Question about creating a DNS load balance between domain controllers
Hi,
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.
So....
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?

If all your DC's are running DNS then all you need to do is list all of he DC's IP addresses in the NIC cards DNS settings on all machines. Windows will take care of the rest. No need for ANY load balancing, round robbins or square ones.

I didn't understand how this will create a load balance?
my need is to ping a name for example (dns.company.com) and have a redundancy (perhaps i should have used that therm instead of the load balance since it explains my needs better) between all domain controllers.

Can you explain EXACTLY what it is you want to do and why?

I have several applications that connect to Active Directory using LDAP directly to a Domain controller server, i don't want to give them the name of 1 domain controller since if it's down then the service is down, so....i want to create a DNS alias name to hold behind it all available DC's

I haven't had any problems but yes the original DOMAINNAME.COM is full with other IP addresses that are not DC's, some are even external IP's i need to figure out how come it happened.
