Windows 2003 functional level domain which includes... 2 windows 2008 Domain Controllers with integrated DNS serves, one of the 2 servers is a RODC. DHCP is giving our both IP address of DNS servers.
my question - how do I setup the DNS to roll over when one server is unavailable? Right now the first DNS server in the domain is acting like a master/primary. When I reboot the DC with the FMSO roles, (first DC), no one can log in and DNS goes completely down until the server comes back up.
My 2nd DC doesn't do anything i would expect.
Seems I remember that there is a setting that I can change to set a timeout of how long the first DC can be down before the 2nd DC will take over. Anyone remember anything like this?
It may be that I'm not following best practices at all, although I thought I was following them when it came to designing my AD and DNS.
