We are running Windows 2003 AD DNS - domain is company.com
We have a web application that we want to be accessed on http://webapp.company.com
The actual application will be running on two Windows 2003 Servers - server1.company.com and server2.company.com
Does anyone know how I can make "webapp.company.com" point to both servers (for load balancing)?
i. Create an A record for 'webapp' have it point to the IP addresses of server1 and server2
ii. Create a CNAME entry of 'webapp' for the A records of server1 and server2?
iii. Something else?
Also - do I need to make the PTR records point back to 'webapp'?
Secondly, I would also like to implement some sort of fault tolerance here. So that if, say, server1 was down, all requests would go to server2.
iv. Am I correct in thinking that the solution I implemented for DNS load balancing above would not help? Even if a server was down, DNS would still return either address for requests?
v. What I need is a load balancer (Cisco etc)?
