Failing parent-child trust relationships

[Guest]

Im having troubles with a parent-child trust relationship. I have I root
domain and 3 child domains, relationships with 2 child domains are working
just fine, but with a domain is failing. After verifying the connection in AD
Domains and Trusts it shows me an error of secure channel with the remote (
child PDC emulator DC) server, then AD tries to reset the secure channel but
it does not works.

I change roles of child domain to another server but error keeps happening.
And it does not allow me to recreate it.

Any help would be greatly appreciated

Oswaldo,

Can you tell us how you have your DNS configured and how you have your
domain and forest FSMO roles placed. From there we should be able to help.

dc01 in parent ( root domain ) supports schema, domain naming, rid, pdc and
infra masters. dc02 in child domain supported the 3 roles for the child
domain, but i already changed it to another dc in child domain

DNS zone in root domain is AD integrated and is on the same server ( which
also has a secondary zone for the child domain ). DNS zone for child domain
is hold in DC02 as AD integrated and supports also a secondary zone for the
root dns zone.

kind regards
