Windows Server DNS with non-Windows (Linux, Mac) Computers

How do I get my non-Windows (Linux, Mac) computers to properly register their IP address into my DNS server?

Server Name: AD1 OS: Windows Server 2008 R2 Roles: DNS, AD, DHCP

DNS SETTINGS
Dynamic Updates: Secure Only

DHCP SETTINGS
Checked - Enable DNS dynamic updates according to the settings below. Always dynamically update DNS records.

Checked - Discard A and PTR records when lease is deleted

Disabled - Name Protection

I've tried setting a DNS dynamic update registration credential user and then added that user to DNSUpdateProxy.

However, when I connect a Mac/Linux computer to the network, it'll get an IP from the DHCP server, but it will not add it's IP into the DNS. I cannot add these computers to the Windows domain.

I've searched around but can't seem to find a definitive solution. Any ideas?

Thanks,

Michael

DHCP | Expand Server | Right-Click IPv4 | Properties

DNS Tab | Check "Dynamically update DNS records for DHCP clients that do not request updates (for example, clients running Windows NT 4.0)

That was the key to making this work.

I went ahead and set back Dynamic updates to Secure only in the DNS settings and my non-Windows clients are still able to update the DNS records. I also removed the created user "DNS dynamic update registration credential user" and it's still working.

Here is what my log looks like:

30,04/30/14,15:17:20,DNS Update Request,58.3.10.10,m-pro.domain.local,, 11,04/30/14,15:17:20,Renew,10.10.3.58,m-pro.domain.local,28GFE112B263, 32,04/30/14,15:17:20,DNS Update Successful,10.10.3.58,m-pro.domain.local,,

I'm thinking that this setting is your problem as they can't do a secure update in their present state

But by configuring DNS dynamic update registration credential user and then added that user to DNSUpdateProxy, doesn't it solve it?

I will switch to secure and non-secure just to see if it fixes the problem.
