Windows Server 2003 includes a 64-bit version of the Microsoft ODBC Data Source Administrator, which is the default Administrator application located in the Windows Control Panel under Administrative Tools. Its icon is named Data Sources (ODBC).
The 64-bit ODBC Administrator is named odbcad32.exe, and is located in the %systemroot%\system32 folder in a different directory than the 32-bit.
The 64-bit icon and the associated 64-bit ODBC Administrator
should not be used for creating or configuring ECDA Data Sources.
