(Debug   :02732) 10/1/2004 17:44:03 Radius ODBC Connection Error: DataSource VoIPRadius

Cause(s) : This is an ODBC error returned either from the ODBC Driver or Microsoft SQL. VOP Radius is reporting rather than generating the error. A list of possible causes includes the following:

* MS SQL Server down
* The wrong MS SQL Server specified under the ODBC Driver
* The credentials to connect to the database are wrong in either VOP Radius or the ODBC Driver.
