We're doing a migration with External 2-way trust configured between 2 domains (MS.local and Target.local). Moving all the resources from TARGET to MS.

Recently we got an error which says the followings:

Source:  DC1.MS.local This computer was not able to set up a secure session with a domain controller in domain TARGET.local due to the following:%%1311

This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.


I was wondering what we need to check to confirm sometihing is wrong!

Regards,
Anup

Go to Active Directory Domains and Trust in both domains and check if it is still there applied :)
To domain migration I would suggest ADMT from Microsoft

ADMT v3.0 is the tool which we're using to do this migration. Both the domains have the trust configured and listed in incoming/outgoing trust list.

I was trying to validate the trust from source and was getting the following error:

The secure channel (SC) reset on domain controller \\PDCEmulator.MS.ead of domain MS.local to domain TARGET.local failed with error: The security database on the server does not have a computer account for this workstation trust relationship.

Could you check DNS suffix configuration on those clients, please? How it is set up?

Try accessing PC by FQDN

server_name@target.local from MS.local machine
