I have got computers that cant join domain using fqdn name, but by using the netbios name it works properly. I am also not able to promote a new child domain for the same issue. The dns query gives the correct result, corret domain controller but they are not reachable.I have made many test using dcdiag, netdiag, netdom, nlstest and all work fine. I have verified the TCP netbios service that is running. Below are the error reported when I am trying to join domain using the FQDN:
Active Directory domain controller for the domain it. kfc cannot be reached
DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain it.uci:
The query was for the SRV record for _ldap._tcp.dc._msdcs.it.kfc
The following domain controllers were identified by the query:
dc01.it.kfc
dc02.it.kfc
Common causes of this error include:
- Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses.
- Domain controllers registered in DNS are not connected to the network or are not running.
