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.
