What you have done should be fine however try adding a bit more detail to the ping.

VB

Dim options As New PingOptions()

			' Use the default Ttl value which is 128,
			' but change the fragmentation behavior.
			options.DontFragment = True

			' Create a buffer of 32 bytes of data to be transmitted.
			Dim data As String = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
			Dim buffer() As Byte = Encoding.ASCII.GetBytes (data)
			Dim timeout As Integer = 120
			Dim reply As PingReply = pingSender.Send (args(0), timeout, buffer, options)

this was taken from http://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping.aspx[^]

Also in the exception, try catching the PingException first as this may yield more detail about the exception.

Solution 1

The obvious questions are :-

1. What is the exception you get back, there are 5 documented[^]
2. Does 'xyzMicrosoft' resolve through DNS?

An additional observation, is that the timeout is in milliseconds, not seconds, so you're only waiting for 5ms (which should be fine for a machine on the same subnet)

PingException

barneyman 14-Jun-12 5:57am

You are catching a generic exception, that API hands 5 different exceptions back, handle them all - documentation on how in VB is here

Catch the PingException, get the message from that, examine the InnerException if there is one, and get it's message - all the clues are in the documentation, take time to RTFM
