How to do nslookup for SRV

[Nathen]

Hi. I have installed the Active Directory directory service and need to verify Service Location locator resource records for a domain controller. Someone has suggested me to do it by Nslookup. I dont have the perfect idea of doing that. Could you guys please make me know how can i do nslookup for SRV ?

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.

Thats it !!!

Once you have done nslookup for verifying the SRV records, it will show one or more SRV service location records that appear in the following format, where Server_Name is the host name of a domain controller, and where Domain_Name is the domain the domain controller belongs to, and Server_IP_Address is the domain controller's Internet Protocol (IP) address:

Server: localhost
Address: 127.0.0.1
_ldap._tcp.dc._msdcs.Domain_Name
SRV service location:
priority = 0
weight = 100
port = 389
srv hostname = Server_Name.Domain_NameServer_Name.Domain_Name internet address = Server_IP_Address

After you install Active Directory on a server running the Microsoft DNS service, you can use the DNS Management Console 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, 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:
_kerberos
_ldap
