  • Hi Ratman,

    From the Wikipedia entry for Security Identfier at http://en.wikipedia.org/wiki/Windows_SID :

    "In the context of the Microsoft Windows NT line of operating systems, a Security Identifier (commonly abbreviated SID) is a unique name (an alphanumeric character string) which is assigned by a Windows Domain controller during the log on process that is used to identify an object, such as a user or a group of users in a network of NT/2000 systems. SIDs are not portable.

    Windows grants or denies access and privileges to resources based on access control lists (ACLs), which use SIDs to uniquely identify users and their group memberships. When a user logs into a computer, an access token is generated that contains user and group SIDs and user privilege level. When a user requests access to a resource, the access token is checked by the ACL to permit or deny particular action on a particular object.

    SIDs are useful for troubleshooting issues with security audits, Windows server and domain migrations"

    No, the KeyUpdateTool.exe does not make any secuity changes to the system, and such, will not change the SID.
