All, That little page I sent seems to kill some systems and not others. Mainly, SP2 seems to stop this problem from happening. Is there anyone running 2k SP2 that dies with the shell://:? I'd really like to find out what causes this, and what the difference is between SP1 & 2 (if it _is_ SP2 that fixes it). Bearing in mind that the gopher one DOES crash SP2, theres obviously something different, and some significance of "shell://". Also, as someone else posted, anyone else have any ideas if this exploitable any further?
