It doesn’t matter now, because you were brought here to find out what to do with it. It stands for “Fully Qualified Domain Name.” It is multi-level, or hierarchal, such as: domain.comdomain.netdomain.localchilddomainname.domain.localetc What is a Single Label DNS Domain name? The Root domain name, such as com, edu, net, etc, is also known as the TLD (Tope Level Domain name).
I hope you find this blog informative on this issue and what to do about it. The name is reminiscent of the legacy style NT4 domain Net BIOS domain names, such as: DOMAINCORPCOMPANYNAMEetc Unfortunately, since this does not work with DNS, and Active Directory relies on DNS, therefore, it does not work with Active Directory. Basically you can look at a DNS domain name as having multiple levels separated by periods.
Sbs 2016 dns not updating
If you’re not familiar with DHCP settings though, I suggest you leave it the way it was.
Man of us are now familiar with AD’s naming convention, and have more than likely renamed or rebuilt their AD domains.
There is a similar service on the SBS server that will broadcast when it’s IP address changes, the clients on the network pick this up and update DNS, the clients off the network will just re-do the process above to get the right IP address.
A side-effect/pro of this design over the SBS 2008 or 2011 Standard design is that if the server is down for patching (we all know how long those reboots take), or another reason, the client will revert back to the DHCP assigned address after a short period of time and can continue to resolve the Internet until the server comes back online. SBS 2011 Essentials is still a full blow copy of server, and all the power that you’re familiar with is there.
The minimal requirment for an FQDN domain name, such as microsoft.com, is two levels.
