dns round robin

Jeremy · Post by **Jeremy** » Sat Jun 19, 2004 11:56 am

if two servers are set up to balance load using round robin, will the dns server be able to fall back onto only server 1 if server 2 goes offline, or is the process passive and leave every other user with a server error as they are referred to the offline server?

thanks,
Jeremy

The DNS servers should fail over, the clients will if they are configured with both the primary and secondary DNS server addresses. If you are using Active Directory there is a setting and I can't recall exactly where, but it has to do with the client resolving DNS to three options. They are roughly;
Use Primary Domain Controller
Use from Snap-In
Use any available DC
