How to Verify the Creation of SRV Records for a Domain Controller

Summary

This article describes how to verify SRV locator resource records for a domain controller after you install Active Directory.

More Information

To verify SRV locator resource records for a domain controller, use the appropriate method.

Using DNS Manager

After you install Active Directory on a server running the Microsoft DNS service, you can use the DNS Manager Microsoft Management Console (MMC) snap-in to verify that the appropriate zones and resource records are created for each DNS zone. Active Directory creates its SRV records in the following folders:

_msdcs/dc/_sites/default-first-site-name/_tcp
_msdcs/dc/_tcp
In these locations, an SRV record is displayed for the following services:
_kerberos
_ldap

Using the Netlogon Service

If you use non-Microsoft DNS servers to support Active Directory, you can verify SRV locator resource records by viewing the Netlogon.dns file located in the %SystemRoot%\System32\Config folder. You can view this Netlogon service document using a text editor. The first record that is displayed is the domain controller's Lightweight Directory Access Protocol (LDAP) SRV record in the following format

_ldap._tcp.domainname
where domainname is the name of your domain.

Using Nslookup

  1. From your DNS server, type nslookup at a command prompt.
  2. Type set type=all, and then press ENTER.
  3. Type _ldap._tcp.dc._msdcs.domainname (where domainname is the name of your domain), and then press ENTER.
Nslookup returns one or more SRV service location records in the following format

hostname.domainname internet address = ipaddress

where hostname is the host name of a domain controller, domainname is the domain to which the domain controller belongs, and ipaddress is the domain controller's Internet Protocol (IP) address.
