Hello All, We have configured active directory on one machine. Configured DNS server on ip 10.34.23.166 with domain test-success.com Tried adding one more machine 10.24.10.178 to the above created domain. it was throwing the below error: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt. The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller for domain apps-access.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.apps-access.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: 10.34.23.166 - One or more of the following zones do not include delegation to its child zone: apps-access.com com . (the root zone) For information about correcting this problem, click Help However we can able to access the two machines using UNC paths and via ping. Can someone check this and help us with any suggestions. Thank you in advance. Regards, Esther Francis.
