Host _ldap._tcp.domain.com not found: 3(NXDOMAIN)

Hi, all

From 3 days I'm stuck with AD service on FreeNAS. I tried everything but can't and can't join it in AD. The version of FreeNAS is 11.1-STABLE. At the end of the day i cannot understand why it can't resolve the SRV records for _ldap. The strange thing is that it does it 1 of 10 times. It is not a AD or DNS issue, my other clients/servers resolve them with no problem. Yesterday I installed a test FreeNAS which is FreeNAS-9.3-STABLE. There i could not join the AD either, but this time the error from the terminal is:

Code:

Traceback (most recent call last):

	"Unable to find domain controllers for %s" % self.domainname)
freenasUI.common.freenasldap.FreeNAS_ActiveDirectory_Exception: Unable to find domain controllers for None 

From the GUI the error for both is the same "Unable to contact domain controllers for "domain.com".
