We have a dhcp server, Windows 2008 R2. We are using server option 135 with a listing of 3 domains (1 parent, 2 child). When I release and renew dhcp on the client systems, it is not picking up the 1 child domain DNS I just added into the list (it's 2nd in the search order listing). The local systems are dhcp, no GPO setup for DNS suffix, no local policies setup on the clients, and networking adapter is set to "append primary and connection specific dns suffixes" and "append parent suffixes of the primary DNS suffix"
I've stopped/restarted dhcp, I've rebooted client, I've /release /renewed client and still not picking up correct suffix order. Any suggestions?
