    Windows 7, BSOD from SMB network lookups

    Watch out if you start using Windows 7, it can be remotely crashed by anything
    that can connect to the 443 port (SMB). Make sure your router doesn't let traffic through on 443 before installing 7, or wait for a patch. 443 is for local
    file network access, so should never go through your routes or gateways.

    How do you know it's Windows 7 causing the BSOD and not a network adapter driver which wasn't properly tested by the manufacturer? It's fairly easy to blame Windows for your problems (most people did with Vista) but when 90% of all the problems resulted from hardware manufacturers lack of ability to keep their devices up-to-date and stable I find it hard to believe that your problem is the result of Windows alone (especially as BSOD's are almost exclusively hardware related).

    Well, its not windows 7 per se, but there is a nasty flaw in SMB 2.0 that effects windows 6 or higher (that would be Vista or later).

    Before there is a panic, should be noted the final version of Windows 7 and Windows Server 2008 R2 is not effected by this bug. Nor is this bug really exploitable from the net, unless under certain conditions: first for a remote attacker to exploit this hole they must get past the first. Most consumer router+firewalls black port 445 which is used by Microsoft DS (SMB connections). The other way is to have the user download a malicious file. There is a third way where a rouge device is placed on your private network, but then this bug is the least of your concerns then.
    Logic without the fatal effects.
