Sounds like it’s looking for your database files somewhere other than where they actually reside or the installation didn’t complete locally.
1. Double check that the file paths are correct.
2. Did you deploy an msi file from the server to be published to computers/users and then go to the workstation and install through add/remove programs? Where are the install files coming from a CD or a server? These areas could be issues.
3. What version of Office 2003 did you install? I believe that Small Business (and some other versions) doesn?t come with Access. So if a 2000 version with Access was uninstalled before the 2003 installation, you would be missing Access files all together.
Don’t know if this helps. Just my two cents.
