Re: Dns.GetHostEntry functionality

I'm no Vista expert. Try resolving www.microsoft.com. I'm pretty sure that
will work.

If I substitute 10.0.0.20 for david-1, everything works fine. That is, the
functionality of my app works to connect to the PC and retrieve data and
send data. So this tells me that I have connectivity to the network. It is
just that DNS seems not work work. Does Vista not use netbios names? I am
pretty sure that it does.

The only thing that I can think of is that the name you're asking for is
wrong (isn't the real device name), or that there's a bug in resolution
for NetBIOS names with - characters in them. What sort of device are we
talking about (it's not Windows Mobile, for example?)? Version of CE?
Networking components built in?

Your code works fine on my device.

I have this code:

try
{
IPAddress[] addresses =
Dns.GetHostEntry("david-1").AddressList;
foreach (IPAddress address in addresses)
{
if (address.AddressFamily ==
AddressFamily.InterNetwork)
{
m_strServeIP = address.ToString();
break;
}
}
}
catch (SocketException ex)
{
MessageBox.Show(ex.Message);
Close();
return;
}

A SocketException is thrown "No such host is known".

Yet, I know I have connectivity since I can browse the internet and I
have a valid ip address and it can be pinged from the david-1 computer.
My DHCP server is giving out dns and gateway information. Why does the
GetHostEntry fail?
