- Boolean
Valeur Boolean qui spécifie si le serveur de publication est désinstallé du serveur de distribution sans vérifier que le serveur de publication a aussi désinstallé le serveur de distribution, si le serveur de publication se trouve sur un serveur séparé. Si la valeur est true, tous les objets de réplication associés au serveur de publication sont supprimés, même s'il n'est pas possible de joindre le serveur de publication sur un serveur distant. Si la valeur est false, la réplication vérifie d'abord que le serveur de publication distant a bien désinstallé le serveur de distribution.

Remarques
Lorsque force est défini sur true, vous devrez peut-être nettoyer toutes les métadonnées de publication restantes sur un serveur de publication distant.
Lorsque le serveur de publication se trouve sur le même serveur que le serveur de distribution, la réplication vérifie qu’il ne reste aucun objet de publication ou de distribution sur le serveur local.
La Remove méthode ne peut être appelée que par un membre du sysadmin rôle serveur fixe sur le serveur de distribution.
Appeler Remove équivaut à exécuter sp_dropdistpublisher sur le serveur de distribution.
