When creating a move task and clicking select to pick a domain the following error is displayed:
"The list of servers for this workgroup is not currently available."
This can happen if the Computer Broswer service is not running on the computer that the Resource Update Manager (RUM) is running on or if more widespread computer browser issues are occuring
To resolve the computer browser service should be started if stopped.
To workaround the downlevel domain name can be typed in and then the browse button can be clicked. If that is able to find the domain and list OUs then you should be able to progress
