My development computer is running XP sql2005 while the production copy sits on a server 2003R2 sql2000 computer.
In the course of trying to get this function to work (switching from mssql to odbc) I have discovered that the ODBC driver versions are different between the two OS and that while the newer version (release date 17/2/07) that is able to be installed on 2003 handles this function fine, the older version doesn't.
Microsoft sites suggest that Vista might also handle it (ie have the newer driver). It also says that there are no plans to release the newer driver in a installable package.

Will hopefully test with the sql2005 on server 2003R2 in the near future to confirm it is the driver helping here.
