Well, that is weird, first thought was faulty replication, but it has
replicated to the old DC and isn't showing on the new DC.
I have checked on my DC's and the rid FSMO transferred OK. I would
check if the FSMO roles are still showing as being on two DC's (if you
have more than two DC's, check those as well). If they are, try
transferring them back and see what happens. If they do transfer back,
you need to examine gtmad2 to see if there is anything wrong with that.
