Specified forest root domain: %1

The trust was created successfully, but it cannot be used for authentication for some or all accounts, because of name suffix conflicts. Some of the specified name suffixes already exist in this forest (or a forest that is trusted by this forest), so accounts with these names suffixes will not be routed to the specified forest.

Would you like to save a log file with complete details about the names associated with this trust?
