For the sake of someone who may google this, so far I've done the following:
- Began scanning files, and added "%windir%\system32\drivers\etc\hosts"
- Began rescanning the entire network
- While that was brewing, made a custom report to list any machines with that file not equaling the size of a hosts file with no entries (!= 824)
I used these two links to make the report:

If anyone has a more eloquent way of doing this, let me know
