I have a parent child domain. Connections between the parent and child are all open. All ports are check and communication is connectable.
I know there is a replication issue. And now there is a trust issue. I tried to reset trust passwords.I tried to validate the trust but after entering credentials for both domains I get a "The Parameter is incorrect" And "Trust Cannot be repaired because: The Parameter is incorrect"
This message comes up also.
"The secure channel (SC) reset on domain controller \\dc1.domain.com of domain domain.com to domain dc2.Child.domain.com failed with error: There are currently no logon servers available to service the logon request.
The secure channel (SC) verification on domain controller \\dc2.Child.domain.com of domain dc2.Child.domain.com to domain domain.com failed with error: The specified network password is not correct.
