Guys, I am with the following scenario: I have a router with two WAN links, each link comes from a different ISP, and corresponding IP. My DNS is external. I have a site that is behind the router, eg.: www.empresa.com. I configured the external DNS to redirect the two IPs for www.empresa.com in ROUNDROBIN. However, when a link is offline, the ROUND ROBIN continues to send requeststo that IP. How can I work with two IPs pointing to my WWW with detection of Falls link?Se foi til marca como resposta! _________________________________________________ Rafael Bernardes - It Hero 2009 Award Microsoft Certified Technology Specialist rafael@bernardes.org http://blog.bernardes.org 21 8162-3956 21 7894-5536

Hi Rafael, Thanks for posting here. I agree that you may consider deploying dedicate device in this scenario since round robin is not a professional solution for failover. NLB is one of solution you may take look: Network Load Balancing http://technet.microsoft.com/en-us/library/cc732855(WS.10).aspx For more information please refer to the great article below: High-Availability System Architecture http://technet.microsoft.com/en-us/library/cc750543.aspx Thanks.
