Hi

If you run your script on a Windows XP or Windows 2003 Server, you
can use the WMI class Win32_PingStatus to ping a computer.

http://msdn.microsoft.com/library/en-us/wmisdk/wmi/win32_pingstatus.asp

For Windows 2000, parsing the output of ping.exe is your best option.

Take a look at the VBScript function IsConnectible in the link below,
it redirects the output of ping.exe to a file and then and looks for
the text "TTL=" to see if the remote computer is online.
