I also used BBR's DrTCP application to make sure that black hole router detection was, in fact, enabled on my XP box before commencing my packet captures. I cannot explain why it made no difference, but at the same time I don't know enough about how WinNT's black hole router detection works to begin speculating at this point. I do plan on looking into it, however. -- Nathan Anderson First Step Internet, LLC nathana@xxxxxxx _______________________________________________ NANOG mailing list NANOG@xxxxxxxxx http://mailman.nanog.org/mailman/listinfo/nanog
