Okay...This uses 'Ping-Host' from PSCX PSSnapin. My function still doesn't do what I want it to do but..more promising. Give function first three octets (and hard code range - 1..254) , Bytes, Wait, Count (which only works as below with count of one right now...) Then Prints (only) Hosts UP, IP Address, AverageTime, MinimumTime, MaximumTime, Loss as so....Stats are misleading since I think (?) it is the ave, min, max for each separate run? )....Will fix this...and TTL...Man, Powergui is helpful. So are the NetCmdlets. Anyway, 'ping-host' is faster..than accessing the .NET ping(send) functionality from the post before this. My programming logic is still not standard. I should be using params and arrays as Holmes and Payette specify
