ASP Timeout

Hi, I have a website running on an NT server. The website is for a property firm and we constantly update the property details via a small ASP 'backend' and an MS Access database. In the backend, we use forms. We are currently having difficulties entering a large amount of data via these forms, as the server appears to 'timeout' before we have finished entering the details in the form and then when we press 'submit', we are told that the 'page cannot be found' and we lose the data. Does anyone know why this is happening, and how we can fix it? All comments/help would be greatly appreciated. ## Deliverables Help! ## Platform Windows NT server.
