    I clicked on administrator on the desktop and went into properties on the
    Startmenu shortcut. I clicked on the Security Tab and noted that the "Group
    or user names" list contains an "Account Unknown(S-1-5-21-lots of digits)"
    and the litlle 'head' icon has a red-circled 'x' attached to it. What is
    this? I assume it's some kind of problem. Anybody know?

    I clicked on administrator on the desktop and went into properties on the
    The S-1-5-21-... is known as a "security identifier" or SID. Internally all
    accounts are represented by a unique identifier. The names you put on the
    account is just a mapping ot one of those identifiers. You can change the
    name but the identifier stays the same.

    Most likely what you are seeing is a remnant from an account you have
    deleted that was granted access to the object you are looking at. When the
    account is deleted the system does not go through and remove all access
    control list entry the account was granted. When you go look at the access
    control list you will see the old entry, but the system can no longer resolve
    the SID to an account name, because the account no longer exists. Therefore,
    it shows you the SID instead.

    It is also possible that you run into this on a domain-joined computer when
    it is away from the domain. A domain account has been granted access to the
    object, but if the system is unable to resolve the SID listed in the access
    control list to the account name when you are looking at it it shows the SID.
    This could happen because the computer is unable to contact a domain
    controller.

    I wish you guys would all use Windows Mail for your newsgroup postings and
    include the original message in your replies. That way, someone willing to
    help, like me, would know what is going on when just downloading new
    messages.
