  Hi, 

  Can anyone help me with this error please?

  Microsoft SQL Service Login-Connection Failed
  SQL State: 'S1000"-SQL Server Error: 126
  [Microsoft] [ODBC SQL Server Driver] Unable to load communication module.Driver has not been correctly installed.
  Connection Failed-SQL State: '08001'-SQL Server Error: 0
  [Microsoft] [ODBC SQL Server Driver] Client unable to establish connection.

  This is a windows 2016 hyper V server with RDS installed and I am getting this error when trying to connect to a SQL backend on a different server. All other clients can connect to the server with the exact same login credentials provided in an ini file. I have tried installing ODBC drivers and I have set up a "System DSN" in the ODBC data sources of administrative tools but that hasn't helped. When testing the ODBC system DSN connection it connects successfully but the software won't connect and the software is using the same connection details.

  I have no idea where to go next. Can anyone point me in the right direction please?

  Thank you
  Paul.
