Hi,
I tried to export data from AX 2012 R3 environment using Microsoft dynamics AX test data transfer tool (beta). 
I used the cmd --  DP.exe H:/ExportDP <Databasename> <servername>
Also tried with providing domain name with the server name.
But I get the error --  cannot access databases <databasename>. No database found.
The SQL is in the same server only. And the SQL version is 2016 SP2. 
But the same cmd work for me in different environments in SQL2014 version. 
Kindly help me to find a solution for this issue.
