How to check for internet connection via LAN

Is there an easy way to check if there is an internet connection via LAN?
I want to check whether I can connect to a certain URL using a LAN
connection, and if this is not the case, connect using a dial-up connection.
Which API calls can I use?

No. That is one of the harder types of connections to detect since an
external computer is managing the actual connection.

Then just conect to the URL and see if it fails.

Why don't you let the user decide what kind of connection to use?

InternetOpen
InternetOpenUrl
etc etc.

Just keep in mind that the first three functions in that list are not
reliable.
