Turns out that it was a much simpler issue than I thought. For whatever reason, the development server was not using Port 1433 as the default port in the connection and was instead using Port 4000.

I discovered this by enabling the logs in the freetds.conf file and monitoring them as I was making the request.

Also, something to note: The DBLIB extension uses a colon (:) as a separator between the host and the port instead of the comma. Unfortunately, the error that you receive when you use a comma isn't very descriptive, so hopefully someone benefits from this discovery.
