Marcus dropped by the office to remind me about an email he sent asking
how to do bcast WinPopup messages. We looked at how WinXX did it with
tcpdump-smb and found it is a mailslot to UDP/138. I hacked up a file
with the appropriate data and tested it with netcat, managing to send
messages to Win9X and NTws with no problem. I found that the message
limit is about 512 bytes - quite a bit larger than the size that the
WinPopup GUI can do. If you send larger than that to NT then it rejects
the message. Win98 gets a fatal error in WinPopup. Some devious person
could probably turn that into a exploit if they wanted to.
