You can use ping to tell if the computer is on the network.  It is not exactly vbcode, but it works.  Just do the following:

dim tempstring as string
dim computername as string   'has the name of the computer you
                             'to identify on the network

open "temp.bat" for output as #1
print #1, "ping " & computername & " > temp.tmp"
close #1
shell("command.com /c temp.bat", vbhidden)
open "temp.tmp" for input as #1
line input #1, tempstring
line input #1, tempstring
line input #1, tempstring
close #1

if instr(tempstring, "Request timed out.") then
   msgbox "computer not found",,"error"
else
   msgbox "computer found",,"found"
end if



this is rough code, you can parse the file different ways and clean up this code, but it should work.
