This might be a question along the lines of "is it plugged in?", but do
you have the Office 2007 version of the ODBC drivers installed?

If not, then your results would not be a surprise.

If you do, then we should get Prof. Ripley involved here, as we did have
a brief offlist communication on this yesterday, thinking that RODBC
"should" work if the proper version of the ODBC drivers are installed.

Let us know.
