Symptoms
When creating a new SQL Server Data Source Name (DSN) using the ODBC API SQLConfigDataSource function, a network library must be specified. If the network library name is in lowercase letters, the Client Configuration dialog box may show it as “Other”.
Resolution
In Control Panel, the Client Configuration dialog box in ODBC Data Source Administrator is case-sensitive. It compares the network library name from the registry to uppercase network library names. See the “More Information” section for information on the registry entries that are affected by SQLConfigDataSource.
