For those of you who plan to download WIN XP SP2, they evidently have not included support (TCP sends) for RAW SOCKETS (SOCK_RAW). While this move by Microsoft, I believe is not bad, I have heard of some users having trouble with firewalls (other than Microsoft's own WINDOWS FIREWALL). For more info on raw sockets, see links below : http://grc.com/dos/sockettome.htm http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/tcp_ip_raw_sockets_2.asp http://www.theregister.co.uk/2001/06/12/security_geek_developing_winxp_raw/ http://www.informit.com/articles/article.asp?p=27289&redir=1 Over at BBR, there is a good thread on-going about WIN XP SP2 and what is coming, including what problems to anticipate and possible how to solve them: http://www.broadbandreports.com/forum/remark,10981741~mode=flat

thanks for the info
