Discover process in RUM fails with long computer names fails with "Error 0x800706ba. The RPC server is unavailable"
Using an import file to populate RUM with long computer names (15 Characters or longer) with similar naming causes failures in RUM. The Names are truncated, and therefore RUM cannot determine which computer is which based on the computer names.
MYWORKSTATION2445$ is detected as MYWORKSTATION24
Therefore the workstations fail to be discovered.
Migration Manager requires DNS connectivity in all aspects with the exception of a workstation move.
Please see this article for further information on this requirement:
Rename the workstations to fit the 15 character or less requirement.
This will be resolved in later versions of Migration Manager for AD / RUM
