Our DNS service is being transferred from our Operations team to the Network team.
One of the options they want to explore is to place a load balancer in front of the Windows 2008 R2 AD integrated DNS servers to load balance traffic from the clients, giving flexibility to the back end servers if we ever move them.
Any thoughts on this approach? It seems more complicated but I can’t see a reason why it shouldn’t work, or be considered

Load balancers in front of DC\DNS servers

In my experience there are no big caveats when implementing a Load Balancer for DNS and LDAPS. Do make sure that this Load Balancer is setup redundantly to prevent a single point of failure. 1 annoying thing is that you never know where DNS records are updated, so you will need to rely on automatic replication heavily ;).
All I see here is adding a single point of failure. Don't see the value in what they are doing at all.
I see this done all the time in the Citrix related projects I have done and do. Customer puts an HA pair of NetScalers in front of the infrastructure and load balances various Citrix components along with DNS. No single point of failure as long as what you use for the load balancing is not a single device.
