When trying to add a default ACL to a chosen folder in the file migration objects in your Project Options of NDS Migrator, you select the add button and nothing happens. The "Add Trustee and Permissions to Default ACL" window does not appear and you are not able to apply any default ACL's.
The reason for this is due to the fact that the machine where NDS migrator is installed may be pointing to a DNS Server that is incorrect. If your network is running multiple DNS servers, please try to use an alternate DNS Server to see if this resolves your issue. The machine is unable to populate the User objects in the domain since it is not able to resolve it through DNS.
