Server 2008R2 - Resolving issue: _ldap._tcp.pdc._msdcs.infosys.local.

Hi Experts-- I have a DNS issue. Brand new server. Windows Server 2008R2. All security updates done. Domain name: infosys -- Under Server Manager, the DNS Server role there are several of the same errors as shown below. I have double-checked all my settings and followed the recommendations below, but to no avail. When opening Server Manager, the DNS server role still shows these DNS resolving issues below. Any help in pointing me in the right direction would be appreciated. Thanks in advance.

What is the SOA record on your primary domain suffix?

For the first error check this link out:

Primary DNS suffix is: infosys.local

Here's a print screen of the SOA:

Is both the AD DS and DNS has been installed on the same Server.Assume that the issue is that you may have not provided the DNS suffix on the server.On the the network card provide the dns ip as 127.0.0.1 or the server's IP address.

Can you post the result of Ipconfig /all for furthure investigation , if the above not helped to fix the issue.

Ahhh...it was right in front of my face all the time...yes, of course, it should be .2 (the server)---I should have seen that, I guess I was visiting Pluto and not paying attention to the basics! I've changed the primary DNS and all is well except for one error in the "best practices analyzer" as follows---

FYI -- I have listed the loopback IP (127.0.0.1) as the 2nd entry and still get the error below?

Issue:
The network adapter Local Area Connection does not list the loopback IP address as a DNS server, or it is configured as the first entry.

Impact:
If the loopback IP address is the first entry in the list of DNS servers, Active Directory might be unable to find its replication partners.

Resolution:
Configure adapter settings to add the loopback IP address to the list of DNS servers on all active interfaces, but not as the first server in the list
