I have one query right now my NAV 2013 my RTC version is working but my development environment is not working it showing me error while connecting to database, any idea how to resolve this error.
The Following ODBC error Occurred:
Error:[Microsoft][ODBC Driver Manager] Data source name not found
and no default driver specified
I don’t know if you managed to fix this, but I’ve tried the registry route suggested in the article as linked to by Erik, but it creates loads of not-funcrioning driver entries you do not want. It did lead me to comparing this 64-bit machine to another which worked. I then discovered the NAV Development Environment requires the SQL Native Client 10.0 ODBC driver. Somehow it either did not get installed, or was removed from the system.
Installing this from the prerequisites folder on the Dynamics NAV installation media should fix the problem.
