not to knock isa server(i haven't had much of a chance to look it over), but
for the record, there have been a few DOS attacks, and one heap corruption
attack with the possibility to execute code.
search sf for the dos, and here is a link to dark spyrit's explanation of
the attack against the heap corruption vuln/
http://www.securityfocus.com/cgi-bin/archive.pl?id=1&mid=179986

basically, just because nobody has a script doesn't mean that nobody can
make an isa server do bad things:)
