The hotfix for the 'NetBIOS Name Server Protocol Spoofing'
problem has not been applied.

This vulnerability allows a malicious user to make this
host think that its name has already been taken on the
network, thus preventing it to function properly as
a SMB server (or client).



Solution : See http://www.microsoft.com/technet/security/bulletin/ms00-047.asp
or Security Rollup: http://support.microsoft.com/support/kb/articles/q299/4/44.asp

Risk factor : Medium";


 desc["francais"] = "
Le hotfix pour le problème de spoof du protocole du
serveur de noms NetBIOS n'a pas été appliqué.

Cette vulnérabilité permet à un pirate de faire croire
à ce serveur que son nom NetBIOS a déjà été pris
par une autre machine sur le réseau, ce qui l'empeche
de s'établir en tant que serveur ou client SMB.

Solution : cf http://www.microsoft.com/technet/security/bulletin/ms00-047.asp
Facteur de risque : Moyen";
