Can we confirm what I think the above means:
You have a NT4-style PDC
You have 'DomainB' in which there is a Windows 2012 AD DC running as
domain functional level 2008 (This is NOT a PDC)
You are trying to set up a trust between the PDC and the AD DC

Again, you have an AD DC running windows 2008 and you can configure a
trust, but you don't say between what.

Sounds like it.

Should do, but microsoft seems to be trying to make it harder, see

They will not do anything on a PDC, they are meant for an AD DC
