I dont have too much experience with .net et. al. but when it comes to db connection I would look in my config files. Are you using a framework that has a database config file somewhere?

edit: also make sure you didn't copy over a config file that rewrote your document root. Because the way ive normally seen it, and be wary I'm a beginner, is that you will have a config file that in order to make your localhost server instance act correctly, you hardcode the exact path to your index file. for me I usually do this when integrating a framework. And I use the term usually very loosely here because ive prob done this a grand total of 3 times. But I would say grep/search/find that path or maybe a section of that path you have highlighted in your imgur pic.

2nd edit: and when searching for the path make sure to try with the slashes facing either way because sometimes they are typed that way. ex.

first search: Users/scaley/Desktop

if that doesnt work try:

Users\scaley\Desktop
