Cannot join server to domain

-

having trouble joining server 2012 r2 machine our domain. when try join domain (dc dc2, ip 172.20.1.11), following message:

an active directory domain controller domain domain.lan not contacted. 

details:

note: information intended network administrator.  if not network's administrator, notify administrator received information, has been recorded in file c:\windows\debug\dcdiag.txt.

following error occurred when dns queried service location (srv) resource record used locate active directory domain controller (ad dc) domain "domain.lan":

error was: "dns name not exist."
(error code 0x0000232b rcode_name_error)

query srv record _ldap._tcp.dc._msdcs.domain.lan

common causes of error include following:

- dns srv records required locate ad dc domain not registered in dns. these records registered dns server automatically when ad dc added domain. updated ad dc @ set intervals. computer configured use dns servers following ip addresses:

172.20.1.11

- 1 or more of following zones not include delegation child zone:

domain.lan
lan
. (the root zone)

______________________________________

the server has dns set correct ip (172.20.1.11) , can ping ip, cannot resolve fqdn.

when run nslookup returns default server dc2.domain.lan , ip of 172.20.1.11

i run set q=srv , _ldap._tcp.dc_msdcs.domain.lan , dc2.domain.lan can't find _ldap._tcp.dc_msdcs.domain.lan non-existent domain 

i have ipv6 turned off on both servers (dc , 1 trying join).

i have no clue else after spending morning trying different things. help?


   ipv4 address. . . . . . . . . . . : 172.20.1.11(preferred)
   subnet mask . . . . . . . . . . . : 255.255.255.0
   default gateway . . . . . . . . . : 172.20.1.30
   dns servers . . . . . . . . . . . : 127.0.0.1
 

dc should have own address 172.20.1.11 primary , 127.0.0.1 secondary (assumes single dc) ipconfig /flushdns, ipconfig /registerdns on both restart netlogon service or server.
