Ping

[cj]

I tried "www.microsoft.com and it came back False. Google is True. Are
sites able to specify not to reply to ping commands? Could that be why
Microsoft retursn False?

I need to find a site to ping to make sure my internet connection is
working. What site would you suggest I use?

Try
MessageBox.Show(My.Computer.Network.Ping("www.google.com", 1000))
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try

Yes, hosts may choose not to respond to ICMP ECHO (ping) requests, and
Microsoft's servers do not respond to them. I don't see any harm in using
Google.com, their servers respond to ping requests.

Hi Cj,

For network availability detection, you can also use the following static
method provided in .NET 2.0 network component:

#NetworkInterface.GetIsNetworkAvailable Method
http://msdn2.microsoft.com/en-us/library/system.net.networkinformation.netwo
rkinterface.getisnetworkavailable.aspx

hope also helps.

Sincerely,
