SAS Recently updated the Third Party Software page for SAS equipment (http://support.sas.com/thirdpartysupport). In order for Xythos to successfully integrate with SAS, if SQL Server is used the database version it must be MS SQL Server 2000.
MS SQL Server 2005 is not supported for the integration between Xythos and any SAS v9.
The SP2&3 page still states: "MS SQL Server 2000 or higher," which is actually not correct. But no matter, if you are just now installing SP3 ... that is another blog post :)
