Hi,

DNS Question (running Windows 2000 SP4 server)

We have two web servers on different backbones managed by
different ISPs (one domestic and one international for
external clients). I would like to configure DNS records
for these two servers so that when a user types our URL
into their browser, the route used is to whichever server
is 'nearest' or has the shortest path to the browser. The
reasons are both load sharing + one of
Is it good enough to add two A records to the domain name,
each pointing to different servers? Most local ISPs are
interconnected. Does this mean that the route used to the
web server for local users will be the local server?

What happens if one of the servers goes down? Will
connections automatically be routed to the other server
(that's what i want)?

Thanks

For your "local" users, point them to the private IP or the closes public IP
to them. Do this with the IP you add to the local zone or zone local users
use.

Not really. IE, I have seen, will try the next server if the first in the
list can not be reached or does not respond, but I don't know if this is
true all the time under all circumstances. Moreover, many INET apps or
other do not do this rollover to the next server in the A list.
