DNS GlobalNames

Globalnames allow a domain name as short as .apple, .xbox and .intranet to be used. This video looks at how to configure Windows DNS to use names like these on your internal network and also how global names will be used in the future on the internet.

I don't ever comment but I wanted to thank you for these videos. I'm currently working on my MCSA for 2012 R2 and just passed the 410 test.

I've been watching your videos for a while and they always clears up whatever has me confused after reading material from a book.

Thanks again!

Thanks for the explanation it was great.

For those of you studying for the MCSA

Instead of using dnscmd.exe you can use powershell to enable the same thing.

Step1 - Enable the DNS Server for Single-label quires.
(Run on the DNS Server)
Set-DNSServerGlobalNameZone -Enable $True -Passthru

Step2 - Create a Primary DNS Zone AD Integrated with dynamic updates turned off. Replicate Forest Wide. Name "GlobalNames"
Add-DNsServerPrimaryZone -Name "GlobalNames" -ReplicationScope "Forest" -PassThru

Step3 - Add a CNAME record for each host you wish to provide a single-label name for.
-Name "TEST" -HostNameAlias "TestSRV01.Contoso.com" -ZoneName "GlobalNames"

in my test lab I created cname for my FQDN, inside the Forward lookup zone, which is working fine without creating GlobalName zone, I'm now confused I think I missed something to understand, why we need GlobalName if the cname do the job ?? .. could you please explain a bit morethanks a lot for your all great videos.regards

Learned that the default user group is named public. Moreover, a default domain is assumed to be a group, when no domain is created and AD is not used on a stand alone server. I placed computers in the group public. I added cnames for the computers in the globalnames zone. The config seems to meet the single name design .. Used WINS and RWINS. in dns as weLL

A few questions. In what order are these globalnames resolved in relation to the other zones. Let's say intranet in itfreetraining.local points to svr2 and in globalnames to svr1. The client computer is a member of the itfreetraining.local domein. When it tries to ping 'intranet' which IP is returned? Can the order be changes (e.g. can globalnames override suffix search).

My last question is not about GlobalNames, but is about the remark that dynamic updates should be disabled. Does this implies that dynamic updates are by default enabled in Windows DNS?

On my DNS server I need to specify which server is allowed to make dynamic dns updates. On my network that is only one server, the DHCP server. I've also setup DNSSEC for authentication and verification. I once had a 'guest' on the wifi network that was trying to spoof the IP of the DHCP server in order to make changes to the DNS server. My firewall was able to stop the attack as the IP was coming from the wrong network interface (eth2 instead of eth0)..
