I have a small LAN of web servers using Windows 2000 DNS. The servers
can see any URL I type in except for 1. The URL has a public IP, and I
can hit it from outside of this LAN. There is nothing inbetween that
would prevent it. Pinging the URL, or the FQDN time out. Any help
troubleshooting this woudl be much appriciated.
 
You say pinging timeouts, but it is accessible outside your LAN. So you have
that IP outside your LAN, right? Then you have to check if your resolved IP
is correct or not. If it is correct, then you simply tracert and see where is
the problem.

BR,

looks like it was a problem at the other end ... before I could even
try a tracert, it started to resolve.

If you are trying to get to an internal webserver on your private IP range
behind a NAT device by using your NAT device's WAN IP, then it cannot do
that. THat is a limitation of NAT, it will not port remap an internal
request to it's external interface and back in again to the private IP. It
doesn't matter what name brand NAT. You'll need to provide the private IP in
DNS. Now if DNS is hosting this zone for external use with the WAN IP of the
NAT, then the recommendation is to have a separate DNS for internal use,
create the zone on this server, and only provide the private IPs, and have
the internal machines only use this DNS server.
