Requested server name not found error.

I'm using Windows Server 2012 R2.

I have installed Sybase Ase 16.0 windows 64 bit SDK and configured Servers using DSEDIT. In datastore I can configure ase server and I can see data in it.

But after designing Dataflow and Executing job, I get error "Requested server name not found".

I can connect ase server using isql command line.

In ODBC 64bit I can connect ase server with 64 bit driver.

I checked environment variables.

I couldn't find any solution to solve this problem.

Please help me.

Thank you.
