ASP pages not working after move to new server

I moved my website to a new server. All files appeared to upload seamlessly. The home page and any .html page on the site will load just fine. However, any productcart asp page (eg. CustPref.asp,, viewcart.asp, contact.asp, checkout.asp etc) will not load. The store has basically been disabled. I get http 500, website cannot display the page. Any thoughts regarding why this is happening?

The asp page problem is now resolved. I pushed another copy of the ProductCart directory to the server from home (avoiding corporate routers/filters). I can now see asp pages through my browser. However, the new sql database is still not working. The new database has a different name from the original one. I restored the data from the origianl database to the new one and ensured that the connection string was set up correctly (diagnostics confirms that it was). However, I still have no access to the database from the site. it should be noted that when I restored the database, it reported that the database was restored successfully but also reported an "orphaned user" (it wa actually the name of the original dbo). It looks like the tables in my new database are still owned by the former sql user and not recognized by the new dbo?? Not sure how to change ownership of sql tables if that is indeed the problem. Anyone have a quick fix for that?

Yep, sounds like a problem with db ownership.
