Checking Internet connection on Vista

[Eric Chatonet]

Bonjour à tous,

On Win, I am used to run the following handler to know if the user is  
connected to the Internet:

function InternetConnected
   local tAddress
   -----
   put hostNameToAddress(<domain name>) into tAddress
   return tAddress <> empty
end InternetConnected

When the user is not connected and using XP, this function return  
false immediately. So far so good.
But with Vista, it's another story: it works well if the user is  
connected but Rev hangs during a long time before returning false if  
he is not.

Any hints to check reliably and quickly Internet connection with  
Vista would be much appreciated.

Best regards from Paris,
Eric Chatonet.
