and the Data Transfer Tool stopped with below screenshot.

Solution:

Add Server name (instance name also if you have) to DP command like


[DP.exe IMPORT D:\DynamicsAXR3DemoData MicrosoftDynamicsAx GGK-DYN-001\MSDYAX]


Where GGK-DYN-001 is Server name and MSDYAX is Instance name

 And it starts importing
