How to Learn the IP Address of Your Active Directory Server

Recently I needed to learn the IP address of our active directory server(s). I wanna share how I learnt it/them.

First open your command shell. (cmd.exe) Then type the following: (I masked our IP addresses below of course where you will see some X's, Y's or Z's or some combination of letters.)

C:\Windows\system32> nslookup

Default Server: xyzt.abc.local

Address:  10.xxx.yyy.zzz

> {This prompt is where you will/can do some DNS queries}

> set type=all

> _ldap._tcp.dc._msdcs.abc.local {abc.local is the name of our domain}

The output will be the following:

Server:  xyzt.abc.local

Address:  10.xxx.yyy.zzz

_ldap._tcp.dc._msdcs.abc.local      SRV service location:

          priority       = 0

          weight         = 100

          port           = 389

          svr hostname   = server1.abc.local

_ldap._tcp.dc._msdcs.abc.local      SRV service location:

          priority       = 0

          weight         = 100

          port           = 389

          svr hostname   = server2.abc.local

_ldap._tcp.dc._msdcs.abc.local      SRV service location:

          priority       = 0

          weight         = 100

          port           = 389

          svr hostname   = server3.abc.local

_ldap._tcp.dc._msdcs.abc.local      SRV service location:

          priority       = 0

          weight         = 100

          port           = 389

          svr hostname   = server4.abc.local

{Below are the names and IP addresses of our active directory servers}

server1.abc.local   internet address = 10.xxx.yyy.zzx

server2.abc.local   internet address = 10.xxx.yyy.zzy

server3.abc.local   internet address = 10.xxx.yyy.zzz

server4.abc.local   internet address = 10.xxx.yyy.zzt

Four server are listed after executing the command because it seems that we have four active directory servers in our company. This also a new information for me =) )
