A small background before my question :) -
I had a need to create a load balance service name between all the domain controllers, i know i could use the default domain name instead, but it had connections to other servers except for the domain controllers.
since i can't create the same multiple dns host to multiple servers i created a new subdomain and had all the domain controller's IP name SAME AS PARENT...so all would get the same DNS name of the new subdomain, hence creating a DNS Load Balance.
Here's my question though, how does it work? is it round robin? who answers first? the dc the computer is connected to or the DNS the computer is connected to?
AND the most important factor what if one of the domain controllers isn't available, will the be a timeout? or will the query never reach it in the first place?
