Can't connect workstation to domain.

Question

Hello,

I'm currently trying to set up a ADDS network for the company i work for (I've not done anything like this previously). I've followed the documentation and guides to set this up, However, when i go to try to add a test-workstation to the domain the same way i was told to join the VM server to the domain (see below).

File explorer -> Right-click This PC -> Properties -> Change settings (Under computer name section) -> Change (Computer name tab) -> Finally, Member of - Domain.

When i try to do this, it gives me a mix of two errors.

DNS Name does not exist (error code 0x0000232b) & Timeout (error code 0x000005B4 ERROR_TIMEOUT)

I've tried to ping the domain name = Timeout (Same as the IP it's connected to), I've tried to use tracert also times out. I can connect to the VM perfectly fine without any problems, from any computer. but when i'm trying to join another one to the domain it doesn't seem to want to work.

On Azure i've tried to test the connection, but it keeps telling me that the Default_DenyAllInbound rule stops it from connecting, I've added rules on there to see if i can add the IP range on which the computer is on to join but to no avail.

I also know that there is another way of adding a computer to the domain, (Manage accounts -> Access work or school -> Connect) but when i've done that option and after leaving it to sync the computer over it doesn't show up anywhere in GPMC or Administrative centre on the VM server.

Answer 1

I'd check the domain controller and problem member both have the static ip address of DC listed for DNS and no others such as router or public DNS

Answer 2

Is this workstation in Azure?

If so has the Domains DNS servers been specified in the DNS Servers list on the Vnet the workstation is connected to?

Answer 3

To join a AD domain you will have to have the DNS server setting so that it uses a DNS server that contains the zone file (or a copy of the zonefile) for the AD domain. You seem to have tried that but there is no connectivity between the WS and DNS server, which suggests it is a networking issue.

We dont really have a full picture of the setup from a networking perspective though which could contain the answer and I suspect it is something to do with that such as trying to connect from outside of azure to a non routable domain/ip or the vnet or azure Vm rules not allowing the correct ports through.

If you could specify where each machine is located (Azure, on premises etc) and what the IP config is for each (IP, netmask and gateway), VNET /subnet info etc

Also confirm if this is an Azure Active Directory Domain Services you are trying to join or if it is an Active Directory domain (setup on a VM in Azure or on premises)

Also, more details about the DNS server and the domain name used - you can disguise this of course but for example if you are using mysite.local or mysite.com.

Finally , if you can also all your NSG rules so we can see them.

Hello Prince,

Please check the DNS server addresses of the workstation and key in the server’s IP address of the ADDS server and after that check your workstation IP address and the network gateway. when all is done ping the network gateway to see if it will reply if it does then you join the domain but it does not you let your network guys check the flow. Thank you
