We have two DNS (server 2008) servers and one DHCP (2008) server. Many of our DHCP clients are getting leases just fine but not being registered to the DNS servers.
Server A - Primary DNS server
Server B - Secondary DNS server and DHCP server
Server B has scope options 006 for DNS servers and 015 for DNS Domain Name.
Reboot doesn't work, repair on the NIC won't register nor will a ipconfig /registerdns.
Now the only way we can get these to register is to enable "Use this connection's DNS suffix in DNS registration" and force DNS register by a repair or ipconfig /registerdns. Now I thought that's what the scope option 015 was for but I must be missing something here.
Please let me know what I'm missing. If nothing and this must be checked how would I go about enabling a GPO for the "Use this connection's DNS suffix in DNS registration" option on the clients?
