Steve,
The ping command (from command prompt) uses a protocol called ICMP; Microsoft's website and others (apparently weather.com) blocks ping requests using ICMP to reduce traffic. internetCheckConnection() call works properly on microsoft.com and weather.com.
I don't know if your firewall could interfere, but I doubt it.
Are you using the full URL? "
http://www.weather.com"

>Thanks for the reply. I tried your suggestion, and I get false re. checkinternetconnection even though I can access internet via IE over our LAN... see code below... Could it be a firewall issue? I cannot ping microsoft.com or weather.com from DOS prompt but I can ping a DMZ server using the full server name. What am I missing?
