Hi Experts,
I would like to ask for assistance. I've been troubleshooting this for weeks already, but can't resolve the issue. When I try to join a client to the domain, the following prompts:
An Active Directory Domain Controller (AD DC) for the domain "CONTOSO.COM" could not be contacted.
Ensure that the domain name is typed correctly.
If the name is correct, click Details for troubleshooting information.
Details:
The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "CONTOSO.COM":
The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)
The query was for the SRV record for _ldap._tcp.dc._msdcs.CONTOSO.COM
Common causes of this error include the following:
- The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer
is configured to use DNS servers with the following IP addresses:
192.168.0.5
- One or more of the following zones do not include delegation to its child zone:
CONTOSO.COM
COM
. (the root zone)

Some information:
- It is the only Domain Controller on our infrastructure.
- The error occurs when trying to join a client that is not on the same VLAN as the servers.
- Incredibly, i am able to re-join a client after 5:00 PM (which is after office hours), regardless of the VLAN designation. But the following day, the issue will occur again.
- I also tried visiting eventwr.msc, and was also able to address issues already. Event ID 4000 and 4007
- I also performed dcdiag /test:dns:
