Use the following information to troubleshoot the file.

"Error resolving domain" error

If the file already includes an entry for a domain, and you try to create a new directory of a different type for the same domain, an "Error resolving domain" occurs. You must edit the file and manually remove the domain entry before creating the new directory.

Domain controllers are unreachable

Once a domain entry is added to the file, it is not updated automatically. If any domain controllers listed in the file become unreachable, edit the file manually and remove them.
