Peter,
In addition to what Nigel posted, you could probably use Rick Strahl's wwIPStuff utilities. HTTPPing gives you the ability to ask if a certain URL exists (similar to the way Ping can ask if a certain IP address exists). Because it uses the HTTP protocol over port 80, it usually isn't blocked by firewalls. If you get a response you can enable all the links. If not, disable what you need.

HTH.
