I got the same error when I forgot to install the correct Microsoft SQL Server Native Client on the MQM system.
i have installed Microsoft SQL Server 2012 Native Client (packege for x64) before to test connection do SQL Server 2012....
I cannot remember which exact version I installed, but I remember I tried several different. Have you tried x86 and perhaps the SQL Server 2008 R2 NC?
Use the version of native client.
with software linked by you i have fixed the issue. Strange but true, to use MQM eith SQL 2012 I have had to use Natice Client x64 for SQL 2005
We saw some issues in support with the SQL 2012 Native Client which a hot fix is available HF1007572 if you contact support and open a SR they will be able to provide you a copy.
