[Zope] Problems with ZODBC and Ms SQL Server 7.0

Anyone ever figured out how to get ZOPE's ODBC DA to work with MS SQL Server? I am using MS SQL Server 7.0, Zope version 2.1.6, Python 1.5.2 Win 386 and ZODBC Version 3.1.0b2. Whenever I attempt to open an ODBC connection to the SQL Server I get the message "Invalid connection string:" followed by the name of the DSN I am trying to use. Can anyone help me along with this or is this the curse for using Microsoft software? Yours sincerely, Robert Honore.
