If a company has a web site called www.xyz.com, to handle demand, has
setup 3 web servers with identical content for the web site (WebServer1,
WebServer2 and WebServer3). There will be 3 DNS records for the IP
address of each server.

When a client sends a query to the DNS server to resolve www.xyz.com the
DNS server sends back the IP address of all 3 records with Webserver1 at
the top of the list, WebServer2 in the middle and WebServer3 at the
bottom.

If round robin is enabled on the DNS server, the next request for
www.xyz.com that the DNS server receives it will send all 3 records
again but this time will place WebServer3 at the top of the list,
Webserver1 in the middle and WebsServer2 at the bottom (rotating the
record at the top of the list for the last request to the bottom). This
provides a form of load balancing as the clients try to contact the
server at the top of the list first.

Round Robin can be enabled by using the DNS manager console. It is
configured at server level and can be set by checking the Round Robin
box on the Advanced tab of the Properties of your DNS server.
