On continue dans la s\u00e9rie des articles Windows sur mon blog o\u00f9 autrefois, je parlais de Linux \ud83d\ude42
\nBon, tr\u00e8ve de plaisanterie, j’ai voulu installer des imprimantes sur un alias de serveur, genre \\\\mon_serveur_d_impression, quelle que soit la machine utilis\u00e9e r\u00e9ellement, disons \\\\vraisrv1.
\nL’objectif est de rendre transparente la conf sur les postes, si on d\u00e9cide de bouger les imprimantes ; et \u00e9viter de se payer une grosse reconfig de tous les PC…<\/p>\n

Je vous d\u00e9cris la manip en tenant compte du bug Microsoft qui va avec<\/strong> (ou de la feature de s\u00e9curit\u00e9, appelez \u00e7a comme vous voulez).
\nLe bug est le suivant : impossible d’acc\u00e9der \u00e0 un partage (fichier ou imprimante) en utilisant un alias (CNAME) d’une machine sur Windows serveur (au moins 2000 et 2003).<\/p>\n

Voici comment faire.<\/p>\n

Sur votre DNS, cr\u00e9ez le CNAME qui pointe de mon_serveur_d_impression et rechargez-le.
\nTestez, \u00e7a ne marche pas : net view vraisrv1<\/code> affiche les partages et net view mon_serveur_d_impression<\/code> n’affiche rien et crie au scandale avec un message compl\u00e8tement inappropri\u00e9 :<\/p>\n

C:\\>net view mon_serveur_d_impression\r\nL'erreur syst\u00e8me 52 s'est produite.\r\n\r\nVous n'\u00e9tiez pas connect\u00e9 car il y avait un nom en double sur le r\u00e9seau. Allez dans Syst\u00e8me dans le Panneau de configuration et modifiez le nom de l'ordinateur et essayez \u00e0 nouveau.\r\n<\/pre>\n
Appliquez donc la correction d\u00e9crite ici : http:\/\/support.microsoft.com\/?kbid=281308<\/a>, \u00e0 savoir, ajoutez une clef \u00ab\u00a0DisableStrictNameChecking\u00a0\u00bb \u00e0 valeur 1 dans la base de registre, \u00e0 l’emplacement \u00ab\u00a0HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\LanmanServer\\Parameters\u00a0\u00bb. A faire sur le serveur \u00ab\u00a0vraisrv1\u00a0\u00bb, celui pour lequel on veut cr\u00e9er un alias.
\nRed\u00e9marrez le service \u00ab\u00a0Serveur\u00a0\u00bb (correspondant \u00e0 LanmanServer) – \u00e7a, c’est pas dit dans la doc Microsoft – ou, plus simplement red\u00e9marrez le serveur. Car le service \u00ab\u00a0Serveur\u00a0\u00bb est central et il y a pas mal de d\u00e9pendances.<\/p>\n
Ensuite, le net view mon_serveur_d_impression<\/code> fonctionnera, ou, plus simplement, le \u00ab\u00a0D\u00e9marrer -> Ex\u00e9cuter -> \\\\mon_serveur_d_impression\u00a0\u00bb<\/p>\n
Avec un nom comme \u00ab\u00a0DisableStrictNameChecking\u00a0\u00bb, on pourrait presque croire que c’est un param\u00e8tre de s\u00e9curit\u00e9…. ils sont forts au marketting Windows. Je vois d’ici le transparent Powerpoint lors d’une grand-messe : \u00ab\u00a0nous avons permis un param\u00e8tre laxiste pour permettre de ne plus contr\u00f4ler le nom r\u00e9el du serveur\u00a0\u00bb. Traduction : \u00ab\u00a0on a corrig\u00e9 un bug bien moisi qu’on trouv\u00e9 des admins sachant g\u00e9rer un DNS et ayant compris \u00e0 quoi \u00e7a sert\u00a0\u00bb.<\/p>\n","protected":false},"excerpt":{"rendered":"
