hi guys. i am having the same error. what do you mean there is a dns problem? how do i resulve it?
When you add a Server, it has a name.
But to use that name, it needs to go through a Dynamic Name Server, to lookup the proper address.
A computer only understands 01010101010011111010000111010101.....
So a name like: MyServerToBeManaged, although you understand the name, the computer will start doing... nothing! Because it needs this name to be translated into bits, zeros and ones.
To make even this more visuable to a human reader, you get IP Addresses in the sense of
172.22.x.x for a class B network on the Netmask 255.255.0.0 or if you like class A you get 192.168.x.x on the 255.255.255.0
But although the computer can translate Hex into binary automatically, it can't with the names.
Thus you need a server, a dynamic name server, to translate the name for the computer.
I have an easy setup with only 2 AD DC, so I have one as first DNS for the 2nd and the 2nd has the first DNS pointing the first.
i.e. DC 172.22.56.2, router at 172.22.56.1
The other computer on the other subnet is at 172.22.57.2 and it's router at 172.22.57.1
They are bind by oVPN to a class B network.
To make sure they see each other, the first DC has 2 DNS:
172.22.57.2
172.22.56.1
and the 2nd DC has also 2 DNS:
172.22.56.2
172.22.57.1
So both first look for their partner for DNS queries *had to do that to make sure the local.domain.com would be resolved properly, because if you have the routers DNS first, your DC start looking for each other in online DNS resolvers for the WWW, which
you don't want them to!
You first point them to each other, and first if THEY can't resolve it, they look online..
This setup is very bad practice if you have more then 2 DC though, but it's an easy setup for home users.
