We have an existing two-way forest transitive trust and everything is working. I added two new domain controllers and when I try to validate the trust I get an error message:
The Local Security Authority is unable to obtain an RPC connection to the active directory domain controller abc.com. Please check that the name can be resolved and that the server is available.
I can ping the DC referenced in the error message.
I have checked the event logs and I am not seeing any errors.
I have run dcdiag on the new servers and everything looks ok.
Any ideas??
Thank you
