Workstation A records missing from DNS server

I have recently noticed that our DNS server has not registered a number of computers on our network.
 
I can successfully ping these workstations fine. NSLOOKUP (workstation name) on the DNS server and from other computers on the network is unsuccessful. Then I noticed that the A records are missing from the DNS server.
 
These computers also exist in Active Directory.
 
Any reason to why these workstation name A record are not showing up on the DNS server?

Since you have not shared specific details about your network environment, I am assuming you have a DHCP Server to allocate IP Address to DHCP Clients across the network.

In case DHCP Server applies to your environment please check to see if your DHCP Server is configured to register DNS entries for clients?

Steps to validate:

1. Start DHCP Server Management Console
2. Right Click on the DHCP Server Name and Choose Properties
3. Click and DNS Tab and check all are enabled as shown on the image given below:

 Configure DHCP Server to automatically update DNS Server

In case you are using non-dhcp windows clients, please enable DNS Server registration by following the steps given below:
1. Open Network Adapter properties,
2. Open Internet Protocol or Internet Protocol Version 4 properties, by double clicking.
3. Choose Advancedin the IP Address properties Dialog
IP Address Configuration Window4. Choose the DNS Tab, and enable "Register this connection's address in DNS
 Enable Register this connection's addresses in DNS

Hope this helps!

Also check (on advanced tab in forst screenshot) that DHCP server has credentials to update DNS.
Can you check if the A records appear after running 'ipconfig /registerdns' on the clients?

also check if you have secure or nonsecure updates allowed on your DNS server, as secure only can prevent workstations from updating their own DNS records.

DHCP should only update DNS for machines that cannot do it themselves, so most XP > win 7 pcs shouldnt have a problem regardless of DHCP > dns settings. It's still worth checking it though, as you should have the DNS update facility activated as many networks contain devices that cannot update their own DNS (mobile phones etc)

Umm do you recommend secure or nonsecure on the DNS server?

If your dns port is open to the internet always go secure.
If its internal only nonsecure is fine.

I would second @totallytonto on when to decide going to secure DNS.
