SYMPTOMS
When you are trying to attach a SQL Server table or trying to use a table that has already been attached, you may receive the following error message:

Data source not found and no default driver specified.



CAUSE
You may have a missing, damaged, or incorrect ODBC.INI file.

Other situations may indirectly cause this error message. For more information, please see the following article here in the Microsoft Knowledge Base:

RESOLUTION
Verify the following:


 * There is an ODBC.INI file in your WINDOWS subdirectory.
 * There is only one copy of the ODBC.INI file available on the computer you are using.
 * The entries in the ODBC.INI file are correct for the SQL database server to which you want to connect.



MORE INFORMATION
The contents of your ODBC.INI file should resemble the following:

  [ODBC Data Sources] MYSERVER=SQL Server YOURSRVR=SQL Server

[MYSERVER] Driver=C:\WINDOWS\SYSTEM\SQLSRVR.DLL Description=SQL Server on server MYSERVER OemToAnsi=No Network=dbnmp3 Address=\\MYSERVER\PIPE\SQL\QUERY

[YOURSRVR] Driver=C:\WINDOWS\SYSTEM\SQLSRVR.DLL Description=SQL Server on server YOURSRVR OemToAnsi=No Network=dbnmp3 Address=\\YOURSRVR\PIPE\SQL\QUERY

You will receive the error message if there is no section that refers to the SQL database server to which you are trying to attach or if any one of the following is true:


 * The [MYSERVER] section is missing.
 * The Driver= line is missing.
 * The .DLL file on the Driver= line is missing its .DLL extension.
