SOLVED When join AD, I got "Unable to find domain controllers"

[fisherwei]

My FreeNas is: FreeNAS-9.3-STABLE-201501212031

This promlem looks like https://bugs.pcbsd.org/issues/6980
But, it should be fixed in 201412300101(http://download.freenas.org/9.3/STABLE/201412300101/ChangeLog)

In the webpage, when I press "save" button, I got "Unable to find domain controllers for <my domain>".
And in the /var/log/debug.log:

Code:

Jan 29 20:54:46 nas manage.py: [common.freenasldap:1053] FreeNAS_ActiveDirectory_Base.get_SRV_records: looking up SRV records for _ldap._tcp.dc._msdcs.<my domain>
Jan 29 20:54:46 nas manage.py: [common.freenasldap:1060] FreeNAS_ActiveDirectory_Base.get_SRV_records: no SRV records for _ldap._tcp.dc._msdcs.<my domain> found, fail!

FYI:

Code:

[root@nas] /var/log# host -t srv _ldap._tcp.dc._msdcs.<my domain>
_ldap._tcp.dc._msdcs.<my domain> has SRV record 0 100 389 mydc.<my domain>

Code:

Resolved.

I try to use python console to test dns.resolver function. It worked, but freenas still cannot join domain.
Then, I restart django and nginx, it back to normal.

:)

how exactly do you solve this problem?

how exactly do you solve this problem?

I just rebooted nginx and django services by ssh.

I think, full-reboot freenas can resolve also. Because my DC was installed after freenas, so maybe there are some DNS issue.
