David,

You need to show the ODBC definition. The first error is the important one:
Connection string is not valid.

One thing that often raises this problem is that the SQL Server instance
name is not fully specified. For example, your server machine might be
SBSServer, but the SQL Server instance could have been installed as
SBSServer\MyCompany. So, if the full instance name 'SBSServer\MyCompany'
was not specified in ODBC, the connection could not find the SQL Server with
only SBSServer.

Of course, it could also be something else. More information is needed.
First, however, you might want to read:

Be sure to read the Q/A discussion as well.
