An 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 "unitytechlab.com".

The error was: "No records found for given DNS query."
(error code 0x0000251D DNS_INFO_NO_RECORDS)

The query was for the SRV record for _ldap._tcp.dc._msdcs.unitytechlab.com

This clearly is a DNS issue, can you nslookup the DNS records from your device? Where is the source device and does it have a direct connectivity to the ADDS instance?

Hi,

Can you check if all the DNS connectivity and AD related ports are open from the client to the DC? config-firewall-for-ad-domains-and-trusts

Also if you can check and configure the IP address of the DC in the DNS Section - network settings > change adapter options > select the current network adapter > right click it > IPV4 > check if the DNS server IP points to your DC. If not, please change it to your DNS server ip, then please open the CMD with administrator >> ping xxx.xxx.xxx.xx ( your DNS server IP) to see if the communication is working.
