in reply to Ping2

Why not just use hping from http://www.hping.org/ - it can ping to a specified port using specified TCP-Flags.
hping -S -p 80 www.perlmonks.org HPING www.perlmonks.org (eth0 209.197.123.153): S set, 40 headers + 0 +data bytes len=46 ip=209.197.123.153 flags=SA seq=0 ttl=49 id=34387 win=65535 rtt +=113.7 ms

    Does hping work on Windows? (The OP mentioned being in a shop that does nearly exclusively that.)
        Ah, cool, even a native one. ++.

        (I was actually looking for something like that for a while, but that was a while ago)
