second DC on Technical Preview 2


i installed technical preview 2 on 2 lenovo ts-440 server computers

on first computer have ad/ds (active directory / domain services) , running;

i installed ad/ds role on second computer,
having difficulty completing promoting second server domain controller
by: "add domain controller existing domain"
gives error: "an active directory domain controller domain ... not contacted"

from second server computer able ping domain on first computer,

and, third computer, able login first ad/ds computer
via remote desktop via ad/ds login;
seems indicate ad/ds indeed functional on first server computer

however: > dcdiag /test:dns /n:domain_name /s:first_servername /v
returns error: ldap search capablity attribute search failed on server ..., return value = 81

i've joined ad/ds on server 2012 r2,

might know if such ability might have been changed on technical preview 2? 

hi

 yes,on first domain controller , second server(which try add addtional domain controller;

- control panel->network , sharing center ->see domain network (your domain name) connections click ethernet ->click properties->uncheck internet protocol version 6(tcp/ipv6).

also check firewall disabled each server,and make sure second(try to add) server dns adress set first domain controller.

make sure dns service started on first dc.
