Jochen... dude, you need to fire up a Windows 95 client and try a ping to a valid address that is not responding.

You will see: Request timed out

in the result on the console. I said nothing about NT/2000/XP this test is ONLY for Windows 95

I might assume that 98 responds the same, not sure about ME as it did add some minor new stuff that 2000 has.
