Hello all, Hope this post finds you in good health and spirit. This post is about SRV DNS records.
The SRV record is a Domain Name System (DNS) resource record that is used to identify computers that host specific services. SRV resource records are used to locate domain controllers for Active Directory also SRV records are used in locating hosts that provide certain network services.
How to verify the SRV records
We can verify the SRV locator resource records for a domain controller, use one of the following methods.
Active Directory creates its SRV records in the following folders, where Domain_Name is the name of your domain:
Forward Lookup Zones/Domain_Name/_msdcs/dc/_sites/Default-First-Site-Name/_tcp Forward Lookup Zones/Domain_Name/_msdcs/dc/_tcp
In these locations, an SRV record should appear for the following services:
Nslookup is a command-line tool that displays information you can use to diagnose Domain Name System (DNS) infrastructure.
To use Nslookup to verify the SRV records, follow these steps:
- On your DNS, click Start, and then click Run.
- In the Open box, type cmd.
- Type nslookup, and then press ENTER.
- Type set type=all, and then press ENTER.
- Type_ldap._tcp.dc._msdcs.Domain_Name, where Domain_Name is the name of your domain, and then press ENTER.
If you are using non-Microsoft DNS servers to support Active Directory, you can verify SRV locator resource records by viewing Netlogon.dns. Netlogon.dns is located in the %systemroot%\System32\Config folder. You can use a text editor, such as Microsoft Notepad, to view this file.
The first record in the file is the domain controller’s Lightweight Directory Access Protocol (LDAP) SRV record. This record should appear similar to the following:_ldap._tcp.Domain_Name
So, that’s all in this blog. I will meet you soon with some other stuff. Have a nice day !!!
