Hi,

We have a 2 server TMG 2010 Array SP2 Rollup5. At the moment we have windows integrated NLB enabled. We are about to disable NLB and implement DNS Round Robin. The DNS servers will have a Host A Record with the FQDN for name of the Array for each array node IP address. I know that with Round Robin enabled (by default) the DNS server will rotate the IP addresses that it provides to clients attempting to resolve the array name, to spread the load evenly across the array servers. The question I have is - is there anything that specifically needs to be done on the TMG servers to compliment the DNS Round Robin process.

many thanks in advance

No you don't need to do anything.

Note that DNS Round Robin will not work as a load balancing mechanism and will not be able to determine the load on each node in the array.

Hi, Thanks for the quick reply,

yes I'm aware that there may be disproportionate loading on each Array server, and also that there will no detection that a node is unavailable.

Thankyou for answering my question

Regards
