The IWbemEventProviderSecurity::AccessCheck method is used by WMI event providers to check access permissions. This check occurs when a consumer tries to subscribe to an event. By definition, the AccessCheck method is passed the security identifier (SID) of the user who is trying to create the event registration. The consumer is permitted to subscribe to the event only if the consumer has access permission for the event. If this permission does not exist, the subscription is prevented. With Windows XP, when a permanent WMI event consumer is registered by a member of the local administrators group, the event provider's AccessCheck method is passed the local administrators group SID instead of the individual user's SID.
