>What approaches would work well for allowing individuals to access and update personal info on themselves from any web browser?

>We have a database of free tables on our main file server on our LAN. Among other things, we maintain a database of info that clients voluntarily submit to us for distribution to organizations that might be interested in that info. The information may change over time, so we want the clients to be able to access and update their info at any time using a userid and password.

>Our main web site for this service is being hosted at an ISP. We would like for the client to go to this web site and click a link that takes them to the user access screen. At this point we would like to set up a secure link to our database and allow them to enter the user ID and password, after which their record will appear to them. They should then be able to edit the record, along with several related child records, and commit the changes to the database.

>Our attempts so far have not met with much success. I have set up an IIS server with ODBC drivers from VFP6 SP3. It seems that we cannot access the database with .asp scripts on the hosted web server, and our plan at the moment is to redirect the client to the IP address of the IIS server on our network. I am also having difficulty getting the .asp script to find the .dbf file through ODBC. In addition, I'm not crazy about having an anonymous access port directly to our database.
