DNS Round Robin and Load balancing

[Guest]

Hi any suggestion on my setup, Im running windows 2003 dns, i got a zone
xxx.com which is configure as Primary zone, I put 3 A record with name
server.xxx.com pointing to 3 different IP address, if i send ping on the
server.xxx.com and replys on IP one, and its always responsing on same IP,
but if i use active directory integrated zone and send ping to
server.xxx.com, it randomly replys all 3 IP, my questions is it possible to
have randomly reply using primary zone.


Thanks

Turn off "Enable netmask ordering" set the TTL on all the A records to 0 so
that the client doesn't cache the records.

0:1:0:0 is one hour. You don't need to change the default, only the TTL on
these records. Default TTL is used for all new records and for NXDOMAIN
negative cache TTL.

0:1:0:0 is one hour. You don't need to change the default, only the TTL on
these records. Default TTL is used for all new records and for NXDOMAIN
negative cache TTL.

Another fix is to have two clients pinging the address one after the
other. This will prove the DNS round-robin is working.
