Something that I've seen on several pages (especially some boards) is that an asp page generates a html page.
How this works is quite easy. When a page changes the asp page generates a HTML document. And uses a FileSystemObject to write the HTML file.
With the writing itself you can get help from here:
http://www.w3schools.com/asp/asp_ref_filesystem.aspSo what you do is when you change data from the database you let ASP generate the HTML file again.
This is not easy and will cost a lot of your time, but when it's done you have a unique reusable system.
But that's something you should do it you believe that Google doesn't find dynamic ASP pages, it doesn't actually have something to do with the language.
What is important tough is that the links to those pages are on other pages of the sites.
Here's a great topic about ASP and SEO (Search Engine Optimization):
