I have a Linux host in my SBS2008 domain that get its DHCP address from the SBS2008 server (see underlined entry in DHCP image). However, it does not put the DHCP IP into the DNS list so other hosts cannot get to it (see DNS image). I know I can put a static IP into the DNS list for this host, but I'd rather use DHCP. For DHCP > IPv4 Properties > DNS, I have "Enable DNS dynamic updates according to the settings below:", "Always dynamically update DNS A and PTR records", "Discard A and PTR records when lease is deleted", and "Dynamically update DNS A and PTR records for DHCP clients that do not request updates (for example, clients running Windows NT 4.0)". I also have DHCP > IPv4 Properties > Advanced > Credentials, set with the administrator ID and password.
What do I need to do to get this host into DNS (host 192.168.0.50 is another Linux host showing up in the DHCP leases, but not in the DNS)
