Active Directory DNS response does not contain answer to question

[kyle_macaulay]

Hello everyone,

@anodos you appear to be the SME on active directory so figured I'd request your assistance if you have the time.

I've had my truenas system successfully joined to my domain for quite some time. Out of nowhere, I'm having an issue I can't seem to wrap my head around. I logged in and noticed I was no longer connected to my domain so I attempted to reconnect the domain and I constantly get answers along the lines of below:

Code:

Error: Traceback (most recent call last):

dns.resolver.NoAnswer: The DNS response does not contain an answer to the question: _gc._tcp.MACAULAY.COM. IN SRV

Below is what I have gathered in my request for assistance on this issue please let me know what else i may need.

Code:

root@Truenas[~]# host -t srv _ldap._tcp.macaulay.com
_ldap._tcp.macaulay.com has SRV record 0 100 389 domaincont.macaulay.com.

Code:

root@Truenas[~]# net ads lookup -S macaulay.com
