Yes, that would work I think. In that case the steps to follow are

1. Install Perl, DBI, and DBD::ODBC on your Windows box.
2. Configure DBI::ProxyServer to meet your security needs.
3. Get dbiproxy running on the Windows box, preferably as a service (but make sure this service has permissions to get at your Access file!)
4. Use DBD::Proxy to connect to your Windows server from the Unix box.

Comment on Re^3: Help with installation and use of the DBD::ODBC module
