can Network Load Balancing cluster help failover??

can Network Load Balancing cluster help failover??
like if I have a website on two webserver and make sure that if there is a failure of a single server, the Web site still can be accessed.
do I have to install failover cluster too, just NLB would not work, right?
Thank you

is it just for website cuz it is static??
but dns would use round robin, if one server down, it would still get to the down server, isn't it?
thanks

The answer is no if it was static websites. NLB is the only feature you need to install and it will handle the website correctly if one web server fails.

A Fail over cluster doesn't need to be installed in this case.

DNS Round Robin doesn't have the "Smarts" that NLB has with it's ability to detect if one web server has failed. So if you only use DNS Round Robin, it will still attempt to push requests to the failed web server.

Hope this assists.
