Keeping your ADO components up to date may seem like a trivial
thing, but it's really not. In addition to new features that can
make your coding easier, the latest drivers almost always
contain bug fixes and performance enhancements over the
previous version.
While you may not want to be on the "bleeding" edge and
update your MDAC stack the day the new versions come out, you
should try and stay somewhat current.
You can get the latest version from
Microsoft's Universal Data Access
webpage. If you're not sure what version you have, this little
ASP script can help you find out.
