd appreciate anybody's help on this
mystery:

I recently had to reinstall our Windows 2003 server due
to instability from a suspected power supply failure and
subsequent hardware replacement. I reinstalled the server
successfully, and the network interface is behaving fine.
I am able to get connectivity (both ping and network
browse) on my internal network, but unable to reach my
gateway or the internet.

I am behind a Sonicwall SoHo3 firewall. However, I have
no special rules, routing or filtering. I have tried
static and dynamic IP addresses to no avail. It is not a
hardware issue since all other devices on the network can
get thru the firewall. I'm wondering whether there is a
security feature in 2003 that is preventing communication
from/to any NAT device. Also, I ensured that "Internet
Connection Firewall" is disabled.

Thank you.

assuming the server comes with two NICs and the NAT is enabled, check the
NAT settings.

Problem Solved: The firewall / router was out of node
licenses, since we were at the limit (10) the new IP of
the server was blocked. Thanks all for your help.
