I uploaded a new version of our SQL database to our co-located web server. During early development, which was done on an in-house box, I was able to change the connection string of the website and toggle between two different databases. One was new and one old.
I just tried doing this on our external site and am getting the following error when attempting to change back to the old database:
Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /Admin/Store/Security/Connection.aspx
I've checked the site and that file is certainly there. Shall I begin a reinstall or is there hope for my recovery?

This brings up a big question for everyone running live sites and development sites. How are you synchronizing your db changes to your live site?
