How can I find the LDAP server in the DNS on Windows?

  • 772

For Linux, this command should return the DNS record for the LDAP server

host -t srv _ldap._tcp.DOMAINNAME

(found at Authenticating from Java (Linux) to Active Directory using LDAP WITHOUT servername)

How could I get the same on the Windows command line using nslookup?

I tried 

nslookup -type srv _ldap._tcp.DOMAINNAME

(following http://support.microsoft.com/kb/200525), would this be correct?

windows domain-name-system ldap nslookup

    You need to use an = after -type:

    nslookup -type=srv _ldap._tcp.DOMAINNAME

  2. In cmd shell:

    nslookup 
set types=all
_ldap._tcp
    • 15

  3. None of the above worked for me, I got every time an error like this (I've tried with all the combinations I can think of with the domain names):

    *** Unknown can't find _ldap._tcp: Non-existent domain

    So another google search pointed to this method:

    nltest /dclist:yourdomain.com

    And this results in the list of the different servers in my network. Hope this saves an additional 2 minutes for someone else.

  5. Get-ADDomainController will list your domain controllers from domain If you want to check it from another domain then use -server switch.

    get-addomaincontroller -server "domain"

  6. Windows cmd prompt uses "query" instead of "type" for some forsaken reason. Interactive nslookup still uses "set type=srv".

    nslookup -query=srv _ldap._tcp.DOMAINNAME

    EDIT: while "query" works it seems that I am 100% wrong. "type" works too.

  7. "nslookup -query=srv _ldap._tcp.DOMAINNAME" worked for me, tried nslookup -type=srv _ldap._tcp.DOMAINNAME and didn't work.
